Description

The present invention relates to a vehicle door seal structure.

2. Description of the Related Art In a vehicle door in which a window glass opens and closes a window opening surrounded by a door sash (window frame), an elastic body is provided along the door sash to contact the peripheral edge of the window glass. The elastic body is made of a water-impermeable material such as rubber. The elastic body waterproofs the periphery of the window glass and suppresses vibrations of the window glass to stabilize it. As this type of elastic body, a glass run having a U-shaped cross-section surrounding three surfaces of the windshield, ie, the vehicle outer side, the vehicle inner side, and the peripheral edge, is widely used. In addition, along with the diversification of door structures, an elastic body having a form different from that of the existing glass run has been proposed.

For example, in Patent Document 1, in a side door of a vehicle in which an exterior panel of a door sash and a window glass are in a substantially flush relationship, an outer weatherstrip, which is an elastic body between the edges of the window glass and the exterior panel, is disclosed. is described.

JP 2017-88039 A

Since the outer weatherstripping of Patent Document 1 contacts the peripheral surface of the window glass, it is difficult to ensure a high level of sealing performance. For example, when viewed in a cross section perpendicular to the longitudinal direction of the door sash, the area where the outer weatherstrip and the window glass face each other is limited to the thickness of the window glass at most. Therefore, if there is variation in the position of the windshield and the outer weatherstrip in the vehicle interior and exterior direction, the outer weatherstrip may not be able to properly contact the peripheral surface of the windshield, resulting in a loss of sealing performance. .

Further, in Patent Document 1, an inner weatherstrip is provided that abuts against the surface of the window glass that faces the vehicle interior. However, the inner weatherstripping is in contact with the windshield at a position away from the periphery of the windshield and is constructed as a separate member from the outer weatherstripping. Therefore, a separate structure for sealing between the inner weatherstripping and the outer weatherstripping is required, which complicates the structure and requires time and effort for precision control in order to obtain a high degree of sealing performance.

It has an internal space of the structure.

The vehicle-exterior wall 33c is located on the vehicle-exterior side, and is aligned with the vehicle-exterior surface W1 of the window glass W and the vehicle-exterior surface 32a of the garnish 32 in the inner and outer peripheral directions. The inner peripheral side wall 33d extends from the inner peripheral side end of the vehicle outer side wall 33c to the lip portion 33b, and is positioned to face the edge surface W3 of the window glass W in the inner and outer peripheral directions. The outer peripheral side wall 33e and the outer peripheral protruding wall 33f form an L shape along the inner peripheral edge 32c of the garnish 32, the outer peripheral side wall 33e facing the inner peripheral side 32e, and the outer peripheral protruding wall 33f facing the end face 32g.

The vehicle inner side wall 33 g abuts on the outer peripheral extending portion 30 g of the inner sash 30 . The position of the elastic cover 33 (especially the hollow portion 33a) in the vehicle interior and exterior direction is determined by the contact of the vehicle interior side wall 33g with the outer peripheral extension portion 30g. At the door corner portion 10d where the connecting member 35 is provided, the inner side wall 33g also abuts on the bent portion 35h of the connecting member 35 (see FIGS. 16 to 18).

The inner peripheral side base wall 33h is formed at the corner between the inner peripheral side end of the vehicle inner side wall 33g and the lip portion 33b, and contacts the positioning portion 31c1 of the guide rail 31. As shown in FIG. The outer peripheral side base wall 33i connects the outer peripheral side end portions of the outer peripheral protruding wall 33f and the vehicle inner side wall 33g, and extends toward the outer peripheral side as it progresses from the vehicle inner side (vehicle inner side wall 33g) to the vehicle outer side (outer peripheral protruding wall 33f). It has a protruding slanted shape. With the inner peripheral side base wall 33h in contact with the positioning portion 31c1, the outer peripheral side base wall 33i is separated from the stepped portion 30c. The shape and size of the hollow portion 33a in the initial state are set so that a triangular space is formed between them (see FIG. 10). That is, the position of the elastic cover 33 in the inner and outer peripheral directions is determined by the contact of the inner peripheral side base wall 33h with the positioning portion 31c1.

In the hollow portion 33a, the inner side wall 33g and the inner base wall 33h are thicker, and the outer side wall 33c, the inner side wall 33d, the outer side wall 33e, and the outer protruding wall 33f are thinner. In other words, the hollow portion 33a has a large thickness and excellent stability at the portion held (positioned) in contact with the inner sash 30 and the guide rail 31 in the holding recess U1, and the window glass W and the garnish are provided. The portion sandwiched by 32 has a small thickness and is easily elastically deformed.

The lip portion 33b of the elastic cover 33 extends toward the inner peripheral side from between the inner peripheral side wall 33d of the hollow portion 33a and the inner peripheral side base wall 33h. A predetermined range of the base end side of the lip portion 33b connected to the hollow portion 33a is inserted into the gap U2 between the window glass W and the cover wall 31e, and the tip portion of the lip portion 33b extends inward from the gap U2. Protruding.

As shown in FIG. 10, the lip portion 33b in the initial state (free state) has a plane shape in which an interior side surface 33j facing the cover wall 31e is in a planar shape along the cover wall 31e. The side surface 33k has an uneven shape. More specifically, the base end portion of the vehicle outer side surface 33k near the hollow portion 33a (inner peripheral side wall 33d) is recessed toward the vehicle interior, and the inner peripheral side of the recessed portion is convex toward the vehicle exterior. . The thickness of the convex portion of the lip portion 33b in the vehicle interior and exterior direction is greater than the width of the gap U2.

A portion of the lip portion 33b protruding from the gap U2 toward the inner peripheral side is elastically deformable. The protruding portion of the lip portion 33b has a curved shape so as to protrude toward the vehicle interior as it progresses toward the inner peripheral side, and the tip of the lip portion 33b is positioned near the tip of the holding wall 31g of the guide rail 31. is doing.

As shown in FIG. 10, in the initial state (free state), the elastic cover 33 has a portion of the inner peripheral side wall 33d (a region near the lip portion 33b) of the hollow portion 33a and an outer side surface 33k of the lip portion 33b. The convex portion is in a relationship of overlapping with the window glass W. As shown in FIG. A portion of the outer peripheral side wall 33 e (region near the vehicle outer side wall 33 c ) of the hollow portion 33 a overlaps the garnish 32 . The overlapping portions of the elastic cover 33 are pressed by the window glass W and the garnish 32 and elastically deformed to assume the shape of the holding state shown in FIG.

In the holding state of FIG. 11, the inner peripheral side wall 33d of the hollow portion 33a of the elastic cover 33 is pressed from the window glass W while forming a shape along the edge surface W3. The pressing force from the window glass W acts toward the outer peripheral side so as to press the hollow portion 33a against the garnish 32, and the outer peripheral side wall 33e increases the degree of close contact with the inner peripheral side surface 32e of the garnish 32. Further, the garnish 32 also applies a pressing force toward the inner peripheral direction to the hollow portion 33a, and the inner peripheral side wall 33d is brought into close contact with the edge surface W3 of the window glass W. As shown in FIG. Therefore, the hollow portion 33a of the elastic cover 33 is elastically deformed in the inner and outer peripheral directions and adheres to both the window glass W and the garnish 32, thereby closing the gap between the window glass W and the garnish 32 in a watertight manner. The outer wall 33c of the hollow portion 33a is substantially flush with the outer surface W1 of the window glass W and the outer surface 32a of the garnish 32. As shown in FIG.

When the inner peripheral side wall 33d of the hollow portion 33a is pressed against the edge surface W3 of the window glass W due to the inclined shape in the initial state (see FIG. 10), the inner peripheral side wall 33d exerts a pressing force toward the vehicle interior in addition to the outer periphery. also receive That is, the hollow portion 33a is pressed by the component force from the window glass W toward the outer periphery and the component force toward the vehicle interior. As a result, the inner side wall 33g is pressed against the outer peripheral extension portion 30g. Due to this pressing, a force acts to spread the vehicle inner side wall 33g in the inner and outer peripheral directions. Since the inner peripheral side base wall 33h has a shape that abuts on the positioning portion 32c1 in the initial state (FIG. 10), the inner peripheral side base wall 33h maintains close contact with the positioning portion 32c1 to extend the hollow portion 33a in the inner and outer peripheral directions. position. On the other hand, there is sufficient space between the outer peripheral side base wall 33i and the stepped portion 30c in the initial state (FIG. 10), and the hollow portion 33a reduces the space between the stepped portion 30c and the outer peripheral side base wall 33i. Meanwhile, the portion from the outer peripheral side base wall 33i to the outer peripheral protruding wall 33f is pressed against the vehicle exterior extension portion 30h.

In the holding state of the elastic cover 33 shown in FIG. 11, the convex portion of the vehicle exterior side surface 33k of the lip portion 33b is further pressed by the vehicle interior side surface W2 of the window glass W, and the lip portion 33b is compressed and deformed in the vehicle interior and exterior direction to form a gap. The inside of U2 is sealed watertight. In addition to sealing by the hollow portion 33a on the edge surface W3 of the window glass W, by sealing by the lip portion 33b on the vehicle interior side surface W2 of the window glass W, the watertightness between the window glass W and the vertical pillar sash 12 is improved. Further improve.

In particular, in the door 10 of this embodiment, the components of the window regulator 40 are incorporated in the vertical pillar sash 12 as will be described later. Therefore, it is highly effective to seal the gap between the window glass W and the vertical column sash 12 with the elastic cover 33 in a highly watertight state.

In the elastic cover 33, the portion held by the holding recess U1 and sandwiched between the window glass W and the garnish 32 is made into the hollow portion 33a. It is a seal member with excellent stability in cross-sectional structure. As a result, the hollow portion 33a of the elastic cover 33 and its peripheral members (the inner sash 30, the guide rail 31, the garnish 32, etc.) is absorbed by the variation in accuracy of parts and assembly, and the hollow portion 33a is securely attached to the window glass with an appropriate contact pressure. W can be brought into close contact with each portion of the vertical column sash 12 (the stepped portion 30c, the positioning portion 31c1, and the inner peripheral edge portion 32c of the garnish 32) to obtain high watertight performance.

Further, even if the gap between the window glass W and the garnish 32 varies in the inner and outer peripheral directions, the hollow portion 33a can maintain a stable width in appearance in the inner and outer peripheral directions.

Further, in the hollow portion 33a in the initial state (FIG. 10), the outer peripheral side base wall 33i has a predetermined space between it and the stepped portion 30c, and the space is made smaller when the held state (FIG. 11) is set. By adopting a configuration in which the elastic cover 33 is elastically deformed, the accuracy variation absorbing performance is improved.

The hollow portion 33a in the held state of FIG. 11 has a substantially L-shaped outer peripheral side wall 33e and an outer peripheral protruding wall 33f fitted to the inner peripheral edge portion 32c of the garnish 32, so that higher stability can be obtained. As described above, due to the inclined shape of the inner peripheral side wall 33d in the initial state (FIG. 10), the hollow portion 33a receives a pressing force from the window glass W toward the outer peripheral side and the vehicle inner side, and the vehicle inner side wall 33g is pushed toward the inner sash 30. , and is restricted from moving toward the inside of the vehicle. Further, the outer peripheral protruding wall 33f faces the end surface 32g of the inner peripheral edge portion 32c of the garnish 32, thereby restricting movement (dropping) of the hollow portion 33a to the outside of the vehicle. Therefore, the hollow portion 33a is stably held in the vehicle interior and exterior directions.

