Description

  The present invention relates to a glass run attached to a sash provided in a vehicle body or door.

  As shown in FIGS. 6A and 6B, the glass run 61 includes a base portion 62 and a main body portion 65 including a pair of side wall portions 63 and 64 extending from the base portion 62, and the both side wall portions 63 and 64. And a pair of seal lips 66 and 67 extending from the substantially distal end to the inside of the main body 65. The main body 65 is attached to a sash S provided on the main body or door of the vehicle, and the inside and outside of the door glass G are sealed by the pair of seal lips 66 and 67.

  In general, the glass run 61 is divided into an extrusion-molded portion and a mold-molded portion in the longitudinal direction. The extrusion molding part is formed substantially linearly (in a long shape) by an extruder (not shown). The mold forming portion mainly corresponds to the corner portion, and is formed with a predetermined mold so that the two extruded portions are connected to each other at a predetermined angle (for example, 90 degrees).

  Conventionally, as shown in FIG. 6 (a), in both the extruded portion and the molded portion, a state where a pair of side wall portions 63 and 64 are expanded with respect to the base portion 62, that is, both side wall portions 63 and 64 are in the base. It is molded in a state where it is opened outward from the base portion with the portion 62 as a base point. This is due to the following reason. First, regarding the extrusion molding part, (1) in consideration of applying a predetermined lubricant to the inner peripheral surface of the base part 62 and the sliding surfaces of the glass of the seal lips 66 and 67, the molded part in an unfolded state. (2) If the seal lips 66 and 67 are close to each other, the seal lips 66 and 67 may be connected to each other immediately after molding, and this is to prevent it. On the other hand, with respect to the molded part, it is convenient to (1) make the shape follow the extruded part, and (2) to define the inner peripheral surfaces of the main body 65 and the seal lips 66 and 67 during the molding. It is necessary to set the core, but in the case of a mold having a cavity in which the seal lips 66 and 67 are close to each other, a thickness sufficient for a holding plate for holding the core unless it is molded in the expanded state. It is because it cannot be given.

  As shown in FIG. 6 (b), the glass run 61 molded in the unfolded state as described above is constricted from the unfolded state to the non-deployed state when the side walls 63 and 64 are attached to the sash S. . In other words, in the attached state, the side wall portions 63 and 64 are moved inward, and the main body portion 65 has a substantially U-shaped cross section. At this time, when the door glass G is not present, the tip portions of the seal lips 66 and 67 are in contact with each other.

  However, in the above technique, when the mold forming part is narrowed when attaching to the S to the sash, each part of the mold forming part (corner part) is not uniformly deformed, and the bending angle based on the stress at that time (Curvature radius, circumference, etc.) may change. In this case, the overall shape of the glass run 61 may not follow the sash shape, and attachment failure may occur.

  On the other hand, it is conceivable to design the glass run 61 in the unfolded state in anticipation of such a change in angle, etc., but in this case, it is impossible to predict what kind of angle change will occur. Trial and error must be repeated, resulting in a significant increase in design man-hours.

On the other hand, the base portion is formed into a bellows-like stretchable portion that can be stretched in and out of the vehicle, and the stretchable portion that has been stretched before being attached to the sash is shrunk when attached, There is also a glass run that fits into the sash (see, for example, Patent Document 1).
JP-A-9-315161

  However, as in the invention described in JP-A-9-315161 (conventional invention), a glass run of a type that has a bellows-like stretchable part and shrinks when attached to a sash, is stretched during shrinkage. Therefore, it may be difficult to maintain the shape of the glass run main body in an appropriate shape. For example, in the conventional invention, the base portion may be displaced in the thickness direction. As a result, problems such as poor mounting of the glass run and a decrease in sealing performance are caused.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a glass run capable of improving the shape retention of the door glass.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. Having an extrusion molded part formed by an extrusion molding method and a mold molding part formed by connection at the end of the extrusion molding part by a molding method;
A body portion attached to a vehicle body or a sash provided on a door, and having a substantially U-shaped cross section including a base portion and a vehicle inner side wall portion and a vehicle outer side wall portion extending from both ends of the base portion;
A pair of seal lips extending from the front end of the vehicle inner side wall and the vehicle outer side wall to the inside of the main body and sealing with the door glass,
A glass run formed on the base portion and having a stretchable portion that can be stretched in a vehicle interior and exterior direction,
Engaging protrusions are provided on both of the contact portions of the base body that are opposed to each other in the stretched state of the stretchable part and in contact in the contracted state of the stretchable part,
In the contracted state of the stretchable part, the two engaging protrusions are configured to engage at least in the thickness direction of the base part,
Both the base part main bodies are provided with projecting portions that protrude toward the base part main body opposite to the base part main body rather than the position of the connecting part between the base base body and the extendable part with respect to the vehicle interior / exterior direction. The glass run is characterized in that the projecting portions are brought into contact with each other before the stretchable portion is completely contracted.

