  Here, when the grommet of Patent Document 1 is used to route the door wire harness across the waterproof weather strip disposed along the side surface of the door, the weather strip is used as the grommet. Located across the surface of the body. Specifically, the weather strip is fixed and adhered to the side surface portion of the door with a clip in each of the upper and lower sides of the grommet body in a state of being in close contact with the surface of the side surface portion of the door. And a weather strip passes the surface of a grommet main body in the up-down direction in the attachment position of a grommet main body. When the door is closed, the weather strip is sandwiched between the vehicle and the body, and the weather strip is pressed against the grommet body and the vehicle body to prevent water from entering the door from the surface of the grommet body. Figured.

  In the grommet as described above, the peripheral portion of the grommet body is in pressure contact with the side surface portion of the door, and the peripheral portion of the grommet main body slightly protrudes from the side surface portion of the door. For this reason, the weather strip that crosses the surface of the grommet body is difficult to adhere to the side surface of the door at the outer periphery of the periphery of the grommet body, and the triangle is between the periphery of the grommet body, the side surface of the door, and the weather strip. There is a risk of forming a gap in the shape. Thereby, even if the door is in a closed state, there is a possibility that water may enter from the outdoor side to the indoor side through the gap.

  Therefore, an object of the present invention is to more reliably suppress the ingress of water that passes between the side portion of the door and the weather strip on the outer peripheral side of the grommet body.

In order to solve the above-mentioned problem, the first and second aspects are for doors for disposing a wire harness via a recess formed so as to reach from the side of a vehicle door to the inside of the door. A grommet, which closes the opening on the side surface side of the recess, and has a base portion formed with an outer peripheral seal portion capable of abutting on the outer peripheral side portion of the concave portion of the side surface on the peripheral portion And a grommet body that is formed on the surface of the base portion and includes a protective cylinder portion that covers the wire harness, and a weather strip attached to the surface of the side portion is disposed across the surface of the base portion. And a projecting seal portion that can contact the surface of the side portion protrudes from a side position of the outer peripheral portion of the base portion where the weather strip passes.

The first aspect is formed by rigid material than prior Symbol grommet main body, further comprising a rigid member which is disposed within the grommet body, said rigid member, the said projecting seal portion side It includes a protruding pressing part that presses against the surface.

The second aspect is, prior Symbol protruding sealing portion includes a protruding seal portion formed in width smaller than its overall width.

It protrudes in the direction.

The wire harness with a grommet which concerns on a 4th aspect is provided with the grommet for doors which concerns on any one 1st- 3rd aspect, and the wire harness arrange | positioned through the said protection cylinder part.

According to the 1st-4th aspect, the protrusion seal part which can contact | abut on the said side part surface is protrudingly provided in the side position of the position where the said weather strip passes among the outer peripheral parts of the said base part. For this reason, even if a gap is generated between the side portion of the door and the weather strip on the outer peripheral side of the grommet body, the gap is covered with the protruding seal portion. As a result, it is possible to more reliably suppress the entry of water through the gap.

According to the first aspect, the protruding seal portion that is a part of the rigid member can more reliably press the protruding seal portion toward the side surface, thereby preventing water from entering through the gap. It can suppress more reliably.

According to the second aspect, since the projecting seal portion can be pressed against the side surface by deforming the relatively thin ridge seal portion, the space between the projecting seal portion and the side surface is more reliably sealed. Can do. Thereby, the said clearance gap can be covered more reliably by the protrusion seal | sticker part, and the penetration | invasion of the water through the said clearance gap can be suppressed more reliably.

  More specifically, a grommet mounting recess 16 for mounting the grommet 30 is formed in a portion of the door 10 that faces the hinge portion. The grommet mounting recess 16 is formed in a concave shape that extends from the side of the door 10 to the vehicle interior side. The grommet mounting recess 16 includes a side recess 17 that is recessed at the vehicle interior side of the side plate 14 of the door inner panel 12, and a vehicle interior recess 18 that is recessed at the side plate 14 side of the vehicle interior panel 15 of the door inner panel 12. including. The side recess 17 and the vehicle interior recess 18 are L-shaped in plan view, and the door grommet 30 is mounted in the grommet mounting recess 16 including these.

  In addition, the bottom of the side recess 17 is a first bottom 17a that is recessed from the periphery at the middle in the vertical direction inside the vehicle, and a second bottom that is shallower on the top and bottom and outside the vehicle relative to the first bottom 17a. 17b. Two bolt insertion holes 17bh are formed at positions outside the first bottom portion 17a of the second bottom portion 17b. Here, the two bolt insertion holes 17bh are formed side by side in the vertical direction. The positions where the two bolt insertion holes 17bh are formed correspond to two bolt insertion holes 44 and 45 on the door grommet 30 side which will be described later. Further, a nut N (see FIG. 9) is disposed inside the two bolt insertion holes 17bh. Then, the shaft portion Bb of the bolt B inserted into the main bolt insertion hole 17bh is screwed and fastened to the main nut N. The nut N may be fixed to the inner surface of the side plate 14, or may be disposed on the inner surface of the side plate 14 and screwed with the bolt B when the bolt B is inserted.