Although the details will be described later, the first section S1 of the guide rail 31 is a portion that slidably supports the shoes 43 and 44 of the sliders 45 and 46 that support the window glass W. As shown in FIG. That is, the inner peripheral side wall 31b and the partition wall 31f forming the first section S1 of the guide rail 31 determine the position of the window glass W in the inner and outer peripheral directions, and the vehicle inner side wall 31a and the holding wall 31g determine the position of the window in the vehicle inner and outer directions. The position of the glass W is determined. A positioning portion 31 c 1 that positions the elastic cover 33 in the inner and outer peripheral directions is a part of the guide rail 31 . That is, both the window glass W and the elastic cover 33 are positioned using the guide rail 31 as a reference. As a result, the positional relationship between the window glass W and the elastic cover 33 is stabilized (difficult to vary). Since the elastic cover 33 functions as a sealing member by being pressed by the window glass W in the held state (FIG. 11), if the positional relationship between the window glass W and the elastic cover 33 is stable, the window glass W and the pillar sash 12 The degree of close contact of the elastic cover 33 to each part of is stabilized, and a high degree of watertightness by the elastic cover 33 can be ensured. As will be described later, since the elastic cover 33 causes the lip portion 33b to abut against the sliders 45 and 46, if the positional relationship between the window glass W and the elastic cover 33 is stable, the load applied to the sliders 45 and 46 will not change. Also, the sliding performance of the sliders 45 and 46 with respect to the guide rail 31 is improved.

The garnish 32 and the elastic cover 33 are parts that form the appearance of the pillar sash 12 when the door 10 is viewed from the outside of the vehicle. The vertical pillar sash 12 has a so-called flush surface structure in which the garnish 32 is aligned with the vehicle outer side surface W1 of the window glass W in a substantially flush positional relationship. As described above, the elastic cover 33 is held in a highly accurate and stable state in which the hollow portion 33a is not likely to bulge out toward the outside of the vehicle. An aesthetic flush surface structure appearance can be configured.

In the garnish 32, the position of the parting line L1 generated by molding is set inside the vehicle from the intersection point K1 on the inner peripheral side surface 32e of the inner peripheral edge portion 32c (the position where the vehicle inner side surface 32b is extended) ( See Figure 13). As a result, the parting line L1 can be reliably covered with the elastic cover 33 even if there is some variation in accuracy. Since the parting line L1 does not appear in the appearance, the appearance of the garnish 32 is good, which contributes to improving the appearance of the pillar sash 12. - 特許庁

Further, the elastic cover 33 is located on the inside of the window glass W and covers most of the guide rail 31, in addition to the hollow portion 33a that appears directly in the external appearance of the pillar sash 12 between the window glass W and the garnish 32. A lip portion 33b covering from the outside of the vehicle is provided. As a result, the internal structure of the vertical column sash 12 is covered on the inner peripheral side of the garnish 32 so as not to appear in the external appearance, and an excellent appearance is obtained even in the region where the window glass W and the vertical column sash 12 overlap in the vehicle interior and exterior directions.

When attaching the elastic cover 33 to the upright pillar sash 12, as shown in FIG. 12, the window glass W is not present at the cross-sectional position of the upright pillar sash 12 to be attached. Specifically, the window glass W is lowered to the fully open position (see FIG. 20). In this state, the elastic cover 33 is tilted as shown in FIG. 12, and the hollow portion 33a is inserted in the direction of the arrow IN. The hollow portion 33a passes between the positioning portion 31c1 of the guide rail 31 and the inner peripheral edge portion 32c of the garnish 32 and enters the holding recess portion U1. At this time, the outer peripheral base wall 33i of the elastic cover 33 and the inner peripheral side surface 32e of the garnish 32 come into contact with each other. The outer peripheral side base wall 33i and the inner peripheral side surface 32e have an inclined shape that pushes the hollow portion 33a inward as it proceeds in the insertion direction (arrow IN). Therefore, the hollow portion 33a is inserted into the holding recess U1 through the positioning portion 31c1 while being compressed in the inner and outer peripheral directions. Since the outer peripheral side base wall 33i and the inner peripheral side surface 32e are smoothly inclined to each other, the hollow portion 33a can be smoothly inserted into the holding recess U1.

After the hollow portion 33a is inserted into the holding recess U1 along the arrow IN in FIG. 12, the elastic cover 33 is rotated clockwise in FIG. Then, the outer peripheral side wall 33e and the outer peripheral protruding wall 33f of the elastic cover 33 are fitted to the inner peripheral edge portion 32c of the garnish 32, and the elastic cover 33 is stably held as shown in FIG. At this time, the positioning portion 31c1 and the inner peripheral edge portion 32c prevent the hollow portion 33a of the elastic cover 33 from falling off from the holding recess portion U1 to the inner peripheral side and the vehicle outer side. That is, the hollow portion 33a of the elastic cover 33 is positioned in both the vehicle interior and exterior directions and the vehicle interior and exterior perimeter directions with respect to the holding recess U1. Therefore, the attached elastic cover 33 is stably held by the upright sash 12 even when the window glass W is opened (the window glass W is omitted from FIG. 10).

As described above, the cross-sectional structures of the upper sash 11 and the vertical column sash 12 are partially different. The upper sash 11 and the vertical pillar sash 12 having different cross-sectional structures are connected via the connecting member 35 at the door corner portion 10d. The connection member 35 is manufactured by die-casting a metal such as aluminum. The connection member 35 has a first frame portion 35 a positioned on an extension of the upper sash 11 and a second frame portion 35 b positioned on an extension of the pillar sash 12 .

The front end of the first frame portion 35 a of the connecting member 35 forms a contact end surface 35 c that faces the rear end of the sash body 20 of the upper sash 11 . The contact end surface 35c has a shape including the frame portion 20a and the plate-like portion 20b of the sash body 20, and the area corresponding to the hollow portion of the frame portion 20a is closed by the contact end surface 35c. As a result, the rear end face of the sash body 20 can be reliably brought into contact with the contact end face 35c.

35 d of insertion protrusions which protrude toward the front from the contact end surface 35c are provided (refer FIG. 6, FIG. 7). The insertion projection 35d has a shape that follows the inner surface of the hollow frame portion 20a. inserted within. In this state, the connection member 35 and the sash body 20 are joined together by means of welding or the like.

The upper end of the connecting member 35 has a plate-like portion 35i that is continuous with the plate-like portion 20b of the upper sash 11 in a state where the upper sash 11 and the first frame portion 35a are joined. A weatherstrip (not shown) held by the weatherstrip holding portion 24 of the upper sash 11 extends onto the connecting member 35 and is continuously held by the plate-like portion 35i.

The lower end of the second frame portion 35b of the connecting member 35 has a shape corresponding to the portion of the inner sash 30 of the standing pillar sash 12 excluding the design portion 30b. More specifically, the connection member 35 has a vehicle interior side wall 35e that continues to the vehicle interior side wall 30d, an inner peripheral side wall 35f that continues to the inner peripheral side wall 30e, and an outer peripheral side wall 35g that continues to the outer peripheral side wall 30f. In addition, a bent portion 35h that is continuous with a portion of the inner peripheral side of the outer peripheral extension portion 30g is provided at the end portion of the outer peripheral side wall 35g on the vehicle outer side.

The inner peripheral side wall 35f of the second frame portion 35b partially differs in thickness in the inner and outer peripheral directions. The thickness of the inner peripheral side wall 35f is large near the lower end of the second frame portion 35b, and an insertion protrusion 35j that protrudes downward from the lower end surface of the inner peripheral side wall 35f is provided (see FIGS. 6 and 7). . The insertion projection 35j has a shape along the inner surface of the frame portion 30a of the inner sash 30, and when the upper end surface of the inner sash 30 is in contact with the lower end surface of the second frame portion 35b, the insertion projection 35j is inserted. is inserted into the frame portion 30a. In this state, the connection member 35 and the inner sash 30 are joined by means such as welding.

The design portion 30 b and the stepped portion 30 c of the inner sash 30 (the entire exterior extension portion 30 h and a portion of the outer periphery extension portion 30 g on the outer peripheral side) extend to the upper end of the pillar sash 12 . Above the joining point between the lower end surface of the second frame portion 35b and the upper end surface of the inner sash 30, the connecting member 35 is in contact with the vertically extending side contact surface 30i formed on the stepped portion 30c. The edge of the bent portion 35h abuts (see FIGS. 16 to 18).

As shown in FIGS. 16 and 17, the vehicle-exterior end of the inner peripheral side wall 35f abuts on the bent portion 31d of the guide rail 31, and the position of the connecting member 35 relative to the inner sash 30 in the vehicle interior-exterior direction is determined. Inside the second frame portion 35b joined to the upright pillar sash 12, similarly to the general cross-sectional portion of the upright pillar sash 12 (FIG. 9), there are a vehicle interior side wall 35e, an inner peripheral side wall 35f, an outer peripheral side wall 35g, and a guide rail 31. A third section S3 is formed surrounded by the vehicle interior side wall 31a.

By joining the first frame portion 35a and the second frame portion 35b to the sash main body 20 and the inner sash 30, respectively, as described above, the upper sash 11 and the standing pillar sash 12 are connected via the connection member 35 to form a door corner portion. 10d is formed.

A vehicle interior side wall 35e of the connection member 35 has an L-shaped shape extending forward and downward from the vicinity of the upper end of the vertical column sash 12 when viewed from the vehicle interior side as shown in FIG. and the vehicle interior side wall 30d of the vertical column sash 12 are substantially flush with each other. An inner peripheral side wall 35f of the connecting member 35 extends forward and downward while curving, and is substantially flush with the inner peripheral side wall 20d of the upper sash 11 and the inner peripheral side wall 30e of the vertical column sash 12, respectively. Become. Similarly, the outer peripheral side wall 35g of the connecting member 35 extends forward and downward while being curved, and is substantially flush with the outer peripheral side wall 20e of the upper sash 11 and the outer peripheral side wall 30f of the vertical column sash 12, respectively. Become. That is, the frame portion 20a of the upper sash 11 (excluding the vehicle outer wall 20f) and the frame portion 30a of the vertical column sash 12 are smoothly connected by the first frame portion 35a and the second frame portion 35b of the connection member 35. .

The connection member 35 changes the internal shape of the second frame portion 35b according to the difference in vertical position. As shown in FIGS. 16 and 17, unlike the inner peripheral side wall 30e (see FIG. 9) of the inner sash 30 in the general cross section, the inner peripheral side wall 35f of the second frame portion 35b is connected to the vehicle inner side wall 35e. The thickness gradually increases as it progresses from the center to the outside of the vehicle. The inner peripheral side wall 35f overlaps a part of the guide rail 31 in the inner and outer peripheral directions, and the inner peripheral side wall 35f is provided with a stepped portion 35k having a shape that fits in the corner of the boundary between the vehicle inner side wall 31a and the inner peripheral side wall 31b. are formed (see FIGS. 16 and 17). Further above the second frame portion 35b, as shown in FIG. 18, an inner peripheral side wall 35f extends forward and continues to the first frame portion 35a.

The second frame portion 35b also partially differs in thickness in the vehicle interior and exterior direction with respect to the vehicle interior side wall 35e. In the vicinity of the lower end of the second frame portion 35b, the thickness of the inner side wall 35e is substantially the same as the thickness of the inner side wall 30d of the inner sash 30. As shown in FIG. As shown in FIGS. 6, 16, and 17, the vehicle interior side wall 35e extends upward while generally maintaining this thickness, and the third section S3 extends to a position near the upper end of the vertical column sash 12 in the vehicle interior and exterior directions. Wide width is guaranteed.