  According to the means 1, even if the glass run is molded with the main body portion having a substantially U-shaped cross section in the non-deployed state, both the seal lips can be formed if the stretchable portion is molded in a state of extending in and out of the vehicle. A glass run having an open space can be obtained. As a result, even when a predetermined lubricant is applied, it can be easily applied to the inner peripheral surface of the base and the sliding surface of the glass of the seal lip, and both the seal lips are connected immediately after molding. The fear can be reduced. In addition, with respect to the molded part, the holding plate for holding the core of the mold can have a sufficient thickness. Furthermore, since it is not necessary to rotate and narrow the side wall portion in the mold forming portion from the unfolded state during the mounting operation, the angle, curvature radius, circumference, etc. of the mold forming portion do not change before and after the attachment. . Therefore, it is possible to avoid the problem that it is impossible to mount the sash along the shape of the sash. Further, in designing, it is not necessary to repeat trial and error in anticipation of the above change, so that the design man-hour can be reduced.

In addition, in the above-described means, the engagement protrusion is engaged at least in the thickness direction of the base portion, so that in the contracted state, the shape of the expansion / contraction portion and the body portion is maintained in an appropriate shape, and the door glass and glass The relative positional relationship with each part of the run can be properly maintained, and the shape retention of the glass run can be improved. As a result, during installation work, it is difficult to lose its shape, and the workability is dramatically improved. In addition, in the installed state, the sliding position and the contact position of the end face of the door glass are stabilized and the sealing performance is improved. Is planned. The same applies to the following means, but the term “engagement” here refers to a state of being engaged at least in the thickness direction of the base portion. However, in this means, since both the engaging protrusions engage with each other so that the movement of the base portion in both directions in the thickness direction of the base portion, that is, both the inside and outside directions of the main body portion is restricted, the above-described effect is more reliably achieved. Will be.
In addition, since both the contact parts are in a contact state before the expansion / contraction part is completely contracted, an extra load is applied to the expansion / contraction part, and the expansion / contraction part causes an inappropriate elastic deformation. Can be suppressed. As a result, the possibility that the locked state is released is reduced, and the above effect is enhanced.

  Mean 2. The glass run according to means 1, characterized in that a locking portion is provided on one of the engaging protrusions and a locked portion on which the locking portion is locked is provided on the other. .

  According to the means 2, the engagement protrusion is prevented from coming off by the locking. That is, the movement in the direction in which the vehicle inner side wall portion and the vehicle outer side wall portion are separated from each other is restricted. As a result, the effect of the means 1 is further enhanced.

[First Embodiment] (However, Reference Example)
First, a first embodiment will be described with reference to the drawings. In a vehicle having an elevator door glass, as shown in FIG. 1, a glass run 1 made of EPDM (ethylene-propylene-diene copolymer rubber) is attached corresponding to the outer peripheral shape of the door glass. More specifically, the door is provided with a sash S (see FIG. 2B) having a substantially U-shaped cross section in accordance with the outer peripheral shape of the door glass, and the glass of the present embodiment is provided on the sash S. Run 1 is attached.

  The glass run 1 includes an extrusion molding portion 2 corresponding to the upper side portion in the longitudinal direction, extrusion molding portions 3 and 4 corresponding to the front and rear vertical side portions, and ends of the extrusion molding portions 2, 3 and 4. It is comprised from the shaping | molding part 5 and 6 (part which attached | subjected the dot pattern in FIG. 1) to connect. Each extrusion molding part 2-4 is formed in the shape of a straight line (long shape) with the extrusion molding machine which is not illustrated. In addition, the molding parts 5 and 6 are connected and molded by a mold apparatus (not shown) so that the two extrusion molding parts 2 and 3 and the extrusion molding parts 2 and 4 are connected to each other at a predetermined angle. Is done. That is, the mold forming portions 5 and 6 correspond to the corner portions.