  The wire harness WH is guided from the indoor side of the door 10 toward the grommet mounting recess 16 and is guided into the door grommet 30 in the grommet mounting recess 16. More specifically, the door harness grommet 30 is mounted on the grommet mounting recess 16 and the wire harness WH is bent in an L shape and is disposed via the grommet mounting recess 16. The wire harness WH is guided through the door grommet 30 toward the hinge-side side plate T in the door opening of the body.

  A weather strip 19 is attached to the side plate 14 of the door 10 to partition the outside of the vehicle interior. The weather strip 19 is a long member formed of an elastic member such as rubber. The weather strip 19 passes through the door grommet 30 mounted in the grommet mounting recess 16 and extends in the extending direction (here, the side plate 14). (Vertical direction). The weather strip 19 is attached and fixed to the side plate 14 by, for example, a structure in which a resin component is attached to the surface of the weather strip 19 that contacts the side plate 14 and the resin component is fitted into the hole of the side plate 14 and locked. Is done. The weather strip 19 contacts the side plate T on the body side when the door 10 is closed.

FIG. 8 is an end view of the section cut along the line VII-VII in FIG. 5, and FIG. 8 is an end view of the section cut along the line VIII-VIII in FIG. 9 is a schematic plan view showing a state in which the wire harness 20 with grommet is mounted in the grommet mounting recess 16, and FIG. 10 is a front view of the door grommet 30 (a cross-sectional view taken along line XX in FIG. 9). 11 is an enlarged view of an arrow Q portion in FIG. 10, and FIG. 12 is an enlarged view of an arrow P portion in FIG. 13 and 14 are perspective views showing the mounting member 40. FIG.

  The wire harness with grommet 20 includes a door grommet 30 and a wire harness WH routed through the door grommet 30.

  The wire harness WH is a wiring member that connects the electrical component on the body side and the electrical component on the door side, and includes at least one electric wire. Usually, the wire harness WH includes a plurality of electric wires, and a connector or the like is connected to the end thereof. And this wire harness WH is electrically connected to the electrical component of the body side or the door side via the said connector. The wire harness WH may include an optical cable.

  The door grommet 30 includes an attachment member 40 as a rigid member, a grommet body 60, and a protector 32.

  The attachment member 40 is made of a material having higher rigidity than the grommet body 60, for example, metal or resin. Here, the attachment member 40 is formed of a metal plate having higher rigidity. By attaching the mounting member 40 to the grommet mounting recess 16 via the bolt B and the nut N, the door grommet 30 is held in a state of being fixed to the grommet mounting recess 16.

  Note that the attachment member may be attached to the grommet attachment recess by another attachment configuration. For example, the mounting member may be formed with a lock part that can be fitted and fixed in a hole formed in the grommet mounting recess, and the door grommet may be fixed to the mounting member via the lock part. Further, the mounting member 40 may be omitted, and the grommet body may be directly mounted and fixed in the grommet mounting recess.

  The grommet main body 60 is made of a material richer in elasticity than the mounting member 40, such as rubber. The grommet main body 60 serves to seal the gap between the attachment member 40 and the side plate 14 and to cover and protect the wire harness WH between the door 10 and the body.

  The protector 32 is a member formed of resin or the like, and is attached to the inner surface side of the attachment member 40. The protector 32 plays a role of holding the wire harness WH in a fixed position between the attachment member 40 and the protector 32 and protecting the wire harness WH. The protector 32 may be omitted.

  Each of the above components will be described more specifically.

  The attachment member 40 is a member formed by pressing a metal plate or the like, and includes an attachment main body portion 42 and a vehicle interior closing portion 50 (see particularly FIGS. 13 and 14).

  The mounting main body 42 is a portion of the grommet mounting recess 16 that covers the side opening of the door 10, that is, a portion of the side recess 17 that covers the opening on the side plate 14 side. It is a part which covers the vehicle inside opening of the recessed part 16, ie, the vehicle inside opening of the vehicle inside recessed part 18. The attachment main body 42 and the vehicle interior closing portion 50 are connected so as to form an L shape.

  More specifically, the attachment main body 42 as a rigid member is formed in a rectangular plate shape that covers the opening on the side plate 14 side of the side recess 17. Two corners on the front end side of the mounting main body 42 are rounded so as to form an arc shape.

  The attachment main body portion 42 is formed with a wire harness lead hole 43 through which the wire harness WH can be drawn. Here, a rectangular wire harness lead-out hole 43 is formed at a position in the middle in the longitudinal direction of the mounting main body 42 and in the middle in the width direction (vertical direction). An encircling wall portion 43 w that protrudes outward from the side plate 14 of the door inner panel 12 is formed at the peripheral edge portion of the wire harness lead-out hole 43.