As shown in FIGS. 6 and 18, further above the second frame portion 35b (position on the rearward extension of the first frame portion 35a), a region continuing upward from the vehicle interior side wall 35e is partially guided. A thick portion 35m is formed by increasing the thickness of the rail 31 to a position close to the vehicle inner side wall 31a. The thick portion 35m forms a seat surface facing the outside of the vehicle, and communicates with the escape recess 35n, which is a part of the third section S3, and the escape recess 35n by recessing the seat surface toward the inside of the vehicle. A screw hole 35p is formed. The escape recess 35n has a first region located on the vehicle inner side of the first section S1 and the second section S2 along the vehicle interior side wall 31a, and a portion of the first region corresponding to the first section S1 on the vehicle inner side. It is a space having an L-shaped cross-sectional shape with an extended second region. The screw hole 35p is a cylindrical hole formed by extending a portion corresponding to the second section S2 of the first region of the escape recess 35n toward the vehicle interior, and has a female screw formed on the inner peripheral surface. Both the relief recess 35n and the screw hole 35p are bottomed recesses or holes recessed from the vehicle outer side toward the vehicle inner side, and penetrate (open) the vehicle inner side surface of the second frame portion 35b. not

As described above, the connection member 35 having a complicated structure in which the cross-sectional shape and thickness are different depending on the longitudinal position of the door sash 10b can be manufactured with high precision by die casting. In addition, since the die-cast connection member 35 can be formed with a bottomed screw hole 35p, a thick portion 35m, etc., inside with high accuracy without forming a die-cutting hole for molding on the outer surface. , it is possible to achieve both high internal functionality and excellent appearance.

As shown in FIG. 4, the pillar sash 12 further has an inner cover 36 that covers the inner sash 30 and the connection member 35 from the inside of the vehicle. Note that the inner cover 36 is omitted from the cross-sectional views of the pillar sash 12 (FIGS. 9 to 11 and FIGS. 14 to 18). The inner cover 36 includes a frame portion 36a having a cross-sectional shape substantially corresponding to the cross-sectional shape of the frame portion 30a of the inner sash 30 and the second frame portion 35b of the connecting member 35, and a plate-shaped portion projecting outward from the frame portion 36a. and a portion 36b.

The plate-like portion 36 b of the inner cover 36 has a shape that is continuous with the plate-like portion 35 i of the connecting member 35 . A weatherstrip holder (not shown), which is a separate component, is attached from the plate-like portion 35i to the plate-like portion 36b. The weatherstrip is held continuously from the weatherstrip holding portion 24 (see FIG. 2) of the upper sash 11 to the weatherstrip holding portions on the plate-like portion 35i and the plate-like portion 36b, and the door sash 10b including the door corner portion 10d. is arranged over the entire outer peripheral portion of the

The door 10 includes a window regulator 40 (see FIGS. 8 and 22 to 24) that drives the window glass W to move up and down. A window regulator 40 is incorporated in the upright sash 12 .

The window regulator 40 has two upper and lower shoe bases 41 and 42 fixed to the window glass W, and is attached to each of the shoe bases 41 and 42 so as to be vertically slidable on the guide rail 31. It has two upper and lower shoes 43 and 44 . As shown in FIGS. 8 and 21, a shoe 43 is attached to a shoe base 41 to form an upper slider 45, and a shoe 44 is attached to a shoe base 42 to form a lower slider 46. As shown in FIGS. The guide rails 31 forming the columnar sash 12 together with the inner sash 30 also function as guide portions for guiding the sliders 45 and 46 in the window regulator 40 to move up and down.

The guide rail 31 extends downward longer than the inner sash 30 and the inner cover 36 (see FIGS. 3 and 4), so that the guide rail 31 is not surrounded by the inner sash 30 and the inner cover 36 in the interior space of the door panel 10a. exposed to. A motor unit 50 having a motor M as a drive source for the window regulator 40 is attached to the exposed portion of the guide rail 31 in the interior space of the door panel 10a (see FIGS. 1, 8 and 19).

One end of each of the first wire 52 and the second wire 53 is connected to the winding drum 51 (see FIGS. 8 and 22 to 24) built in the motor unit 50 . The first wire 52 extends upward from the winding drum 51, is wound around a guide pulley 54 rotatably supported near the upper end of the guide rail 31 (door corner portion 10d), and turns downward. , and the other end is connected to the shoe base 41 of the slider 45 from above. The second wire 53 extends upward from the winding drum 51 and has the other end connected to the shoe base 41 of the slider 45 from below.

When the motor M of the motor unit 50 is driven to rotate the winding drum 51, the winding amounts of the first wire 52 and the second wire 53 relative to the spiral groove formed on the peripheral surface of the winding drum 51 change relatively. do. When the winding drum 51 is rotated in the first direction to increase the winding amount of the first wire 52 , the slider 45 (shoe base 41 ) is pulled upward by the first wire 52 to move the shoe 43 to the guide rail 31 . The slider 45 moves upward while being slid. When the winding drum 51 is rotated in the second direction to increase the amount of winding of the second wire 53 , the slider 45 (shoe base 41 ) is pulled downward by the second wire 53 to move the shoe 43 to the guide rail 31 . The slider 45 moves downward while being slid. The wires 52 and 53 opposite to the side where the amount of winding increases are let out (relaxed) from the winding drum 51 and follow the movement of the slider 45 . When the slider 45 moves up and down, the window glass W fixed to the shoe base 41 moves up and down. A slider 46 fixed to the window glass W via the shoe base 42 moves together with the window glass W while sliding the shoe 44 on the guide rail 31, thereby stabilizing the attitude of the window glass W. A detailed structure of the window regulator 40 that operates as described above will be described.

Of the elements constituting the sliders 45 and 46, the shoe bases 41 and 42 fixed to the window glass W are rigid bodies made of metal or the like. Each of the shoes 43 and 44 slidingly moved with respect to the guide rail 31 has a hardness higher than that of the metal or the like that constitutes the guide rail 31 in order to achieve smooth movement while preventing noise and vibration. It is made of low synthetic resin or the like.

As shown in FIGS. 8 and 21, the shoe base 41 is elongated in the vertical direction, and includes a glass support portion 41a positioned on the outside of the vehicle, a connection portion 41b projecting from the glass support portion 41a toward the vehicle interior, and a connection portion 41a. and a shoe support portion 41c provided at the vehicle-inside end of 41b. As shown in FIGS. 15 and 16, the glass support portion 41a is a plate-shaped portion whose front and back surfaces (side surfaces) face toward the interior and exterior of the vehicle. Oppose. The connecting portion 41b is a plate-like portion that protrudes from the inner side surface of the glass supporting portion 41a and has both side surfaces facing in the inner and outer peripheral directions. That is, the glass supporting portion 41a and the connecting portion 41b of the shoe base 41 have a substantially T-shaped cross section perpendicular to the longitudinal direction (see FIG. 25A).

The glass supporting portion 41a and the connecting portion 41b each have a load reducing portion 41d and a load reducing portion 41e at both ends in the longitudinal direction. The surface of the glass support portion 41a facing the inside of the vehicle is a tapered surface that inclines toward the outside of the vehicle as it progresses toward the tip in the vicinity of the end in the longitudinal direction. ) is the load reduction section 41d. As shown in FIG. 25(B), in the vicinity of the ends in the longitudinal direction of the connecting portion 41b, the side surfaces facing the inner circumference and the side surfaces facing the outer circumference are tapered surfaces 41e1 that decrease the distance between them toward the tip. A portion tapered (a shape in which the cross-sectional area gradually decreases) due to these tapered surfaces 41e1 is the load reducing portion 41e.

The surface of the glass support portion 41a facing the vehicle exterior side is fixed to the vehicle interior side surface W2 of the window glass W by adhesion or the like. A portion of the upper end side of the connecting portion 41b protrudes toward the inside of the vehicle to a greater extent and passes between the inner peripheral side wall 31b of the guide rail 31 and the holding wall 31g and enters the first section S1 (FIG. 15). , see FIG. 16). A shoe support portion 41c is provided on a projecting portion of the connection portion 41b inserted into the first section S1. The shoe support portion 41c has an L-shaped cross-sectional shape formed by bending the end portion of the connection portion 41b toward the outer periphery, and the shoe 43 is attached to the shoe support portion 41c (see FIGS. 15 and 16). ).

As shown in FIGS. 8 and 21, the shoe 43 has a vertically elongated shape, and has a sliding base 43a positioned in the middle in the longitudinal direction and first elastic contact points protruding from the upper and lower ends of the sliding base 43a, respectively. It has a portion 43b and a second elastic contact portion 43c. The sliding base 43 a has a solid structure with a substantially rectangular cross-sectional shape perpendicular to the longitudinal direction of the shoe 43 . The shoe support portion 41c is inserted into the slide base portion 43a, and the slide base portion 43a is fixed to the shoe support portion 41c via a connection pin 47 (see FIG. 15).

The first elastic contact portion 43b is an elongated ring-shaped body projecting from the upper end surface of the sliding base portion 43a. A hollow portion between the curved portions penetrates in the inner and outer peripheral directions. Due to this shape, the first elastic contact portion 43b is easily elastically deformed in the vehicle interior and exterior directions.

The second elastic contact portion 43c is an elongated ring-shaped portion that protrudes from the lower end surface of the sliding base portion 43a. A hollow portion between the curved portions penetrates toward the inside and outside of the vehicle. Due to this shape, the second elastic contact portion 43c is easily elastically deformed in the inner and outer peripheral directions.

The shoe 43 is inserted into the first section S1 of the guide rail 31 (see FIGS. 15 and 16). A connection portion 41 b connecting the glass support portion 41 a and the shoe support portion 41 c in the shoe base 41 passes between the inner peripheral side wall 31 b and the holding wall 31 g and does not interfere with the guide rail 31 . Four outer surfaces of the sliding base portion 43a having a rectangular cross section are slidably opposed to the inner side wall 31a, the inner peripheral side wall 31b, the partition wall 31f, and the holding wall 31g of the guide rail 31 surrounding the first section S1. abut. As a result, the shoe 43 is supported so as to be vertically slidable in the first section S1 while its movement relative to the guide rail 31 in the vehicle interior and exterior directions and the vehicle interior and exterior perimeter directions is restricted.

The first elastic contact portion 43b of the shoe 43 faces the vehicle interior side wall 31a and the holding wall 31g facing in the vehicle interior and exterior directions in the first section S1 (see FIG. 18). The first elastic contact portion 43b is biased toward either the vehicle interior side or the vehicle interior side, and tries to maintain contact with either the holding wall 31g or the vehicle interior side wall 31a. This suppresses rattling of the shoe 43 in the vehicle interior and exterior directions. In this embodiment, the first elastic contact portion 43b is urged in a direction (vehicle outer side) in contact with the holding wall 31g (see FIG. 18).

The second elastic contact portion 43c of the shoe 43 faces the inner peripheral side wall 31b and the partition wall 31f facing each other in the inner and outer peripheral directions in the first section S1. The second elastic contact portion 43c is biased toward either the inner peripheral side or the outer peripheral side, and tries to maintain contact with either the inner peripheral side wall 31b or the partition wall 31f. This suppresses rattling of the shoe 43 in the inner and outer peripheral directions.

Compared to the first elastic contact portion 43b and the second elastic contact portion 43c, which are thin, hollow, and elastically deformable, the sliding base portion 43a has a solid structure with a large thickness and a high hardness. With respect to 31, it is possible to slide while determining the position with high accuracy both in the vehicle inner and outer directions and in the inner and outer peripheral directions.

The lip portion 33b of the elastic cover 33 is in a free state (as shown in FIG. 9, the state in which the base portion is only held between the inner side surface W2 of the window glass W and the cover wall 31e of the guide rail 31). is located on the locus of movement of the shoe base 41 . Therefore, when the slider 45 is moved up and down while being supported by the guide rail 31 via the shoe 43, the lip portion 33b abuts against the shoe base 41 and is elastically deformed under pressure.