  As shown in FIGS. 2A and 2B, the extruded portions 2 to 4 and the molded portions 5 and 6 include a base portion 10 that is attached to the sash S and a vehicle inner side wall portion that extends from both ends of the base portion 10. 11 and a vehicle body side wall portion 12, and a main body portion 13 having a substantially U-shaped cross section. A pair of seal lips 14 and 15 for sealing is provided.

  The base portion 10 is formed with a stretchable portion 16 that can be stretched in the vehicle interior / exit direction. More specifically, the stretchable portion 16 is a section Z from the position intersecting with the extension line along the vehicle inner side surface of the door glass G in the base portion 10 to the position intersecting with the extension line along the vehicle outer side surface. The door glass G is provided at a position away from the facing portion of the end face of the door glass G. In the present embodiment, in the vehicle interior / exterior direction (left-right direction in FIG. 2 (a) and the like), it is provided on the vehicle inner side than the facing portion of the end surface of the door glass G and in the vicinity of the connecting portion with the vehicle interior side wall portion 11. It has been.

  The expansion / contraction part 16 is connected to the wall surfaces of both base part main bodies 10a and 10b opposite to each other with the expansion / contraction part 16 in between, and in an extended state, the expansion / contraction part 16 has a substantially reverse cross section that is convex toward the outside of the main body part 13. V-shaped. More specifically, the stretchable part 16 is thinner than the thickness Y of the base part 10. Both ends of the expansion / contraction part 16 are connected to the thickness direction of the base part 10 on the wall surfaces of the base part main bodies 10a and 10b [vertical direction in FIG. The portion is located inside the outer surface of the base portion 10. Therefore, the expansion / contraction part 16 is configured to fit within the thickness Y region of the base part 10 in both the expansion / contraction state and the contraction state, and does not protrude to both the inside and outside of the main body part 13.

  With the above-described configuration, the contact portions 10c and 10d of both base body bodies 10a and 10b that contact in the contracted state of the expansion / contraction part 16 are the doors of the base part 10 rather than the expansion / contraction part 16 in the thickness direction of the base part 10. It will be located in the opposing surface 10e side (inside of the main-body part 13) of the end surface of the glass G. FIG.

  Most of the abutting portions 10c and 10d are formed in a substantially planar shape substantially orthogonal to the facing surface 10e of the end surface of the door glass G of the base body 10a or 10b. An engagement protrusion 17 projecting outward is provided at the contact portion 10c of the base portion main body 10a inside the vehicle, and the engagement protrusion is provided at the contact portion 10d of the base portion main body 10b outside the vehicle. An engagement recess 18 into which 17 is inserted is provided. Further, a locking projection 17a as a locking portion is formed at the distal end of the engagement projection 17, and the locking projection 17a is locked at the back of the engagement recess 18. A locking recess 18a is formed as a stop. Of course, the engagement protrusion 17 may be provided at the contact portion 10d of the base portion main body 10b outside the vehicle, and the engagement recess 18 may be provided at the contact portion 10c of the base portion main body 10a inside the vehicle. Moreover, it is good also as a structure which replaced with the said structure and abbreviate | omitted the latching protrusion 17a and the latching recessed part 18a.

  As shown in FIG. 2 (a), the glass run 1 is molded in a state where the extruding parts 2-4 and the mold forming parts 5, 6 are extended in the vehicle interior / exit direction. Therefore, before the attachment to the sash S, the vehicle interior side wall portion 11 and the vehicle exterior side wall portion 12 have dimensions corresponding to the expansion of the expansion and contraction portion 16 while the main body portion 13 maintains a substantially U-shaped cross section in a non-deployed state. A predetermined opening amount W is ensured between the seal lips 14 and 15 in a state of being translated parallel to both sides.