  In addition, a protector fixing piece 43 a that protrudes toward the inside of the wire harness extraction hole 43 is formed to protrude in an intermediate portion in the extending direction of the side portion on the distal end side of the attachment main body portion 42 in the wire harness extraction hole 43. .

  Further, the mounting main body 42 is formed with a first bolt insertion hole 44 and a second bolt insertion hole 45 that are continuously arranged. Here, the first bolt insertion hole 44 and the second bolt insertion hole 45 are formed side by side. The side where the first bolt insertion hole 44 and the second bolt insertion hole 45 are bolted and fixed. On the other side (the side facing the outer side when mounted on the side plate 14) side, without interposing other parts such as a harness protection cylinder part 70, which will be described later, between them. Say. As a result, as will be described in detail later, the space between the first bolt insertion hole 44 and the second bolt insertion hole 45 is bolted to fix the bolt B inserted through the first bolt insertion hole 44. The space and the bolt B inserted through the second bolt insertion hole 45 can be shared as a work space for bolting and fixing.

  Further, since the first bolt insertion hole 44 and the second bolt insertion hole 45 are formed, the door grommet 30 can be fixed to the grommet mounting recess 16 using the two bolts B. Thereby, rotation suppression of the grommet 30 for doors is achieved.

  In addition, the first bolt insertion hole 44 and the second bolt insertion hole 45 are a part of the attachment main body 42 opposite to the vehicle interior blocking part 50 across the wire harness lead-out hole 43, that is, the attachment main body 42. It is formed in the front-end | tip part. Thereby, the volt | bolt B can be penetrated avoiding the arrangement | positioning path | route of the wire harness WH. Moreover, the front-end | tip part of the attachment main-body part 42 will be fixed with respect to the grommet mounting recessed part 16, and the fixing force is made to act on the upper part and lower part of the attachment main-body part 42 as much as possible. Can do.

  The first bolt insertion hole 44 and the second bolt insertion hole 45 are formed so as to be lined up and down. The distance between the upper first bolt insertion hole 44 and the upper edge of the attachment main body 42 is the same as the distance between the lower second bolt insertion hole 45 and the lower edge of the attachment main body 42. In other words, the first bolt insertion hole 44 and the second bolt insertion hole 45 are formed at symmetrical positions across the center line in the width direction (vertical direction) of the attachment main body 42.

  Also from this point, the tightening force of the bolt B inserted through the first bolt insertion hole 44 and the second bolt insertion hole 45 acts as a substantially similar force on the upper portion and the lower portion of the mounting main body portion 42. It will be.

  When the door grommet 30 is attached to the left door of the vehicle, the upper part is arranged on the lower side when attached to the right door, and the lower side is attached to the right side door. The portion disposed on the upper side is disposed on the upper side. Therefore, as described above, the door grommet 30 is provided on both the left and right doors of the vehicle by adopting a configuration capable of exerting substantially the same tightening force on the upper portion and the lower portion of the mounting main body 42. It can be set as the structure suitable for the attachment to.

  Moreover, since the first bolt insertion hole 44 and the second bolt insertion hole 45 are formed so as to be lined up and down, the first bolt insertion hole 44 and the second bolt insertion hole 45 are attached from the wire harness lead-out hole 43 as compared with the case where they are formed so as to be aligned in the horizontal direction. The length dimension up to the tip of the main body 42 can be made as small as possible. Thereby, the length dimension of the attachment main-body part 42 can be made as small as possible, and can be easily accommodated in the thickness dimension (width | variety of the side plate 14) of the door 10. FIG.

  In addition, cylindrical portions 44 a and 45 a that protrude toward the grommet mounting recess 16 are formed at the peripheral portions of the first bolt insertion hole 44 and the second bolt insertion hole 45. Accordingly, the first bolt insertion hole 44 and the second bolt insertion hole 45 are reinforced.

  The mounting main body 42 is formed with reinforcing protrusions 46a, 46b, and 46c.

  The reinforcing protrusion 46a is formed by folding the edge on the tip side of the mounting main body 42 and the tip side portions of both edges in the width direction (vertical direction) of the mounting main body 42 so as to face the outside of the side plate 14. It is formed by bending. The reinforcing protrusion 46a reinforces the attachment main body 42 so as not to bend in a direction perpendicular to the surface. In particular, a portion extending along the extending direction of the mounting main body portion 42 of the reinforcing protrusion 46a (a portion formed at the front end side portion of the edge on both sides in the width direction (vertical direction) of the mounting main body portion 42). The mounting main body portion 42 does not easily bend between the first bolt insertion hole 44 and the second bolt insertion hole 45 from both side portions toward the both side portions of the wire harness lead-out hole 43. Reinforce to. Thereby, the tightening force of the front end portion of the attachment main body portion 42 by the bolt B effectively reaches the intermediate portion in the extending direction of the attachment main body portion 42.