More specifically, FIGS. 9-11 and 14-18 show the shape of the lip portion 33b in the free state. The shape of the lip portion 33b in contact with the shoe base 41 is shown in FIGS. 25(A) and 25(B). 25A shows a cross section perpendicular to the longitudinal direction of the shoe base 41, and FIG. 25B shows a cross section along the longitudinal direction of the shoe base 41. FIG. As shown in FIG. 25(A), the lip portion 33b has an intermediate portion passing through a position close to the corner portion on the outer peripheral side of the glass support portion 41a and the inner side of the vehicle, and a tip portion on the outer peripheral surface of the connecting portion 41b. abut. By pressing the tip portion from the shoe base 41, the lip portion 33b is elastically deformed toward the vehicle inner side and the outer peripheral side with the point sandwiched between the vehicle interior side surface W2 of the window glass W and the cover wall 31e as a fulcrum. The one-dot chain line in FIG. 25A shows the shape of the lip portion 33b before elastic deformation. Since the lip portion 33b originally has a curved shape that is easily elastically deformed in that direction, the shoe base 41 can be smoothly deformed without applying an excessive load.

Further, load reducing portions 41e are formed at both end portions of the connection portion 41b where the tip portion of the lip portion 33b is first pushed by the shoe base 41 moving up and down. As shown in FIG. 25(B), the load reducing portion 41e has tapered surfaces 41e1 provided on both sides in the inner and outer peripheral directions. It has a tapered shape that reduces the contact pressure on 33b. Therefore, the moving shoe base 41 always starts pressing the lip portion 33b smoothly with a small load by the load reducing portion 41e.

Similarly to the load reduction portions 41e of the connection portion 41b, the load reduction portions 41d provided at both ends of the glass support portion 41a have the effect of reducing the load when contacting the lip portion 33b. As indicated by the dashed line in FIG. 25A, the lip portion 33b is designed so as not to come into contact with the glass support portion 41a in a free state where it is not pressed by the connection portion 41b. there is Therefore, the load reducing portion 41d functions only when the lip portion 33b comes closer to the glass support portion 41a than the designed position due to variations in accuracy or the like, and plays an auxiliary role.

As a result of providing the load reducing portion 41e and the load reducing portion 41d on the shoe base 41 as described above, smooth elastic deformation of the lip portion 33b and smooth elastic deformation of the lip portion 33b can be achieved without causing catching or the like between the shoe base 41 and the lip portion 33b. Smooth movement of the shoe base 41 can be realized. In addition, an effect of suppressing abnormal noise (chattering noise of the lip portion 33b, etc.) generated between the shoe base 41 and the lip portion 33b can be obtained. The load reducing portion 41e and the load reducing portion 41d on the upper end side contribute to improving the smoothness of the operation when the shoe base 41 moves upward. contributes to smoother operation when moving downward.

The connecting portion 41b of the shoe base 41 is changed to have tapered surfaces 41e1 on both the inner and outer peripheral sides as in the load reducing portion 41e, and the tip of the lip portion 33b abuts on the outer peripheral side. It is also possible to employ an asymmetrical structure in which only the surface has the tapered surface 41e1.

Like the shoe base 41, the shoe base 42 has a vertically elongated shape, and includes a glass support portion 42a located on the outside of the vehicle, a connection portion 42b projecting from the glass support portion 42a toward the vehicle interior, and a connection portion 42b extending from the vehicle. and a shoe support portion 42c provided at the inner end (see FIGS. 8 and 21).

The shoe base 42 has substantially the same structure as the shoe base 41 described above (a structure in which the glass support portion 41a, the connection portion 41b, and the shoe support portion 41c are turned upside down). Since the arrangement and role of the shoe base 41 are the same as those of the shoe base 41, detailed description thereof will be omitted. The load reduction portions 41d and 42e (tapered surfaces 41e2) formed at the upper and lower ends of the glass support portion 42a also function in the same manner as the load reduction portions 41d and 41e of the shoe base 41. 25(A) and 25(B), the reference numerals of the parts of the shoe base 42 corresponding to those of the shoe base 41 are shown in parentheses.

The shoe 44 has a solid sliding base portion 44a, and a first elastic contact portion 44b and a second elastic contact portion 44c projecting from the lower end and the upper end of the sliding base portion 44a, respectively. The sliding base portion 44a, the first elastic contact portion 44b, and the second elastic contact portion 44c have substantially the same structure as the sliding base portion 43a, the first elastic contact portion 43b, and the second elastic contact portion 43c of the shoe 43 described above, respectively. (Structure in which the top and bottom of the first elastic contact portion 43b and the second elastic contact portion 43c are reversed). Description is omitted.

As described above, the lower slider 46 has the same basic structure as the upper slider 45 . FIG. 15 shows a cross-sectional position passing through the slider 45. In order to show that the slider 46 is also guided by the guide rail 31 in the same way, the reference numerals representing the constituent elements of the slider 46 are shown in parentheses. is doing.

As shown in FIG. 20, the shoe base 41 of the slider 45 and the shoe base 42 of the slider 46 each support the trailing edge side of the window glass W along the vertical column sash 12 . The glass support portion 41a of the upper shoe base 41 is fixed to the window glass W over a vertical range E1 (FIG. 20) extending downward from the vicinity of the upper end of the rear edge of the window glass W. . The lower glass support portion 42a of the shoe base 42 is fixed to the window glass W over a vertical range E2 (FIG. 20) extending upward from the vicinity of the lower end of the trailing edge of the window glass W. .

Since the sliders 45 and 46 that constitute the window regulator 40 support the window glass W at positions that are greatly separated from each other in the vertical direction, the positional accuracy and stability of the window glass W are extremely high along the pillar sash 12 . getting higher. In particular, as shown in FIG. 20 , the rear edge of the window glass W along the pillar sash 12 is vertically longer than the front edge along the front sash 13 . By arranging the sliders 45 and 46 apart from each other near the upper end and the lower end of the rear edge of the window glass W, the effective vertical support length for the window glass W becomes very large, and one side in the front-rear direction is extended. Sufficient stability and support strength can be obtained even with a structure in which the window glass W is supported only by the edge of the frame.

The upper slider 45 has a shoe 43 near the upper end of the shoe base 41, and the lower slider 46 has a shoe 44 near the lower end of the shoe base 42 (FIGS. 8 and 21). , FIGS. 23 and 24). As a result, the largest shoe pitch (the vertical distance between the two shoes 43 and 44) is obtained within the vertical range in which the shoe bases 41 and 42 are provided. The larger the shoe pitch, the easier it is to suppress the tilting of the window glass W with respect to the guide rail 31 (especially the tilting in the inner and outer peripheral directions), so that the window glass W can be supported with high precision and with high stability.

In the upright sash 12 that supports the window glass W with such excellent accuracy and stability, elastic members such as the glass run 23 of the upper sash 11 that sandwich and hold the window glass W in and out of the vehicle are provided. Not provided. The elastic cover 33 with which the rear edge of the window glass W abuts provides waterproofness between the window glass W and the vertical pillar sash 12 (garnish 32), and also functions as an external component of the vertical pillar sash 12. Compared to the run 23, it can be compact and simple in cross section.

As shown in FIGS. 8 and 21, the shoe base 41 that constitutes the upper slider 45 further has a portion that connects the first wire 52 and the second wire 53 . Below the shoe support portion 41c (see FIG. 8), a pair of upper and lower arms protruding laterally from the connection portion 41b are provided. be provided. The wire end support portions 41f and 41g are formed integrally with the body portion of the shoe base 41, respectively.

With the shoe 43 inserted into the first section S1 of the guide rail 31, the wire end support portions 41f and 41g enter the second section S2 (see FIG. 17). A wire insertion hole 41h and a wire insertion hole 41i penetrating vertically are formed in each of the wire end support portions 41f and 41g. Both of the wire insertion holes 41h and 41i are open only at both ends in the vertical direction, and are closed cross-sectional holes that do not have openings in the lateral direction (the inner and outer peripheral directions to the vehicle interior and exterior directions).

A first wire 52 is inserted into the wire insertion hole 41h of the wire end support portion 41f, and a wire end 55 to which the end portion of the first wire 52 is connected is positioned below the wire end support portion 41f. The first wire 52 exits the wire insertion hole 41h and extends upward through the second section S2. The upper end face of the wire end 55 (the end face on the side to which the first wire 52 is connected) contacts the lower end face of the wire end support portion 41f, thereby restricting upward movement of the wire end 55 with respect to the shoe base 41 ( When the wire end 55 is pulled upward, the force is transmitted to the shoe base 41).

The wire end 55 has a large-diameter flange near the lower end, and a compression spring 56 is inserted between the flange and the wire end support portion 41f. The wire end 55 is urged downward against the shoe base 41 by the compression spring 56, and the slack in the first wire 52 is removed by this urging force.

The second wire 53 is inserted into the wire insertion hole 41i of the wire end support portion 41g, and the wire end 57 to which the end portion of the second wire 53 is connected is positioned above the wire end support portion 41g. The second wire 53 exits the wire insertion hole 41i and extends downward through the second section S2. The lower end surface of the wire end 57 (the end surface on the side to which the second wire 53 is connected) contacts the upper end surface of the wire end support portion 41g, thereby restricting downward movement of the wire end 57 with respect to the shoe base 42 ( When the wire end 57 is pulled downward, the force is transmitted to the shoe base 41).

The wire end 57 has a large-diameter flange near its upper end, and a compression spring 58 is inserted between the flange and the wire end support portion 41g. The wire end 57 is urged upward against the shoe base 41 by the compression spring 58, and the slack in the second wire 53 is removed by this urging force.

A first section S1 into which the shoes 43 and 44 are inserted and a second section S2 in which the wire end support portions 41f and 41g of the shoe bases 41 and 42 are arranged are arranged on the outside of the vehicle with respect to the inner side wall 31a of the guide rail 31. positioned. On the other hand, the motor unit 50 is attached to the inner side surface of the inner side wall 31 a of the guide rail 31 in the inner space of the door panel below the beltline reinforcement 16 .

As shown in FIG. 8, the motor unit 50 includes a drive section 50a having a motor M, a reduction gear mechanism, etc., and a drum housing 50b that rotatably accommodates the winding drum 51 therein. A notch through which the first wire 52 and the second wire 53 extending from the winding drum 51 are passed is formed in the peripheral surface of the drum housing 50b. When the driving portion 50 a and the drum housing 50 b are combined, the driving shaft 50 c of the driving portion 50 a is connected to the shaft hole of the winding drum 51 so that the driving force of the motor M is transmitted to the winding drum 51 .

The motor unit 50 is fixed to the guide rail 31 by bringing upper and lower brackets 50d and 50e provided on the drum housing 50b into contact with the surface of the vehicle interior side wall 31a on the vehicle interior side and bolting the contact portions. . When the motor unit 50 is fixed, the center of rotation of the winding drum 51 (the axis of the drive shaft 50c) faces the inner and outer circumference directions.

A through hole 31h is formed in the vehicle interior side wall 31a of the guide rail 31 between the fastening positions of the brackets 50d and 50e in the vertical direction (see FIGS. 8 and 22). 31 h of through-holes are provided in the area|region which forms 2nd division S2 (area|region near the outer peripheral side in an inner peripheral direction) among the vehicle interior side walls 31a.

A wire guide member 60 and a wire guide member 61 are attached to the inner side wall 31a of the guide rail 31 at a position slightly above the through hole 31h. The wire guide member 60 and the wire guide member 61 are fixed to the vehicle interior side wall 31a with the bracket 50d of the drum housing 50b using bolts 70. As shown in FIG.