  Further, when the glass run 1 is attached to the sash S, as shown in FIG. 2B, the telescopic portion 16 is contracted to move the vehicle inner side wall portion 11 and the vehicle outer side wall portion 12 in parallel. The abutting portions 10c and 10d of the base portion main bodies 10a and 10b are brought into contact with each other while the mating protrusion 17 is inserted into the engaging recess 18. As a result, the engagement protrusion 17 and the engagement recess 18 are engaged, and the movement of the base portion 10 in both directions in the thickness direction of the base portion 10, that is, in both the inside and outside directions of the main body portion 13, is regulated. Further, since the locking projection 17a is locked to the locking recess 18a and the engagement projection 17 is prevented from coming off from the engagement recess 18, the vehicle interior side wall portion 11 and the vehicle exterior side wall portion 12 are separated from each other. The movement in the direction to do is regulated. In this state, the entire area of the facing surface 10e of the end surface of the door glass G of the base portion 10 is substantially flush, and the stretchable portion 16 is not exposed to the facing surface 10e side of the end surface of the door glass G (inside the main body portion 13). It becomes a state. Then, the glass run 1 is fitted into the sash S while the main body 13 maintains a substantially U-shaped cross section in the non-deployed state. Therefore, when the glass run 1 is attached to the sash S, the stretchable portion 16 does not face the door glass G.

  As described above in detail, the glass run 1 is formed in a state in which the expansion / contraction part 16 is extended in the vehicle interior / exterior direction and the main body part 13 has a substantially U-shaped cross section in a non-deployed state. The body portion 13 is attached to the sash S in a state where the body portion 13 is contracted in the vehicle interior and exterior direction and has a substantially U-shaped cross section in a non-deployed state. Therefore, when the glass run 1 is formed, the gap between the seal lips 14 and 15 is opened, and a predetermined opening amount W is secured between the seal lips 14 and 15. As a result, even when a predetermined lubricant is applied, it can be easily applied to the inner peripheral surface of the base 10 and the glass sliding surfaces of the seal lips 14 and 15. The possibility that they will be connected can be reduced. Further, with respect to the mold forming portions 5 and 6, the holding plate for holding the core of the mold can have a sufficient thickness. Furthermore, since it is not necessary to rotate and narrow the side wall portions 11 and 12 in the mold forming portions 5 and 6 from the unfolded state at the time of mounting work, the angle, curvature radius, circumference, etc. of the mold forming portions 5 and 6 can be reduced. There is no change before and after installation. Therefore, it is possible to avoid a problem that the sash S cannot be attached along the shape of the sash S. Further, in designing, it is not necessary to repeat trial and error in anticipation of the above change, so that the design man-hour can be reduced.

  Further, an engagement protrusion 17 and an engagement recess 18 are provided, and the engagement protrusion 17 a and the engagement recess 18 a prevent the engagement protrusion 17 from coming off from the engagement recess 18. Thereby, in the contracted state, while maintaining the shape of the expansion / contraction part 16 and the main body part 13 in an appropriate shape, the relative positional relationship between the door glass G and each part of the glass run 1 can be appropriately maintained. This improves the shape retention. As a result, at the time of the mounting operation, the shape is not easily lost, and the workability is dramatically improved. In the mounting state, the possibility that the sliding door glass G abuts on the stretchable portion 16 is reduced, and the door glass is reduced. The sliding position and the contact position of the end face of G are stabilized, and the sealing performance is improved. Furthermore, the flushness of the facing surface 10e of the end surface of the door glass G of the base portion 10 is ensured.

[Second Embodiment]
Next, a second embodiment will be described with reference to the drawings. However, the detailed description of the same components as those in the first embodiment will be omitted, and only the stretchable part and the related parts will be described.

  As shown in FIGS. 3 (a) and 3 (b), the base portion 10 is formed with an expansion / contraction portion 21 that can expand and contract in the vehicle interior and exterior direction on the vehicle inner side than the facing portion of the end surface of the door glass G.

  Further, the wall surface of both base part main bodies 10a and 10b facing each other with the stretchable part 21 in between is directed toward the base part main body (base part main body 10a or base part main body 10b) facing each other. Protruding portions 22a and 22b that protrude along the opposing surface 10e of the end surface are provided. And the both ends of the expansion-contraction part 21 are connected with the base part vicinity of each protrusion site | part 22a, 22b. Accordingly, the projecting portions 22a and 22b project toward the base portion main bodies 10a and 10b facing each other than the position of the connecting portion between the base portion main bodies 10a and 10b and the telescopic portion 21 with respect to the vehicle interior / exterior direction. The front ends of 22a and 22b serve as contact portions when both base body 10a and 10b are in contact. With the above-described configuration, the contact portions of both base body bodies 10 a and 10 b in the contracted state of the stretchable part 21 are closer to the end surface of the door glass G of the base part 10 than the stretchable part 21 with respect to the thickness direction of the base part 10. It will be located in the opposing surface 10e side (inner side of the main-body part 13).