  The reinforcing protrusion 46b is formed at a position from the inside of the portion excluding the low-rigidity connecting portion 58 (described later) on the both sides in the width direction (vertical direction) of the mounting main body 42. ing. The reinforcing protrusion 46b is formed by the low-rigidity connecting portion 58 on the proximal end side of the mounting main body portion 42 from the side portions of the first bolt insertion hole 44 and the second bolt insertion hole 45, which are the distal end portions of the mounting main body portion 42. It is formed so as to extend toward the front. In addition, the reinforcing protrusion 46b is formed in an elongated shape on one surface side (the grommet mounting recess 16 side) of the mounting main body portion 42, and is elongated in the other surface side (the outer surface side of the side plate 14) of the mounting main body portion 42. It is formed by.

  Due to the reinforcing protrusion 46b, the intermediate portion of the mounting body 42 is bent with respect to the portion of the tip of the mounting body 42 where the first bolt insertion hole 44 and the second bolt insertion hole 45 are formed. Reinforced so that there is no. As a result, the tightening force of the front end portion of the attachment main body portion 42 by the bolt B effectively reaches the intermediate portion in the extending direction of the attachment main body portion 42.

  The reinforcing protrusion 46 c is formed in the width direction (vertical direction intermediate portion) of the portion of the attachment main body 42 between the wire harness lead hole 43 and the low-rigidity connecting portion 58. Here, the reinforcing protrusions 46 c are formed in an elongated shape extending along the extending direction of the attachment main body 42, and a plurality (here, five) are formed in the width direction of the attachment main body 42. . Each reinforcing protrusion 46c is formed by recessing one surface side (grommet mounting recess 16 side) of the mounting main body 42 in an elongated manner, and the other surface side (side plate 14 of the side plate 14). It is formed by elongating and projecting to the outer surface side).

  The reinforcing protrusion 46c reinforces the portion of the mounting main body 42 between the wire harness lead hole 43 and the low-rigidity connecting portion 58 so that the portion does not bend. The state of closing the part is more reliably maintained.

  Part or all of the reinforcing protrusions 46a, 46b, and 46c may be omitted.

  Further, the mounting main body portion 42 is formed with holes 47 penetrating on both sides thereof. Here, the plurality of holes 47 are provided on the front end side of the mounting main body 42 with respect to the first bolt insertion hole 44 and the second bolt insertion hole 45, the first bolt insertion hole 44, the second bolt insertion hole 45, and the wire. It is formed in a portion between the harness lead-out hole 43 and a portion between the wire harness lead-out hole 43 and the low-rigidity connecting portion 58 and avoiding the reinforcing protrusion 46c. And the inside of the grommet main body 60 formed by injection mold using the mounting main body portion 42 as an insert enters the main hole 47. Thereby, the position shift of the grommet main body 60 with respect to the attachment main-body part 42 is suppressed.

  In addition, a portion of the attachment main body 42 on the vehicle inner side closing portion 50 side is formed in a low-rigidity connecting portion 58 having a lower rigidity than other portions. Here, a weakening hole 58 h is formed in the width direction (vertical direction) of the low-rigidity connecting portion 58. Here, a plurality (three in this case) of weakening holes 58h are formed along the width direction (vertical direction) of the low-rigidity connecting portion 58. The weakening hole 58 h is formed in a long hole shape along the extending direction of the attachment main body 42. By the weakening hole 58h, the low-rigidity connecting portion 58 is formed with a lower rigidity than the other portions of the attachment main body portion 42, and can be easily bent and deformed. In particular, since the weakening hole 58h is formed in a long hole shape along the extending direction of the attachment main body portion 42, the low-rigidity connecting portion 58 extends over a certain long region in the extending direction of the attachment main body portion 42. It can be formed and the deformation area can be enlarged. Here, the low-rigidity connecting portion 58 is formed to be narrower than the other portions of the attachment main body portion 42, so that the low-rigidity connecting portion 58 is also made smaller than the other portions of the attachment main body portion 42. It is formed with low rigidity.

  Even when a force in a direction perpendicular to the surface acts on the low-rigidity connecting portion 58 at the base end portion of the mounting main body 42, the force is mainly generated by bending the low-rigidity connecting portion 58. As a result, the portion of the mounting main body 42 other than the low-rigidity connecting portion 58 does not easily float from the grommet mounting recess 16.

  In addition, projecting pressing portions 49 projecting outward are formed at intermediate portions in the extending direction of both side portions (upper portion and lower portion) of the mounting main body portion 42. The projecting and pressing portion 49 is formed at a position from the side where the weather strip 19 passes when the door grommet 30 is attached to the grommet mounting recess 16 and the weather strip 19 is attached to the side plate 14 of the door 10. Specifically, it is the side of the vehicle outer side where the weather strip 19 passes. Here, the weather strip 19 is disposed through a portion of the surface of the grommet main body 60 that is closer to the vehicle interior than the wire harness lead-out hole 43. For this reason, the projecting and pressing portions 49 are formed on both sides of the mounting main body portion 42 at positions on the upper and lower sides of the base end side portion of the mounting main body portion 42 in the peripheral portion of the wire harness lead-out hole 43. Has been.