The wire guide member 60 is fixed to the inside of the bracket 50d in an overlapping manner, and the wire guide member 60 and the bracket 50d are formed with through-holes through which the bolts 70 are inserted. The wire guide member 61 is positioned in the second section S2 of the guide rail 31 and is fixed in contact with the surface of the vehicle inner side wall 31a on the vehicle outer side. The wire guide member 61 is formed with a screw hole facing the inside of the vehicle, and a through hole communicating with the screw hole is formed in the inside wall 31a of the vehicle. The threaded portions of the bolts 70 are inserted into the respective through holes of the wire guide member 60 , the bracket 50 d and the vehicle inner side wall 31 a from the inside of the vehicle, and the threaded portions are screwed into the threaded holes of the wire guide member 61 . The tip of the screw portion of the bolt 70 in the fixed state is located inside the screw hole of the wire guide member 61 and is not exposed inside the second section S2 of the guide rail 31 (see FIG. 22). That is, the bolt 70 does not interfere with the wire end support portions 41f, 41f of the shoe base 41 and the wires 52, 53 passing through the second section S2.

The wire guide member 60 is provided with an arm portion 60a extending upward from the fastening position of the bolt 70 . The upper end of the arm portion 60a is fixed to the guide rail 31 by a bolt different from the bolt 70. As shown in FIG. A guide groove 60b extending in the vertical direction is formed in the arm portion 60a. The guide groove 60b is a bottomed groove that is open toward the outside of the vehicle, and faces the surface of the inside wall 31a of the guide rail 31 on the inside of the vehicle with a predetermined gap therebetween (see FIG. 22).

As shown in FIG. 22, the wire guide member 61 is formed with a guide groove 61a extending in the vertical direction. The guide groove 61a is a bottomed groove that opens toward the outside of the vehicle. A stopper surface 61 b is formed at the upper end of the wire guide member 61 . When the shoe base 41 moves downward within the second section S2 of the guide rail 31, the lower end surface of the lower wire end support portion 41g comes into contact with the stopper surface 61b, preventing further downward movement of the shoe base 41. regulated (see FIG. 24). This abutment determines the downward movement end (bottom dead center) of the window glass W supported by the shoe base 41 .

A lower bracket 50 e of the drum housing 50 b is fixed to the guide rail 31 via bolts 71 and nuts 72 . The bolt 71 is threaded from the outside of the vehicle into a through hole formed in the bottom of the second section S2 of the vehicle interior side wall 31a and a through hole formed in the bracket 50d, and screwed into the nut 72. As shown in FIG. The head of the bolt 71 is positioned within the second section S2. The fastening position of the bolt 71 is below the winding drum 51 in the drum housing 50b. Therefore, the wire end support portions 41f and 41f of the shoe base 41 and the wires 52 and 53 passing through the second section S2 do not reach the head of the bolt 71, and interference with the bolt 71 does not occur. There is no possibility that it will occur (see FIG. 22).

In the vicinity of the upper end of the guide rail 31, a pulley bracket 62 is bolted to the inner surface of the inner side wall 31a. A guide pulley 54 is rotatably supported by a pulley bracket 62 via a pulley pin 62a. The guide pulley 54 is a disk-shaped member having an annular wire guide groove formed on its outer periphery. facing inward and outward.

As shown in FIG. 8, the guide rail 31 is formed with a through-hole 31i penetrating through the vehicle inner side wall 31a near the mounting position of the pulley bracket 62. As shown in FIG. The through-hole 31i is provided in a region forming the second section S2 of the vehicle interior side wall 31a (a region closer to the outer periphery in the inner and outer peripheral directions). are in communication. As shown in FIG. 16, the pulley pin 62a is positioned in the third section S3, and the guide pulley 54 directs the radial direction orthogonal to the axis of the pulley pin 62a toward the vehicle interior and exterior, and the second section S2 and the second section S2 through the through hole 31i. It is arranged over 3 divisions S3.

At the door corner portion 10d to which the guide pulley 54 is attached, the guide rail 31 and the connection member 35 are combined. The guide pulley 54 and the pulley bracket 62 are arranged so as to be accommodated in a space surrounded by the inner side wall 35e, the inner peripheral side wall 35f, and the outer peripheral side wall 35g of the second frame portion 35b of the connecting member 35. not exposed to

More specifically, the pulley bracket 62 is elongated in the vertical direction (see FIGS. 6, 8, and 22 to 24), and when viewed from above (or when viewed in cross section perpendicular to the longitudinal direction), it has a plate-like shape extending in and out of the vehicle. and a pair of upper and lower support seats 62c and 62d extending outward from the outer end of the pulley support portion 62b (see FIGS. 17 and 18). ). The support seat 62 c and the support seat 62 d abut on the inner side surface of the inner side wall 31 a of the guide rail 31 . The support seat 62c and the support seat 62d are vertically spaced apart, and a through hole 31i is formed in the vehicle interior side wall 31a between the positions where the support seat 62c and the support seat 62d abut. The pulley pin 62a is supported by the pulley support portion 62b at a vertical position between the support seat 62c and the support seat 62d (see FIG. 6).

18 where the support seat 62c on the upper side of the pulley bracket 62 is attached to the guide rail 31, the thick portion 35m of the connecting member 35 is arranged on the inner side of the inner side wall 31a, and the recessed portion 35n is formed in the thick portion 35m. and a screw hole 35p are formed. The support seat 62c is sandwiched between the vehicle interior side wall 31a and the thick portion 35m and positioned in the escape recess 35n, and the surface facing the vehicle interior abuts the thick portion 35m. Through holes communicating with the screw holes 35p are formed in the support seat 62c and the vehicle interior side wall 31a, respectively. The threaded portion of the bolt 73 is inserted into these through holes from the outside of the vehicle toward the inside of the vehicle and is screwed into the screw hole 35p. The head of the bolt 73 is located in the second section S2 of the guide rail 31, and is tightened until the head abuts the surface of the vehicle interior side wall 31a on the exterior side of the vehicle with a predetermined pressure. As a result, the support seat 62c is sandwiched and fixed between the inner side wall 31a and the thick portion 35m.

That is, the thick portion 35m provided inside the second frame portion 35b (third section S3) of the connecting member 35 is used as a support seat surface, and the pulley bracket is formed by recessing a screw hole 35p on the support seat surface. 62 constitutes a mounting portion for mounting the support seat 62c. This mounting portion has a structure in which the support seat 62c is supported by the thick portion 35m having high rigidity, and the bolt 73 is screwed into the screw hole 35p formed in the thick portion 35m. Excellent strength. In addition, since the bolt 73 is directly screwed into the connecting member 35, workability of assembling the parts inside the door corner portion 10d having a complicated shape is excellent.

6 and 23, the support seat 62c is fixed using two bolts 73. As shown in FIG. The upper bolt 73 is screwed into the screw hole 35p of the connecting member 35 as described above. The threaded portion of the lower bolt 73 is inserted into the space below the thick portion 35m (internal space of the second frame portion 35b of the connecting member 35) through the through holes of the support seat 62c and the inner side wall 31a. It is screwed onto the nut 77 .

At the position where the pulley bracket 62 is fastened by the upper bolt 73 (FIG. 18), the pulley support portion 62b and the support seat 62c are positioned within the relief recess 35n, and the pulley bracket 62 does not interfere with the thick portion 35m. It is not exposed to the appearance of the vertical pillar sash 12 either.

Further, the fastening position of the pulley bracket 62 by each bolt 73 is above the guide pulley 54 . Therefore, the wire end support portions 41f and 41f of the shoe base 41 and the wires 52 and 53 passing through the second section S2 do not reach the head positions of the bolts 73 and interfere with the bolts 73. is unlikely to occur.

17 where the lower support seat 62d of the pulley bracket 62 is attached to the guide rail 31, the connecting member 35 does not have the thick portion 35m, and the third section S3 is widened in the vehicle interior and exterior directions. there is A nut 75, which is separate from the connecting member 35, is arranged in the third section S3, and a bolt 74 screwed onto the nut 75 is used to fasten the support seat 62d and the guide rail 31 together. Through holes communicating with the screw holes of the nut 75 are formed in the support seat 62d and the vehicle interior side wall 31a, respectively. The threaded portion of the bolt 74 is inserted and screwed into the threaded hole of the nut 75 . The bolt 74 is tightened until its head contacts the surface of the vehicle interior side wall 31a on the vehicle exterior side with a predetermined pressure.

At the fastening position of the pulley bracket 62 by the bolt 74, the pulley support portion 62b, the support seat 62d and the nut 75 are accommodated in the third section S3, and the pulley bracket 62 and the nut 75 are not exposed to the outside. Further, since the bolt 74 is a countersunk screw whose head hardly protrudes outward from the vehicle interior side wall 31a, the wire end support portions 41f and 41f of the shoe base 41 passing through the second section S2 and the wire ends 41f and 41f pass through the second section S2. 52 and 53 do not interfere with the head of bolt 74 .

The guide pulley 54 assembled to the guide rail 31 (and the connecting member 35) via the pulley bracket 62 as described above can be passed through by setting the direction of the axis of the pulley pin 62a, which is the center of rotation, in the inner and outer peripheral directions. It is arranged over the second section S2 and the third section S3 through the hole 31i (see FIG. 16). As a result, the first wire 52 is guided through the guide pulley 54 to the wire end support portion 41f of the shoe base 41 located in the second section S2 and the winding drum 51 located below the third section S3. be able to.

The frame portion 30a of the inner sash 30 and the second frame portion 35b of the connection member 35 in the vertical pillar sash 12 have a depth in the vehicle interior and exterior direction greater than a width in the inner and outer peripheral directions (Figs. 9, 14 to 14). 17). The guide pulley 54 has a flat shape in which the diameter is larger than the thickness in the axial direction, and is arranged across the second section S2 and the third section S3 in the second frame portion 35b so that the diameter direction is oriented in the vehicle interior and exterior direction. By doing so, it can be housed inside the connection member 35 with good space efficiency.

As shown in FIGS. 16 and 17, in the portion where the connection member 35 is provided, the presence of the thick inner peripheral side wall 35f causes the inner peripheral region of the third section S3 (the vehicle body of the first section S1 to inner region) is slightly narrowed. However, the area near the outer periphery of the third section S3 (the area inside the vehicle of the second section S2) is about the same width as the portion where the inner sash 30 is provided (see FIGS. 9, 14 and 15). The sturdiness is preserved. Therefore, by arranging the guide pulley 54 in the position of the region near the outer periphery in the third section S3, the guide pulley 54 can be moved to the third section S3 while using the large-diameter guide pulley 54 whose outer periphery is positioned close to the inner side wall 35e. 2 can be accommodated within the frame portion 35b. In other words, while realizing the guidance of the first wire 52 over the second section S2 and the third section S3 straddling the vehicle inner side wall 31a of the guide rail 31, A guide pulley 54 of class size can be used. The larger the diameter (curvature radius) of the guide pulley 54, the gentler the curve of the guided first wire 52, which is advantageous in terms of resistance reduction and smooth operation when the window regulator 40 is driven.

As shown in FIGS. 8 and 22, the guide rail 31 further includes a vertical position between the position where the motor unit 50 is attached and the position where the guide pulley 54 (pulley bracket 62) is attached (the guide pulley 54 and the winding bracket 62). A wire pressing member 63 is attached at approximately the same distance from the drum 51 . The wire pressing member 63 is provided in a general cross-sectional portion where the inner sash 30 and the guide rail 31 constitute the vertical pillar sash 12, and the inside of the third section S3 (inside the second section S2). ), the wire pressing member 63 is accommodated (see FIG. 14).