  Engagement protrusions 23 a and 23 b are provided at the distal ends of the protrusions 22 a and 22 b, respectively. When the telescopic part 21 is in the contracted state, the engagement protrusions 23 a and 23 b are in the thickness direction of the base part 10. It becomes a state of engagement.

Further, a locking protrusion 24a as a locking portion is formed on the outer surface of the main body 13 of the engaging protrusion 23a, and a locking protrusion 24a is formed on the inner surface of the main body 13 of the engaging protrusion 23b. A locking recess 24b is formed as a locked portion to be locked. Moreover, it is good also as a structure which replaced with the said structure and abbreviate | omitted the latching protrusion 24a and the latching recessed part 24b.

  The stretchable portion 21 has a substantially inverted V-shaped cross section that is convex toward the outside of the main body portion 13 in the extended state, and the thickness thereof is thinner than the thickness Y of the base portion 10. Further, the outer end portion of the main body 13 that is a bent portion is located on the inner side of the outer surface of the base portion 10. Therefore, the stretchable portion 21 is configured to be within the thickness Y region of the base portion 10 in both the stretched state and the contracted state, and does not protrude to both the inside and outside of the main body portion 13.

  When the glass run 1 is attached to the sash S, as shown in FIG. 3B, the telescopic portion 21 is contracted to move the vehicle inner side wall portion 11 and the vehicle outer side wall portion 12 in parallel. The engaging protrusions 23a and 23b are engaged. Thereby, the movement of the base portion 10 in both directions in the thickness direction of the base portion 10, that is, in both the inside and outside directions of the main body portion 13, is regulated. Furthermore, since the locking protrusion 24a is locked to the locking recess 24b, the movement in the direction in which the vehicle inner side wall portion 11 and the vehicle outer side wall portion 12 are separated is restricted. In this state, the entire area of the facing surface 10e of the end surface of the door glass G of the base portion 10 is substantially flush, and the stretchable portion 21 is not exposed to the facing surface 10e side (inside the main body portion 13) of the end surface of the door glass G. It becomes a state. Then, the glass run 1 is fitted into the sash S while the main body 13 maintains a substantially U-shaped cross section in the non-deployed state. Therefore, when the glass run 1 is attached to the sash S, the stretchable part 21 does not face the door glass G.

  Therefore, the same effect as the first embodiment is achieved. In addition, with the above configuration, since the tip portions (engagement projections 23a and 23b) of both the projecting portions 22a and 22b are in contact with each other before the expansion and contraction portion 21 is completely contracted, the extension portion 21 is extraneous. Can cause a problem that an excessive load is applied and the elastic part 21 causes an inappropriate elastic deformation. As a result, the shape of the stretchable part 21 and the main body part 13 in the contracted state is maintained in an appropriate shape.

[Third Embodiment] (However, Reference Example)
Next, a third embodiment will be described with reference to the drawings.

  As shown in FIGS. 4A and 4B, the glass run 1 includes a base portion 10 attached to the sash S, and a cross section composed of a vehicle inner side wall portion 11 and a vehicle outer side wall portion 12 substantially orthogonal to the base portion 10. A pair of seal lips 14, 15 that extend inward from the front end of the main body 13 having a substantially U-shape and the vehicle inner side wall 11 and the vehicle outer side wall 12 and seal the door glass G. And.

  In the present embodiment, at the time of molding, the vehicle interior side wall portion 11 and the base portion 10 are provided apart from each other, and the vehicle interior side wall portion 11 and the base portion 10 are connected to each other and an expandable / contractible portion 41 is provided. . And in the expansion | extension state of the expansion-contraction part 41, it is comprised so that the vehicle inner side wall part 11 and the base part 10 may space apart, and it may contact | abut in the contraction | contraction state of the expansion / contraction part 41, and the main-body part 13 can extend / contract at least inside and outside a vehicle. It is configured to be.