  Further, the projecting and pressing portion 49 is extended to the outer surface side of the side plate 14 from both sides of the mounting main body portion 42 to the outside, and is extended to the distal end portion of the inclined portion 49a. (That is, an outer surface of the side plate 14) and a pressing portion 49b extending along the same direction. The pressing portion 49b is formed in a rectangular plate shape with two corners on the tip side rounded. Then, with the door grommet 30 attached to the grommet mounting recess 16, the inclined portion 49 a is disposed along the outer peripheral inclined surface of the grommet mounting recess 16, and the pressing portion 49 b is attached to the grommet mounting surface of the side plate 14. It is disposed along the outer peripheral portion of the recess 16. And the protrusion seal part 65 which covers this protrusion pressing part 49 among the grommet main bodies 60 with the press part 49b is a part around the grommet mounting recessed part 16 among the surfaces of the side plate 14, and is adjacent to the weather strip 19. Pressed. Further, the extended protrusion seal portion 64 d described later of the grommet body 60 is pressed against the inclined surface around the grommet mounting recess 16 by the inclined portion 49 a.

  In front view, the protruding pressing portion 49 is inclined (slightly inclined here) so as to be directed outward and toward the distal end side (vehicle outer side) of the mounting main body portion 42.

  The vehicle interior closing portion 50 is formed in a rectangular plate shape that covers the vehicle interior opening of the vehicle interior recess 18, and is curved in an arc shape with respect to the low-rigidity connection portion 58 that is the base end portion of the attachment main body portion 42. It is connected via a bent portion 57. The vehicle interior closing portion 50 extends in a right angle posture with respect to the attachment main body portion 42.

  The vehicle inner side blocking portion 50 is set to have the same width as the low-rigidity connecting portion 58, and the tip portion thereof is bent so as to protrude toward the vehicle inner side. Further, protector fixing convex portions 52 are provided on both side portions of the front end portion of the vehicle inner side blocking portion 50. Further, the base end portion of the vehicle inner side blocking portion 50 is formed in a portion 51 having a lower rigidity than the other portions. Here, a plurality (four in this case) of holes 51h are formed in the base end portion of the vehicle inner side blocking portion 50 along the width direction thereof. Here, each hole 51h is formed in a round hole. When a force in a direction perpendicular to the surface of the vehicle inner side blocking portion 50 (that is, a direction toward the outside of the vehicle interior) is applied, the vehicle inner side blocking portion 50 is mainly formed by the low-rigidity portion 51. Deform. Accordingly, the force is unlikely to act on the attachment main body 42.

  The grommet body 60 is a member integrally formed of an elastic member such as rubber, and includes a base portion 62, a harness protection cylinder portion 70, and a body side mounting portion 80 (see FIGS. 3 and 4).

  The base portion 62 has a configuration in which a flat-shaped portion that covers the mounting main body portion 42 of the mounting member 40 and a flat-shaped portion that covers the base end portion of the vehicle inner side blocking portion 50 are continuously provided in an L shape. .

  The base portion 62 is formed in a shape corresponding to the opening on the surface side of the side plate 14 of the grommet mounting recess 16, that is, the opening corresponding to the opening of the side recess 17, so that the opening can be blocked. ing. A space that can accommodate the mounting main body 42 and the base end portion of the vehicle inner side blocking portion 50 is formed in the base portion 62, and the base of the mounting main body portion 42 and the vehicle inner side blocking portion 50 is formed in this space. The base portion 62 is attached to the attachment member 40 by accommodating the end portion. Preferably, the base part 62 is mounted on the mounting member 40 by molding the grommet body 60 by injection molding using the mounting member 40 as an insert. Of course, the grommet body 60 may be molded separately from the mounting member 40, and after the grommet body 60 is molded, the mounting member 40 may be fitted into the grommet body 60.

  Outer peripheral edge seal portions 63 are formed at positions corresponding to both side edge portions and front end side edge portions of the mounting body portion 42 in the width direction (vertical direction) of the base portion 62. The outer peripheral seal portion 63 is formed thinner than the base end side portion of the outer peripheral seal portion 63 in the base portion 62 and is formed in a shape facing the grommet mounting recess 16 toward the distal end side (see FIG. 6). Preferably, the distal end portion of the outer peripheral seal portion 63 is formed in a shape that gradually becomes thinner toward the distal end side. Then, in a state where the door grommet 30 is mounted in the grommet mounting recess 16, the outer peripheral seal portion 63 comes into close contact with the outer peripheral side portion of the grommet mounting recess 16 in the side plate 14, and the side plate 14 and the door grommet Waterproof between 30.

  In addition, internal seal portions 64 a, 64 b, 64 c are formed in a portion of the base portion 62 that faces the grommet mounting recess 16.