The wire pressing member 63 is brought into contact with the inner surface of the inner side wall 31a of the guide rail 31 and fixed by bolting. The wire holding member 63 is formed with a screw hole toward the outside of the vehicle, and a through hole communicating with the screw hole of the wire holding member 63 is formed in the area of the inside wall 31a of the guide rail 31 forming the second section S2. A hole is formed. The wire pressing member 63 is fixed to the guide rail 31 by inserting the threaded portion of the bolt 76 into the through hole from the outside of the vehicle and screwing it into the threaded hole of the wire pressing member 63 (see FIG. 23). Four bolts 76 are used at different positions in the vertical direction. Since each bolt 76 is a countersunk head screw whose head hardly protrudes outward from the vehicle interior side wall 31a, the wire end support portions 41f and 41f of the shoe base 41 and the wires 52 and 53 passing through the second section S2 are prevented. does not interfere with the head of each bolt 76 (see FIG. 14).

The wire pressing member 63 has its longitudinal direction oriented in the vertical direction, and is formed with a guide groove 63a extending in the vertical direction. As shown in FIG. 23, the guide groove 63a is a bottomed groove that is open toward the outside of the vehicle.

In the window regulator 40, each wire 52, 53 is routed as follows. As a premise, the door 10 has a curved outer surface shape that is convex toward the outside of the vehicle. The upper and lower ends have a curved shape protruding toward the outside of the vehicle (see FIG. 4).

In the winding drum 51, the position (indicated as winding start point P1 in FIG. 22) where the winding (pulling) of the second wire 53 around the helical groove is started is the rotational center of the drive shaft 50c. set outside. As shown in FIG. 22, the second wire 53 extends obliquely upward from the winding start point P1 and is led through the through hole 31h of the guide rail 31 into the second section S2. The second wire 53 entering the second section S2 is inserted into the guide groove 61a of the wire guide member 61 positioned slightly above the through hole 31h. Both side surfaces of the guide groove 61a restrict deflection of the second wire 53 in the inner and outer peripheral directions.

The bottom surface of the guide groove 61a of the wire guide member 61 is a curved surface that is convex toward the outside of the vehicle, and has a larger curvature than the inside wall 31a of the vehicle. If the second wire 53 passing through the through-hole 31h of the guide rail 31 is allowed to run along the vehicle interior side wall 31a as it is without using the wire guide member 61, the edge portion (especially the upper edge portion) of the through-hole 31h The second wire 53 may be rubbed and damaged. By supporting the second wire 53 on the bottom surface of the guide groove 61a and passing the second wire 53 through a position spaced apart from the inner side wall 31a toward the outer side of the vehicle, it is possible to prevent the second wire 53 from rubbing against the edge portion of the through hole 31h. prevent.

When the position of the bottom surface of the guide groove 61a with respect to the vehicle inner side wall 31a is lowered (closer to the vehicle interior), the approach angle of the second wire 53 from the winding drum 51 side with respect to the through hole 31h becomes smaller, and the second wire 53 moves along a smooth trajectory. It can lead to section S2. On the other hand, the second wire 53 tends to rub against the edge portion of the through hole 31h. If the position of the bottom surface of the guide groove 61a relative to the inner side wall 31a is raised (closer to the outer side of the vehicle), the angle of entry of the second wire 53 from the winding drum 51 side into the through hole 31h increases. Contact of the second wire 53 is less likely to occur. On the other hand, the degree of bending of the second wire 53 in the second section S2 increases, which may lead to increased resistance during driving. Considering these conditions, the second wire 53 is smoothly guided from the winding start point P1 of the winding drum 51 to the second section S2, and the second wire 53 rubs against the edge portion of the through hole 31h. The position of the bottom surface of the guide groove 61a is set so as to have an optimal height that is not

Above the wire guide member 61, the second wire 53 extends along the vehicle-outside surface (bottom surface of the second section S2) of the vehicle-interior side wall 31a of the guide rail 31 (see FIGS. 9 and 22). Since the surface of the vehicle interior side wall 31a on the vehicle exterior side is a smooth surface that is convexly curved toward the vehicle exterior side, the second wire 53 is smoothly guided without being caught or the like.

The second wire 53 is inserted into the wire insertion hole 41i of the wire end support portion 41g and connected to the shoe base 41 via the wire end 57 (see FIG. 21). Note that the wire insertion hole 41i of the wire end support portion 41g is a hole with a closed cross-sectional shape that does not have a slit that opens to the side. Therefore, during assembly, the second wire 53 is first inserted into the wire insertion hole 41i (inserting the end opposite to the wire end 57), and then the second wire 53 is wound around the winding drum 51. It is preferred to make turns and connections.

In the winding drum 51, the position (indicated as winding start point P2 in FIG. 22) where the winding (pulling) of the first wire 52 around the helical groove is started is the rotational center of the drive shaft 50c. set inside. As shown in FIG. 22, the first wire 52 extends upward from the winding start point P2. The first wire 52 extending upward from the winding drum 51 is inserted into the guide groove 60 b of the wire guide member 60 . Both side surfaces of the guide groove 60b restrict deflection of the first wire 52 in the inner and outer peripheral directions.

The bottom surface of the guide groove 60b of the wire guide member 60 is a curved surface that is convex toward the outside of the vehicle, and has a larger curvature than the inside wall 31a of the vehicle. When not held by the wire guide member 60, the trajectory of the first wire 52 connects the winding drum 51 and the guide pulley 54 at the shortest distance on the concave side (vehicle inner side) of the guide rail 31, which is shaped to be convex outward from the vehicle. becomes. This virtual wire trajectory is shown in FIG. 22 as a wire short circuit trajectory 52x. The bottom surface of the guide groove 60b supports the first wire 52 in a state of being pushed toward the outside of the vehicle with respect to the wire short-circuit locus 52x.

As shown in FIG. 22, the first wire 52 is further supported by a wire pressing member 63 at an intermediate position between the winding drum 51 and the guide pulley 54 in the vertical direction. Both side surfaces of the guide groove 63a of the wire pressing member 63 restrict deflection of the first wire 52 in the inner and outer peripheral directions.

The bottom surface of the guide groove 63a of the wire pressing member 63 is a curved surface convex toward the outside of the vehicle, and has a larger curvature than the inside wall 31a of the vehicle. The bottom surface of the guide groove 63a has a smaller distance from the inner side wall 31a of the guide rail 31 than the bottom surface of the guide groove 60b of the wire guide member 60 (see FIG. 22), and the first wire held by the bottom surface of the guide groove 60b 52 is further pushed into the outside of the vehicle.

The first wire 52, whose trajectory has been changed from the wire short-circuit trajectory 52x by the wire guide member 60 and the wire pressing member 63, is positioned at an appropriate distance from the inner side surface of the inner side wall 31a of the guide rail 31, which is curved in a concave shape. It is routed in the up-down direction while maintaining (a position to be accommodated in the third section S3).

Inside the door panel 10a where the guide rail 31 is exposed without being covered with the inner sash 30, the first wire 52 extends vertically while maintaining a predetermined distance from the inner side wall 31a of the guide rail 31. extended.

In the general cross section of the vertical column sash 12 above the beltline reinforcement 16, the first wire 52 passes through the third section S3 surrounded by the frame portion 30a of the inner sash 30 and the inner side wall 31a of the guide rail 31. (See Figure 9). The wire pressing member 63 is accommodated in the third section S3 in the general cross section, and reliably guides the first wire 52 (see FIG. 14). Even in the door corner portion 10d where the connection member 35 is provided instead of the frame portion 30a of the inner sash 30, the first wire 52 continues to pass through the third section S3 surrounded by the second frame portion 35b and the vehicle interior side wall 31a ( See Figure 17).

The first wire 52 that has reached near the upper end of the guide rail 31 is wound around the wire guide groove on the outer circumference of the guide pulley 54 . As described above, the guide pulley 54 is provided at a position straddling the second section S2 and the third section S3 through the through hole 31i of the guide rail 31. As shown in FIG. Therefore, the first wire 52, which extends upward on the side of the third section S3 and is guided to the guide pulley 54, reverses its extending direction along the wire guide groove of the guide pulley 54, and moves downward in the second section S2. head to In other words, one end and the other end of the winding region of the first wire 52 with respect to the wire guide groove of the guide pulley 54 (the winding start point Q1 and the winding start point Q2 shown in FIGS. 16 and 23) are the pulley pins 62a. are arranged in the second section S2 and the third section S3 in a substantially symmetrical positional relationship with respect to .

The first wire 52 extending downward from the winding start point Q2 of the guide pulley 54 is inserted into the wire insertion hole 41h of the wire end support portion 41f in the second section S2, and is attached to the shoe base 41 via the wire end 55. are connected (see FIG. 21). The wire insertion hole 41h of the wire end support portion 41f is a hole with a closed cross-sectional shape that does not have a slit that opens sideways. Therefore, at the time of assembly, the first wire 52 is first inserted into the wire insertion hole 41h (the end opposite to the wire end 55 is inserted), and then the first wire 52 is inserted into the guide pulley 54 and the winding drum 51. Winding and connecting wires 52 is preferred.

When the first wire 52 and the second wire 53 are routed as described above, the compression springs 56 and 58 press the wire ends 55 and 57 toward each other, so that the wires 52 and 53 A certain amount of tension is applied. As a result, the slider 45 to which the wires 52 and 53 are connected is stabilized, and the window glass W whose position is controlled via the slider 45 is held and moved up and down with high accuracy.

As shown in FIG. 21, the shoe base 41 accommodates 56, 57 and compression springs 56, 58 between the wire end support portions 41f and 41g. Only the opposing end surface portions of the two wire end support portions 41f and 41f (surfaces where the end surfaces of the wire end 55 and the wire end 57 abut) form this accommodating portion. There are no side walls or the like surrounding the sides. Therefore, the wire connection structure is established with a very compact and simple configuration.

As shown in FIG. 21, each of the wire end supporting portions 41f and 41f has a length in the vertical direction greater than the width of the end face with which the wire ends 55 and 57 abut. That is, the support length of each wire 52, 53 by the wire insertion holes 41h, 41h is increased. When the straightness of the wires 52 and 53 is maintained by the wire insertion holes 41h and 41h having a long support length, the effect of suppressing the sideways deflection of the wire ends 55 and 57 located in the immediate vicinity can be obtained.

In addition, when the wire end support portions 41f, 41f are inserted into the second section S2 of the guide rail 31, the inner surfaces of the second section S2 (vehicle inner side wall 31a, outer peripheral side wall 31c, cover wall 31e, partition wall 31f) are positioned so that the wire ends 55 , 57 to suppress vibration. As shown in FIG. 17, there is a clearance of a predetermined size between the inner surface of the second section S2 and the wire ends 55 (or wire ends 57). do not have. However, the inner surface of the second section S2 can prevent the wire ends 55, 57 from excessively deviating from the extended upper positions of the wire end support portions 41f, 41f.

From the above, as a wire connection structure in the shoe base 41, there is a minimum configuration (driving force transmission portion) in which the end surfaces of the wire ends 55 and 57 are brought into contact with each other in the extending direction of the wires 52 and 53 to receive the traction force. Enough. In particular, in the window regulator 40 of this embodiment, most of the lift mechanism except for the motor unit 50 is accommodated in the inner space of the vertical pillar sash 12 which is elongated in the vertical direction. Therefore, it is extremely effective in terms of space efficiency to complete the wire connection structure in the elongated space between the facing surfaces of the wire end support portions 41f, 41f that are spaced apart in the vertical direction. Specifically, the cross-sectional area of the second section S2 in which the wire end support portions 41f, 41f are housed can be small. Therefore, the first section S1 into which the shoes 43 and 44 are inserted and the second section S2 into which the wires 52 and 53 are inserted can be arranged in parallel without increasing the width of the frame portion 30a in the inner and outer peripheral directions. is possible. In addition, since the second section S2 is compact in the vehicle interior and exterior directions, the second section S2 and the third section S3 through which the wires 52 and 53 are inserted are separated from the window glass W by the vehicle interior side wall 30d of the frame portion 30a ( They can be arranged side by side within a restricted dimension of the depth up to the vehicle interior side wall 35e) of the second frame portion 35b.