The base portion 10 includes a base portion main body 42 located on the vehicle outer side, and a projecting portion 43 that protrudes from the base portion main body 42 toward the vehicle inner side along the facing surface 10e of the end surface of the door glass G. . The thickness of the protruding portion 43 is thinner than the thickness Y of the base body 42. And the front-end | tip part of the protrusion part 43 becomes a contact part to the vehicle interior side wall part 11. FIG. Further, most of the front end portion of the projecting portion 43 has an end surface of the door glass G of the base portion 10 so that the front end portion comes into surface contact with the inner wall surface of the vehicle inner side wall portion 11 when contacting the vehicle inner side wall portion 11. Further, an engaging projection 44 projecting toward the vehicle interior side is provided at the tip of the projecting portion 43, and the contact portion of the vehicle interior side wall portion 11 is provided. Is provided with an engagement recess 45 into which the engagement protrusion 44 is inserted. Of course, it is good also as a structure by which the engagement protrusion 44 was provided in the contact part of the vehicle interior side wall part 11, and the engagement recessed part 45 was provided in the front-end | tip part of the protrusion part 43. FIG. In addition to the above configuration, a locking protrusion as a locking portion is formed at the tip of the engaging protrusion 44, and the locking protrusion is locked at the back of the engagement recess 44. It is good also as a structure in which the latching recessed part as a to-be-latched part to be formed was formed.

  Further, one end of the telescopic portion 41 is connected to a surface (surface outside the main body 13) opposite to the facing surface 10 e of the end surface of the door glass G in the protruding portion 43, and the other end is connected to the vehicle interior side wall 11. It is connected to. The connecting portion with the vehicle interior side wall portion 11 is located on the outer side of the main body portion 13 with respect to the thickness direction of the base portion main body 42 with respect to the abutting portion that is in contact with the distal end portion of the protruding portion 43. That is, in the contracted state of the stretchable portion 41, the base portion 10 abuts on the facing surface 10e side of the end surface of the door glass G rather than the stretchable portion 41, and the stretchable portion 41 is exposed to the facing surface 10e side of the end surface of the door glass G. No longer.

  When the glass run 1 is attached to the sash S, as shown in FIG. 4B, the telescopic portion 41 is contracted to move the vehicle inner side wall portion 11 and the vehicle outer side wall portion 12 in parallel. The base 10 is brought into contact with the vehicle interior side wall 11 while the mating protrusion 44 is inserted into the engagement recess 45. Thereby, the engagement protrusion 44 and the engagement recess 45 are engaged, and the movement of the base portion 10 in both directions in the thickness direction of the base portion 10, that is, in both the inside and outside directions of the main body portion 13 is restricted. In this state, the entire area of the facing surface 10e of the end surface of the door glass G of the base portion 10 is substantially flush, and the stretchable portion 41 is not exposed to the facing surface 10e side (inside the main body portion 13) of the end surface of the door glass G. It becomes a state. Then, the glass run 1 is fitted into the sash S while the main body 13 maintains a substantially U-shaped cross section in the non-deployed state. Therefore, when the glass run 1 is attached to the sash S, the stretchable portion 16 does not face the door glass G.

  Furthermore, in the contracted state, the expansion / contraction part 41 is in a state of being double-folded on the surface opposite to the facing surface 10e of the end surface of the door glass G in the protruding portion 43, and within the thickness Y region of the base portion main body 42. It is configured to fit in. Thereby, the expansion-contraction part 41 does not protrude to the outer side of the main-body part 13, and the glass run 1 can be attached to the sash S appropriately.

  Therefore, the same effect as the first embodiment is achieved. In addition, with the above-described configuration, it is possible to obtain a relatively large amount of extension in the vehicle interior / exit direction at the time of extension while suppressing the amount of protrusion of the expansion / contraction part 41 in the thickness direction of the base 10.

[Fourth Embodiment] (However, Reference Example)
Next, a fourth embodiment will be described with reference to the drawings.

  As shown in FIGS. 5A and 5B, the glass run 1 includes a base portion 10 attached to the sash S, and a cross section including a vehicle inner side wall portion 11 and a vehicle outer side wall portion 12 substantially orthogonal to the base portion 10. A pair of seal lips 14, 15 that extend inward from the front end of the main body 13 having a substantially U-shape and the vehicle inner side wall 11 and the vehicle outer side wall 12 and seal the door glass G. And.

  In the present embodiment, at the time of molding, the vehicle interior side wall portion 11 and the base portion 10 are provided apart from each other, and the vehicle interior side wall portion 11 and the base portion 10 are connected to each other and an expandable / contractible portion 51 is provided. . And in the expansion | extension state of the expansion-contraction part 51, it is comprised so that the vehicle inner side wall part 11 and the base part 10 may space apart, and it may contact | abut in the contraction | contraction state of the expansion / contraction part 51, and the main-body part 13 can extend / contract at least inside and outside a vehicle It is configured to be.