  The inner seal portions 64a, 64b, 64c are formed in an elongated ridge shape.

  The inner seal portion 64a is formed as a bolt insertion hole seal portion in an annular shape surrounding the first bolt insertion hole 44 and the second bolt insertion hole 45, more specifically, a rectangular annular shape. The internal seal portion 64b is formed so as to extend from both ends in the extending direction of the internal seal portion 64a along both sides in the width direction (vertical direction) of the mounting main body portion 42. The internal seal portion 64 c is formed so as to extend from the end portion of the internal seal portion 64 b toward the outer peripheral edge portion of the base portion 62.

  The inner seal portions 64 a and 64 b are in contact with the second bottom portion 17 b of the grommet mounting recess 16 while the door grommet 30 is mounted in the grommet mounting recess 16. Thereby, the space | gap of the grommet 30 for doors and the grommet mounting recessed part 16 is sealed by the internal seal parts 64a and 64b also between the outer periphery seal part 63 and the arrangement | positioning area | region of the wire harness WH, and more reliable waterproofing is carried out. Figured. Further, in this state, the inner seal portion 64 c comes into contact with the inward circumferential surface surrounding the second bottom portion 17 b of the grommet mounting recess 16. By this internal seal portion 64c, the space between the door grommet 30 and the grommet mounting recess 16 and between the outer peripheral seal portion 63 and the area where the wire harness WH is disposed is sealed between the vehicle interior and the exterior.

  The inner seal portion 64a is pressed against the second bottom portion 17b of the grommet mounting recess 16 in a state of surrounding the first bolt insertion hole 44 and the second bolt insertion hole 45 as a bolt insertion hole seal portion. Thereby, it can suppress more reliably that water permeates between the grommet main body 60 and the grommet mounting recess 16 around the first bolt insertion hole 44 and the second bolt insertion hole 45.

  A protruding seal portion 65 that covers the protruding and pressing portion 49 is formed at a position corresponding to the protruding and pressing portion 49 in the base portion 62. That is, the protruding seal portions 65 are formed on both upper and lower side portions of the base portion 62.

  Here, the protruding seal portion 65 covers the entire outer periphery of the pressing portion 49 b on the distal end side of the protruding pressing portion 49. The projecting seal portion 65 projects along the extending direction of the projecting pressing portion 49. Therefore, in the front view, the projecting seal portion 65 faces the distal end side (the vehicle outer side) of the mounting main body portion 42 toward the outside. Inclined to face (slightly inclined here).

  Note that the protruding seal portion may cover only a portion of the pressing portion that faces the side plate.

  On the surface of the protruding seal portion 65 facing the side plate 14, a ridge seal portion 65 a is formed along the peripheral edge portion. That is, a U-shaped ridge seal portion 65 a is formed along the leading edge and both side edges of the protruding seal portion 65. The ridge seal portion 65a is smaller than the width of the protruding seal portion 65, and therefore can be easily elastically deformed by pressing the ridge seal portion 65a against the side plate 14.

  A pair of extended ridge seal portions 64d are formed from the two base end portions of the ridge seal portion 65a toward the internal seal portion 64b. 49a is embedded in the portion of the base portion 62 where the pair of extended ridge seal portions 64d is formed. Accordingly, the pair of extended ridge seal portions 64d is provided with the grommet mounting recesses by the inclined portions 49a. 16 is pressed against the inclined surface on the outer peripheral side. The pair of extended ridge seal portions 64d also seals the gap between the grommet body 60 and the grommet mounting recess 16 outside the vehicle interior.

  Further, a pair of elongated protrusions 67 that reach the intermediate portion in the vertical direction of the base portion through the base end side of the base portion 62 from the upper and lower protruding seal portions 65 to the harness protection cylinder portion 70 are formed on the surface of the base portion 62. Is formed. The pair of elongate convex portions 67 extend along the extending direction of the upper or lower protruding seal portion 65, respectively. In other words, the pair of elongated protrusions 67 extend while being inclined toward the base end side of the base portion 62 toward the intermediate portion in the vertical direction of the base portion 62. The pair of elongated protrusions 67 intersect at an angle (obtuse angle) so as to protrude toward the base end side of the base part 62 at the center in the vertical direction of the base part 62. Of the pair of elongated projections 67, the side surface 67 f on the base end side of the base portion 62 has a V-shaped side shape that is convex toward the base end side of the base portion 62. The weather strip 19 is disposed so as to cross the surface of the base portion 62 while being bent in a V shape while being pressed against the side surface 67f. Are arranged so as to pass inside the vehicle (see FIG. 10). That is, the protruding seal that can abut on the surface of the side plate 14 at the side position (here, the side position outside the vehicle) where the weather strip 19 passes among the upper and lower side parts that are the outer peripheral part of the base part 62. A portion 65 is protruded.