When assembling the window regulator 40, it is preferable from the standpoint of workability to work with the wires 52 and 53 loosened and to apply the final tension to the wires 52 and 53 at as late a stage as possible. . In the manufacture of the window regulator 40 of the present embodiment, the wires 52 and 53 are tensioned by attaching the wire pressing member 63 after performing a series of parts assembly and wire routing. As described above, the wire pressing member 63 is located on the concave side (vehicle inner side) of the curved guide rail 31 and on the vehicle outer side (vehicle inner side) of the wire short-circuit locus 52x connecting the winding drum 51 and the guide pulley 54 at the shortest distance. inside the recess) to support the first wire 52 . That is, the tension of the first wire 52 is increased by changing the wiring locus of the first wire 52 toward the outside of the vehicle and making the actual locus of the first wire 52 longer than the wire short-circuit locus 52x. .

Note that the first wire 52 is also supported by the wire guide member 60 in addition to the wire pressing member 63 on the concave side (vehicle inner side) of the guide rail 31 . Therefore, even if the wire pressing member 63 is not attached, a certain amount of tension is applied to the wires 52 and 53 when the wire guide member 60 is attached. If the wires 52 and 53 are too loose, the wires 52 and 53 are likely to come off the guide pulley 54, and the assembly becomes difficult. can proceed with the work. When the wire pressing member 63 is assembled in the final stage, the first wire 52, which is supported in advance by the wire guide member 60, only needs to be slightly pressed.

The wire pressing member 63 is accommodated in the third section S3 in the completed state of the standing pillar sash 12 (see FIG. 14). Therefore, before combining the guide rail 31 with the inner sash 30 and the connection member 35, the assembly of each part of the window regulator 40 including the wire pressing member 63 is completed. FIG. 19 shows the regulator assembly 40A in this state. The regulator assembly 40A has already been completed as a functional part for moving (lifting) the window glass W along the guide rails 31. As shown in FIG. Therefore, it is possible to perform operation check, inspection, shipping (sales), maintenance, etc. in the state of the regulator assembly 40A.

Note that the connecting member 35 is not attached to the regulator assembly 40A shown in FIG. Therefore, the upper bolt 73 (see FIGS. 18 and 23) of the pair of bolts 73 for fastening the support seat 62c of the pulley bracket 62 is not fixed to the screw hole 35p of the connecting member 35. As shown in FIG. However, the lower bolt 73 is screwed into the nut 77, and the support seat 62c is fixed to the guide rail 31 and is stable.

FIGS. 20, 23 and 24 show states in which the window glass W is raised and lowered by the window regulator 40 having the above configuration. The solid line in FIG. 20 shows the fully closed position (top dead center) where the window glass W is raised to the maximum, and the two-dot chain line in FIG. position (bottom dead center). 23 shows the state of the window regulator 40 when the window glass W is fully open, and FIG. 24 shows the state of the window regulator 40 when the window glass W is fully open.

At the fully closed position of the window glass W, the shoe 43 of the upper slider 45 reaches near the upper end of the guide rail 31, as shown in FIG. A guide pulley 54 is provided near the upper end of the guide rail 31. A first section S1 in which the shoe 43 is inserted and a second section S2 in which the guide pulley 54 is arranged are arranged in parallel in the inner and outer peripheral directions. Since they are separated from each other, the shoe 43 and the guide pulley 54 do not interfere with each other.

In the fully closed position of the window glass W, as shown in FIG. 23, the upper wire end support portion 41f provided on the slider 45 is positioned directly below the guide pulley 54 (winding start point Q1). In the slider 45, the wire end support portion 41f is provided so as to be displaced downward with respect to the shoe 43 (shoe support portion 41c) (see FIG. 21). Therefore, the wire end support portion 41f can be positioned directly below the guide pulley 54 in the state where the shoe 43 reaches the position parallel to the guide pulley 54 as described above. That is, each element of the drive system can be housed in the vicinity of the upper end of the guide rail 31 with good space efficiency without impairing the smooth routing of the first wire 52 around the guide pulley 54 .

Furthermore, the upper part of the upper slider 45 is located near the upper end of the vertical column sash 12 (door corner part 10d), and the lower part of the lower slider 46 is located near the beltline reinforcement 16 (see FIG. 1), The window glass W is supported over substantially the entire area of the vertical pillar sash 12 in the vertical direction. As a result, the window glass W can be stably supported with extremely high precision, and the resistance to falling of the window glass W in the vehicle longitudinal direction and the vehicle interior and exterior directions can be improved.

As shown in FIG. 24, when the window glass W is fully opened, the lower end surface of the wire end support portion 41g on the lower side of the shoe base 41 constituting the slider 45 abuts against the stopper surface 61b of the wire guide member 61. Then, further lowering of the window glass W is restricted. That is, the wire guide member 61 also functions as a mechanical stopper that determines the downward movement end of the window regulator 40 .

Even in the fully open position, the window glass W is supported over a wide range in the vertical direction within the door panel 10a relative to the guide rails 31, so that the window glass W can be supported with high accuracy and stability as in the case of the fully closed position. be done.

As described above, in the door 10 of the present embodiment, the upright sash 12 incorporates components of the elevating mechanism for transmitting the driving force of the motor M, which is the driving source, to the window glass W in the window regulator 40 . As a result, the space efficiency and layout around the door panel 10a can be improved compared to the existing configuration in which the window regulator is arranged in the inner space of the door panel 10a below the window opening 10c. For example, the degree of freedom in setting the shape of the door trim on the inner side of the door is increased. In addition, the inner surface of the door can be made closer to the outside of the vehicle to improve foot handling when getting in and out of the vehicle. Alternatively, the interior space of the door panel 10a can be widened to secure a space for arranging functional parts other than the window regulator, or to improve the ease of assembly of parts into the door panel 10a.

26 and 27 show the window regulator 140 of the second embodiment. While the window regulator 40 of the previous embodiment has a wire type transmission mechanism, this window regulator 140 has a rack and pinion type transmission mechanism. The rest of the configuration is the same as in the previous embodiment, and the common parts are denoted by the same reference numerals as in the previous embodiment, and the description thereof is omitted.

As shown in FIG. 26, the motor unit 150 that constitutes the window regulator 140 is attached to the guide rail 31 at substantially the same position (that is, inside the door panel 10a) as the motor unit 50 of the previous embodiment. The motor unit 150 includes a drive section 150a having a motor M and a pinion support member 150b that rotatably supports the pinion 90. As shown in FIG. The pinion 90 is connected to a drive shaft 150c, and rotational driving force is transmitted from the drive portion 150a through the drive shaft 150c. The pinion support member 150b is fastened and fixed by bringing the upper and lower brackets 150d and 150e into contact with the inner sidewall 31a of the guide rail 31 from the inner side of the vehicle. The pinion 90 supported in this manner is rotationally driven around a drive shaft 150c directed in the inner and outer peripheral directions.

A through hole 31j is formed in the vehicle interior side wall 31a of the guide rail 31 between positions at which the upper and lower brackets 150d and 150e of the pinion support member 150b are fixed. The through hole 31j is formed at a position that allows communication between the second section S2 and the third section S3 (see FIG. 27) in the pillar sash 12. As shown in FIG. Part of the pinion 90 enters the second section S2 through the through hole 31j. FIG. 27 shows a general cross-sectional position of the vertical column sash 12 above the position of the pinion 90, and the pinion 90 is virtually represented by a one-dot chain line.

A rack 91 is arranged in the second section S2 in the pillar sash 12 (guide rail 31). The rack 91 is an elongated member that extends along the longitudinal direction of the guide rail 31, and has teeth 91a that are continuously formed in the longitudinal direction facing toward the inside of the vehicle. A rack guide 92 is provided in the second section S2 to allow the rack 91 to move stably in the vertical direction (see FIG. 27).

The shoe base 41 of the slider 45 is provided with a rack connecting portion 41j protruding outward from the connecting portion 41b near the center in the longitudinal direction (below the shoe support portion 41c). The rack connecting portion 41j extends into the second section S2 and is fixed to the vehicle-exterior surface of the rack 91 (the surface on which the tooth portion 91a is not formed). A portion near the upper end of the rack 91 is fixed to the rack connecting portion 41j.

The rack 91 arranged in the second section S2 extends to the formation position of the through hole 31j, and the pinion 90 entering the second section S2 through the through hole 31j meshes with the tooth portion 91a of the rack 91. As shown in FIG. When the pinion 90 rotates forward and backward by the driving force of the motor M, the meshing rack 91 moves vertically. The movement of the rack 91 is transmitted to the slider 45, and the window glass W moves up and down. The rack 91 has a length that meshes with the pinion 90 over the entire movable range from the fully closed position to the fully opened position of the window glass W (see FIG. 20).

As with the window regulator 40 of the previous embodiment, the window regulator 140 incorporates in the upright sash 12 components of an elevating mechanism that transmits the driving force of the motor M, which is the driving source, to the window glass W. In particular, since the transmission portion for transmitting the driving force to the slider 45 is composed only of the pinion 90 and the rack 91, the number of parts is small, which is advantageous in terms of simplicity of construction and ease of production.

28 to 31 show modifications of the elastic cover 33 provided on the pillar sash 12. FIG. 28 to 31 show the shape of the elastic cover 33 in an initial state (free state) in which pressure from the window glass W and the garnish 32 is not applied. When the window glass W is closed in the completed state of the vertical column sash 12, the elastic cover 33 of each modified example is elastically deformed in the same manner as in the state shown in FIG. 28 to 31 show the components of the window regulator 40 of the wire type transmission mechanism, the elastic cover 33 of each modified example is a vertical column sash equipped with the window regulator 140 of the rack and pinion type transmission mechanism.

In the elastic cover 33 of the first modified example shown in FIG. 28, the lip portion 33b is provided with a sub-lip 33m. The sub-lip 33m is a cantilever-shaped projecting portion provided on the vehicle outer side surface 33k side of the lip portion 33b, and extends from the distal end side of the lip portion 33b toward the base end side connected to the hollow portion 33a (that is, from the inner peripheral side to the outer peripheral side). to the side) protrudes.

The sub lip 33m is provided in the same range as a portion of the cover wall 31e in the inner and outer peripheral directions (vehicle front-rear direction). That is, the sub-lip 33m is provided in a region of the lip portion 33b located between the vehicle interior side surface W2 of the window glass W and the cover wall 31e of the guide rail 31 (the region within the gap U2). A vehicle interior portion 33n having a vehicle interior side surface 33j is further present in the region of the lip portion 33b. The thickness of the sub-lip 33m is smaller than that of the inner side portion 33n. The sub-lip 33m and the vehicle interior side portion 33n face each other with a space in the vehicle interior and exterior direction, and a gap 33p is formed between the sub lip 33m and the vehicle interior portion 33n. The gap 33p is a space with an opening facing the outer peripheral side and closed on the inner peripheral side, the vehicle outer side, and the vehicle inner side.

In the configuration shown in FIG. 28, if water enters the gap U2 from between the edge surface W3 of the window glass W and the hollow portion 33a (especially the inner peripheral side wall 33d) of the elastic cover 33, the gap U2 opens toward the outer periphery. Water enters the gap 33p. The hydraulic pressure of the water entering the gap 33p acts to press the sub-lip 33m toward the vehicle outer side and the vehicle inner side portion 33n toward the vehicle inner side. As a result, the sub lip 33m is separated from the vehicle inner side portion 33n (i.e., the vehicle inner side portion 33n) with the base end portion (the portion where the sub lip 33m and the vehicle inner side portion 33n branch off) connected to the main body portion of the lip portion 33b as a fulcrum. outward) elastically deforms. As a result, the degree of contact (contact pressure) between the vehicle outer side surface 33k of the sub lip 33m and the vehicle inner side surface W2 of the window glass W increases. In addition, since the water pressure of the water entering the gap 33p presses the inner side portion 33n toward the cover wall 31e, the degree of contact (contact pressure) between the inner side surface 33j and the cover wall 31e at the inner side portion 33n increases. As a result, the waterproofness of the gap U2 is improved, and water is prevented from entering the inner peripheral side of the gap U2.