  The stretchable portion 51 is thinner than the thickness of the base portion 10, one end thereof is connected to the facing surface 10 e of the end surface of the door glass G of the base portion 10, and the other end is the vehicle interior side wall portion 11. It is connected to the inner wall surface. Therefore, the expansion / contraction part 51 is the door glass which is the zone Z from the position which cross | intersects the extension line along the vehicle inner side surface of the door glass G in the base part 10 to the position which cross | intersects the extension line along the vehicle outer side surface. It is provided at a position deviating from the facing portion of the end face of G. In this embodiment, it is provided on the vehicle inner side with respect to the vehicle interior / exterior direction (the left-right direction in FIG. 5A and the like) rather than the facing portion of the end face of the door glass G.

  Further, the vehicle inner side end portion of the base portion 10 is substantially orthogonal to the facing surface 10e of the end surface of the door glass G of the base portion 10 so as to come into surface contact with the vehicle inner side wall portion 11 when contacting the vehicle inner side wall portion 11. It is substantially planar.

  Further, an engagement protrusion 53 protruding toward the vehicle inner side is provided at the vehicle inner end portion of the base portion 10, and the engagement protrusion 53 is inserted into a contact portion of the vehicle inner side wall portion 11. A mating recess 54 is provided. Of course, it is good also as a structure by which the engagement protrusion 53 was provided in the contact part of the vehicle inner side wall part 11, and the engagement recessed part 54 was provided in the vehicle inner side edge part. In addition to the above configuration, a locking protrusion as a locking portion is formed at the tip of the engaging protrusion 53, and the locking protrusion is locked at the back of the engagement recess 54. It is good also as a structure in which the latching recessed part as a to-be-latched part to be formed was formed.

  When the glass run 1 is attached to the sash S, as shown in FIG. 5B, the telescopic portion 41 is contracted to translate the vehicle inner side wall portion 11 and the vehicle outer side wall portion 12 in parallel. The vehicle inner side end portion of the base portion 10 is brought into contact with the vehicle inner side wall portion 11 while the mating protrusion 53 is inserted into the engagement concave portion 54. Thereby, the engagement protrusion 53 and the engagement recess 54 are engaged, and the movement of the base portion 10 in both directions in the thickness direction of the base portion 10, that is, in both the inside and outside directions of the main body portion 13, is restricted. Then, the glass run 1 is fitted into the sash S while the main body 13 maintains a substantially U-shaped cross section in the non-deployed state.

  Therefore, the same effect as the first embodiment is achieved. In addition, since it becomes a structure which is not exposed to the outer side of the main-body part 13 by the said structure, the glass run 1 can be attached to the sash S appropriately. Furthermore, the possibility that the end surface of the door glass G abuts on the stretchable part 51 is reduced.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) In the above embodiment, the glass run 1 is attached to the sash S provided on the side door, but may be embodied to the glass run 1 attached to the vehicle main body side.

  (B) The shape and configuration (direction, etc.) of the contraction portion 16 and the like in each embodiment are not limited to the above-described embodiment. For example, a bellows-shaped stretchable part may be employed.

  (C) The arrangement position of the expansion / contraction part 16 etc. with respect to the vehicle interior / exterior direction is not limited to the vehicle interior side rather than the facing portion of the end surface of the door glass G, and may be, for example, the vehicle exterior side. You may arrange | position according to the opposing site | part.

( D ) In the above embodiment, the explanation has been given mainly using the extrusion molding part 2 (cross-sectional view shown in FIG. 2 and the like) as an example, but of course, at least one of the extrusion molding parts 2 to 4 and the molding parts 5 and 6; In particular, only the mold forming portions 5 and 6 may be positioned by the engaging protrusions 17 and the engaging recesses 18 (configurations that are engaged and locked). Moreover, when the engagement protrusions 17 etc. are provided in both the extrusion-molding parts 2-4 and the shaping | molding parts 5 and 6, it is good also as a structure by which both engagement protrusions 17 etc. are formed continuously, separately. It is good also as a structure formed. As a structure formed separately, for example, in the extrusion molding parts 2 to 4, the engagement protrusions are continuously formed as protrusions, and in the mold forming parts 5 and 6, at least one protrusion is formed as the engagement protrusions. A configuration is given as an example.

( E ) In the above embodiment, the glass run 1 is made of EPDM, but may be made of other materials such as olefin-based thermoplastic elastomer (TPO) or soft polyvinyl chloride.