  Depending on the surface shape of the side plate 14 of the door 10, the surface shape of the side plate T, and the like, the weather strip 19 may be disposed along a route different from the above. For example, the weather strip 19 indicated by a one-dot chain line in FIG. 10 is disposed through a path pressed against the side surface 67f with respect to one (upper) elongated protrusion 67, and the other (lower) elongated protrusion 67. 67 is disposed so as to take a route away from the side surface 67f. In this case, a portion of the side surface 67f formed on one (upper) elongated protrusion 67 serves to guide the weather strip 19 from the harness protection cylinder portion 70 to the vehicle interior side.

  Since the side surface 67f has a V-shaped side surface that is convex toward the base end side of the base portion 62, even if the door grommet 30 is attached to the left-right reverse door 10, the side surface 67f Of these, the lower portion in FIG. 10 is disposed on the upper side and similarly serves to guide the weather strip 19. In this way, the side face 67f has a V-shaped side face shape that is convex toward the base end side of the base portion 62, so that the door grommet 30 is suitable for use in both the left and right doors. be able to.

  In the weather strip 19 disposition path, one (upper) protruding seal portion 65 is in contact with the weather strip 19, and the other (lower) protruding seal portion 65 is away from the weather strip 19. It becomes. In this case, the one (upper) protruding seal portion 65 is relatively easy to be exposed to water, and the corner portion between the protruding seal portion 65 and the base portion 62 and the opposite side of the weather strip 19 has water. Is easy to accumulate. However, since one (upper) protruding seal portion 65 is in contact with the weather strip 19, even in such a state, entry of water through the gap between the side plate 14 and the weather strip 19 is suppressed. it can. Further, the other (downward) protruding seal portion 65 is relatively difficult to get wet, and even if it gets wet, the water flows downward, so that it is difficult for water to collect at the peripheral edge of the protruding seal portion 65. For this reason, even if the other (lower) protruding seal portion 65 is separated from the weather strip 19, the intrusion of water through the gap between the side plate 14 and the weather strip 19 does not pose a problem.

  The weather strip 19 may cross the surface of the base portion linearly. Further, the elongated projection 67 may be omitted.

  In addition, an oval hole 66 is formed in a portion of the grommet main body 60 that is the outward side portion of the side plate 14 and that surrounds the first bolt insertion hole 44 and the second bolt insertion hole 45. The head portion Bt of the bolt B inserted through the first bolt insertion hole 44 and the second bolt insertion hole 45 is disposed in the hole portion 66 and directly contacts the attachment main body portion 42.

  The harness protection cylinder part 70 is formed so as to extend outward from the surface of the base part 62 corresponding to the wire harness lead hole 43. The harness protection cylinder part 70 is formed in a bellows shape, and is formed to be easily bent and stretched. Then, the wire harness WH disposed along the inner surface of the base portion 62 is introduced into the harness protection cylinder portion 70 through the wire harness lead hole 43. Thereby, the harness protection cylinder part 70 covers the wire harness WH drawn out from the wire harness lead-out hole 43. In addition, the base end part by the side of the base part 62 among the harness protection cylinder parts 70 is formed in the shape which becomes thick gradually toward the said base part 62 side. Thereby, when the harness protection cylinder part 70 is bent and deformed, stress concentration on the base end part of the harness protection cylinder part 70 is suppressed, and the breakage of the harness protection cylinder part 70 is suppressed.

  The body side mounting portion 80 is provided at the end of the harness protection cylinder portion 70 and is configured to be mountable in a harness mounting hole formed in the side plate T of the body (see FIG. 2). In addition, this body side mounting part 80 may be abbreviate | omitted.

  The protector 32 is a member formed of resin or the like, and is attached to the surface on the grommet mounting recess 16 side with respect to the body side mounting portion 80. And between the body side mounting part 80 and the protector 32, the wire harness WH is hold | maintained and protected at a fixed position.

  More specifically, the protector 32 has a shape in which peripheral wall portions 34a and 34b protrude from both side portions and one end portion of a bottom plate portion 33 that has a shape obtained by bending an elongated plate-like portion into an L shape. The pair of peripheral wall portions 34a on both sides of the bottom plate portion 33 extend so as to spread outward toward the distal end side, and the peripheral wall portion 34b at one end portion of the bottom plate portion 33 extends outward toward the distal end side. It is extended. When the protector 32 is attached to the inside of the base portion 62, an L-shaped space is formed between the base portion 62 and the protector 32 from the wire harness lead-out hole 43 toward the vehicle inner side blocking portion 50. The wire harness WH is accommodated in the space.

  Further, a protector fixing recess 35 into which the protector fixing piece 43 a can be fitted is formed at one end of the protector 32. On both side portions of the other end portion of the protector 32, protector fixing engaging portions 36 are projected. Then, the protector fixing pieces 43a on the mounting member 40 side are fitted into the protector fixing recesses 35 of the protector 32, and the protector fixing engaging portions 36 are disposed on both sides of the vehicle interior closing portion 50 of the mounting member 40. The protector 32 is mounted and fixed at a fixed position inside the base portion 62 by being disposed so as to contact the inner portion of the protector fixing convex portion 52.