The elastic cover 33 of the second modification shown in FIG. 29 has a closed cross-sectional hollow space 33q inside the lip portion 33b. The hollow space 33q is formed in a region positioned within the gap U2 in the inner and outer peripheral directions (vehicle front-rear direction), like the gap 33p of the first modified example (FIG. 28). An exterior thin portion 33r having an exterior side surface 33k is provided on the exterior side of the hollow space 33q, and an interior thin portion 33s having an interior side surface 33j is provided in the interior side of the hollow space 33q.

In the configuration shown in FIG. 29, if water enters the gap U2 from between the edge surface W3 of the window glass W and the hollow portion 33a (especially the inner peripheral side wall 33d) of the elastic cover 33, the water that enters the window glass W and the vehicle-exterior thin-walled portion 33r. Then, a force is applied to press the vehicle-exterior thin portion 33r toward the vehicle interior. The hollow space 33q makes it easier for the vehicle-exterior thin-walled portion 33r to elastically deform toward the vehicle interior.

Here, when the vehicle-exterior thin-walled portion 33r is pressed by water pressure and elastically deforms toward the vehicle-interior side, the reaction force causes the region of the lip portion 33b on the tip side of the vehicle-exterior thin-walled portion 33r to elastically deform outwardly of the vehicle. The degree of adhesion (contact pressure) of the glass W to the vehicle interior side surface W2 increases. As shown in FIG. 29, in the region in the vertical direction of the vehicle where the shoe bases 41 and 42 are located, the region of the lip portion 33b on the tip side of the vehicle outer thin portion 33r is in close contact with the shoe bases 41 and 42. degree (contact pressure) increases. In addition, part of the force that presses the vehicle-exterior thin-walled portion 33r toward the vehicle interior is transmitted to the vehicle-interior thin-walled portion 33s through the peripheral portion of the hollow space 33q, and the vehicle-interior thin-walled portion 33s is pressed toward the cover wall 31e. , the degree of close contact (contact pressure) between the vehicle interior side surface 33j and the cover wall 31e at the vehicle interior thin portion 33s also increases. As a result, water is prevented from entering the inner peripheral side through the gap U2.

In the configuration of FIG. 29, the position where the hollow space 33q is provided in the inner and outer peripheral direction (vehicle front-rear direction) is set closer to the inner peripheral side (closer to the tip of the cover wall 31e) of the gap U2. It is also possible to position the hollow space 33q on the outer peripheral side (closer to the outer peripheral side wall 31c) than the position. In this case, when the vehicle-exterior thin portion 33r is pressed toward the vehicle interior by the water pressure of water that has entered, the region that is pressed toward the vehicle exterior by the reaction force starts from a position on the outer peripheral side of the structure shown in FIG. Become. That is, the water stop point by the lip portion 33b is set closer to the front side of the water infiltration path.

As described above, in each of the modifications shown in FIGS. 28 and 29, the portions (especially, the sub-lip 33m and the vehicle outer thin portion 33r) that are elastically deformed by the water pressure entering the gap U2 and have the effect of enhancing waterproofness are provided. A lip portion 33b of the elastic cover 33 is provided. As can be seen from these modifications, the sealing member (corresponding to the elastic cover 33) of the present invention can be selected from various shapes according to the configuration and shape of the part to be waterproofed to improve waterproofness. .

In the elastic cover 33 of the third modified example shown in FIG. 30, the portion held in the holding recess U1 is not a hollow shape (hollow portion 33a) with a closed cross section, but a partially open hollow portion 33t having an opening 33u. It's becoming Of the partially open hollow portion 33t, the opening 33u is not the inner peripheral side wall 33d that seals with the edge surface W3 of the window glass W or the outer peripheral side wall 33e that seals with the inner peripheral side surface 32e of the garnish 32. , through the inner sidewall 33g located on the inner side of the vehicle. Therefore, sufficient waterproofness can be obtained even with a configuration in which the partially open hollow portion 33t is provided instead of the hollow portion 33a.

In the elastic cover 33 of the fourth modified example shown in FIG. 31, the portion held in the holding recess U1 does not have a hollow shape (hollow portion 33a) with a closed cross section, but a solid portion having no hollow space inside. 33v. The outer surface shape of the solid portion 33v is substantially the same as that of the hollow portion 33a. The solid portion 33v has an elastic deformability corresponding to the material forming the elastic cover 33, and both the edge surface W3 of the window glass W and the inner peripheral side surface 32e of the garnish 32 are elastically deformed in the inner and outer peripheral directions. , and seals the space between the window glass W and the garnish 32 in a watertight manner.

The solid portion 33v has excellent stability in cross-sectional structure. Therefore, similar to the hollow portion 33a, while absorbing variations in component accuracy and assembly accuracy of the peripheral members (inner sash 30, guide rail 31, garnish 32, etc.) of the elastic cover 33, the inside of the holding recess U1 can be maintained with a high degree of stability. can be placed in

As described above, in the door 10 of the above-described embodiment, the frame portion 30a of the inner sash 30 and the guide rail 31 constituting the vertical pillar sash 12 are positioned on the outer side of the vehicle. , the lip portion 33b of the elastic cover 33 seals between the inner side surface W2 of the window glass W and the guide rail 31. As shown in FIG. The guide rail 31 has a cover wall 31e extending inwardly from a position near the edge surface W3 of the window glass W in the inner and outer peripheral directions to face the vehicle interior side surface W2. The simple structure of arranging the lip portion 33b between the cover wall 31e and the vehicle interior side surface W2, which are substantially parallel to each other, can reliably keep the vehicle interior area of the window glass W watertight. The lip portion 33b has a simple cantilevered shape, and if the wall thickness (the distance between the inner side surface 33j and the outer side surface 33k) in the free state is greater than the distance between the cover wall 31e and the inner side surface W2, the lip portion 33b has reliable sealing performance. accuracy control is easy. Note that when there is a gap 33p and a hollow space 33q as shown in FIGS. 28 and 29, the thickness of the lip portion 33b also includes those spaces.

Although the lip portion 33b itself is highly flexible, it is sandwiched between the window glass W and the cover wall 31e in a region having a predetermined extent in the inner and outer peripheral directions, so excessive deformation and irregular deformation are suppressed. . As a result, the lip portion 33b is supported with excellent stability, and high sealing performance can be obtained.

In addition, the lip portion 33b extends to the inner peripheral side from the area (the area where the cover wall 31e is located) that is in close contact with the vehicle interior side surface W2 of the window glass W, and covers most of the guide rail 31 that is open to the vehicle exterior. It also functions as an exterior component that covers the outside of the vehicle. Especially in the door 10, since the components of the window regulators 40 and 140 are arranged inside the pillar sash 12 including the guide rail 31, it is aesthetically pleasing to cover the internal structure of the pillar sash 12 with the lip portion 33b so that it cannot be seen. valid above.

Since the tip of the lip portion 33b of the above embodiment is brought into contact with the movable sliders 45 and 46, a certain region from the tip is configured to have a high degree of freedom of deformation. Unlike this, it is also possible to employ a configuration in which the lip portion 33b does not contact the sliders 45 and 46. FIG. For example, a configuration in which the components of the window regulators 40 and 140 including the sliders 45 and 46 are not accommodated within the pillar sash 12 may be employed. In this case, it is also possible to extend the cover wall 31e to the inner peripheral side than in the above embodiment so that the tip of the lip portion 33b is sandwiched between the window glass W and the cover wall 31e.

The elastic cover 33 has a hollow portion 33a in addition to the lip portion 33b. As a result, the window glass W is continuously sealed from the vehicle interior side surface W2 to the edge surface W3, and a higher sealing performance can be obtained. As for the part where the edge surface W3 of the window glass W is sealed, by forming the hollow part 33a having a hollow shape with a closed cross section, both high shape stability and excellent error absorption can be achieved. It is also possible to employ a shape other than a hollow shape, such as a modified example (a partially open hollow portion 33t in FIG. 30 and a solid portion 33v in FIG. 31).

In the above-described embodiment, it is the garnish 32 that constitutes the pillar sash 12 that the outer peripheral side portion (outer peripheral side wall 33e, outer peripheral protruding wall 33f) of the hollow portion 33a of the elastic cover 33 abuts. It is possible.

For example, instead of providing an exterior member such as the garnish 32, the design portion 30b of the inner sash 30, which constitutes the main body portion of the pillar sash 12, is set at a position substantially flush with the outer side surface W1 of the window glass W (as shown in the figure). The design portion 30b may be protruded to the outside of the vehicle from the position). In this case, the hollow portion 33a is sandwiched between the edge surface W3 of the window glass W and the design portion 30b in the inner and outer peripheral directions.

Further, as a different form, the hollow portion 33a (or the partially open hollow portion 33t, or the solid portion 33v) may contact the edge of the door opening of the vehicle body to which the door 10 is attached instead of the pillar sash 12. To establish. In this case, a body pillar (center pillar) constituting the vehicle body is arranged at a position corresponding to the garnish 32 and the design portion 30b shown in FIG. The open hollow portion 33t and the solid portion 33v) are sandwiched between the window glass W and the body pillar in the inner and outer peripheral directions.

In the door sash 10b of the above embodiment, the upper sash 11 and the vertical pillar sash 12 are connected by the connecting member 35 at the door corner portion 10d, but the upper sash and the vertical pillar sash are directly joined at the door corner portion. can also be applied to door sashes.

The door 10 of the above-described embodiment is a door (sash door) of a type in which a frame-shaped door sash 10b configured by a member separate from the door panel 10a is provided above the door panel 10a. can also be applied to For example, a type of door in which the door panel and the door sash are integrally formed (an inner full door in which the inner panel and the door sash are integrally formed, and an inner panel and an outer panel in which the inner and outer sides of the door sash are integrally formed and then combined) It can also be applied to panel doors). That is, any vehicle door including a door sash is applicable, regardless of whether it is integrated with the door panel or separate.

Moreover, although the above embodiment is applied as a sealing structure along the vertical pillar sash 12, it is also possible to apply it as a sealing structure along the front sash 13. Alternatively, in the case of a vehicle door provided with a division bar that separates a window opening that is opened and closed by a window glass that moves up and down from a fixed window frame that is closed by a fixed window, it can be applied as a sealing structure along the division bar. . That is, these front sashes and division bars are also included in the door sashes targeted by the present invention.

Although the above embodiment is applied to the door 10 of the type in which the window glass W moves up and down, the direction in which the window glass moves when opening and closing is not limited to this. For example, it can be applied to a door whose window glass slides laterally (horizontally). More specifically, if the extending direction of the guide rail 31 in the above embodiment is replaced with the horizontal direction instead of the vertical direction, the seal structure of the vehicle door having the window glass that slides in the lateral direction is established.

Although the above-described embodiment is applied to a side door attached to the side of the right front seat of a vehicle, application to other doors is also possible.

Moreover, although each embodiment of the present invention has been described, another embodiment of the present invention may be a combination of the above-described embodiments and modifications in whole or in part.

Moreover, the embodiments of the present invention are not limited to the above-described embodiments and modifications, and various changes, substitutions, and modifications may be made without departing from the spirit of the technical idea of the present invention. Furthermore, if the technical idea of the present invention can be realized in another way by advances in technology or another derived technology, the method may be used for implementation. Therefore, the claims cover all embodiments that can be included within the scope of the technical concept of the present invention.