  A wire harness fixing piece 38 is extended to the other end of the protector 32. Here, the wire harness fixing piece 38 is formed in a rectangular plate shape. Then, in a state where the wire harness WH pulled out to the inside of the door grommet 30 is disposed along the wire harness fixing piece 38, an adhesive tape and a binding band are attached to the wire harness WH and the wire harness fixing piece 38. The wire harness WH is held at a fixed position with respect to the door grommet 30 by winding a binding member such as the above.

  The assembly procedure of the door grommet 30 and the wire harness 20 with grommet will be described.

  First, the door grommet 30 in which the mounting member 40 and the grommet body 60 are integrated is prepared. Then, the wire harness WH is inserted through the wire harness lead-out hole 43 and the harness protection cylinder portion 70. Thereafter, the wire harness lead-out hole 43 is bent in an L shape and disposed along the inner surface of the base portion 62 (the surface on the grommet mounting recess 16 side). And the protector 32 is arrange | positioned on the inner surface side of the integrated object of the attachment member 40 and the grommet main body 60 as mentioned above. Then, the wire harness 20 with a grommet provided with the grommet 30 for doors and the wire harness WH arrange | positioned through the harness protection cylinder part 70 is assembled.

  Next, a procedure for assembling the grommet-equipped wire harness 20 to the side portion of the door 10 will be described.

  First, the door grommet 30 is disposed in the grommet mounting recess 16 of the door 10. Then, the bolts B are inserted into the first bolt insertion holes 44 and the second bolt insertion holes 45, and the bolts B are turned to fasten the bolts B to the nuts N inside the side plate 14, respectively. At this time, when one bolt B is bolted using a bolt tightening tool and then the other bolt B is bolted using a bolt tightening tool, the gap between the first bolt insertion hole 44 and the second bolt insertion hole 45 is determined. The space can be used as a work space for bolting. For this reason, the 1st volt | bolt penetration hole 44 and the 2nd volt | bolt penetration hole 45 can be arrange | positioned closely, and the size of the door grommet 30 can be achieved by that much.

  After the door grommet 30 is disposed in the grommet mounting recess 16 and attached to the side plate 14 as described above, the weather strip 19 is moved vertically with respect to the side plate 14 while passing the surface of the door grommet 30. Install along. Then, a pair of projecting seal portions 65 project from the upper and lower positions where the weather strip 19 passes through the outer peripheral portion of the base portion 62, and the pair of projecting seal portions 65 serve as the grommet mounting recess 16. Is pressed against the surface of the side plate 14 on the outer peripheral side.

  FIG. 15 is an explanatory view showing the relationship between the clearance S of the outer peripheral portion of the grommet body 60 and the protruding seal portion 65 in the section taken along line VII-VII in FIG.

  As shown in FIG. 15, when the mounting member 40, which is a rigid member, is mounted on the grommet mounting recess 16, the pressing portion 49 b of the protruding pressing portion 49 causes the portion on the side plate 14 side of the protruding seal portion 65 to be attached by the mounting force. While pressing toward the side plate 14, the inclined portion 49 a of the protruding pressing portion 49 presses the extended ridge seal portion 64 d against the inclined surface around the grommet mounting recess 16. Since the protruding seal portion 65 is formed on the side of the protruding seal portion 65 on the side plate 14 side, the protruding seal portion 65 is pressed against the surface of the side plate 14 while elastically deforming the protruding seal portion 65a. It is done.

  A weather strip 19 is disposed at a position adjacent to the projecting seal portion 65, that is, on the inner side of the vehicle. The outer peripheral seal portion 63 is in contact with the surface of the side plate 14 on the outer peripheral side of the grommet mounting recess 16. Since the outer peripheral seal portion 63 protrudes (slightly protrudes) from the surface of the side plate 14, the weather strip 19 is a portion of the outer peripheral seal portion 63 facing the surface of the side plate 14 from the outer peripheral seal portion 63. Depending on the shape of the protrusion, the deformation may not be possible, and a triangular gap S surrounded by the weather strip 19, the side plate 14, and the outer peripheral seal portion 63 may occur. The protruding seal portion 65 is pressed against the surface of the side plate 14 at a side position of the gap S, here, at a side position outside the vehicle. For this reason, even if the door grommet 30 is flooded from the outside of the vehicle, the water is blocked by the protruding seal portion 65 pressed against the surface of the side plate 14, and direct flooding of the gap S is suppressed. . Thereby, the infiltration of water through the gap S can be suppressed.

  According to the grommet 30 for doors and the wire harness 20 with a grommet comprised as mentioned above, it can contact | abut to the surface of the side plate 14 in the side position of the position where the weather strip 19 passes among the outer peripheral parts of the base part 62. A protruding seal portion 65 is protruded. For this reason, even if there is a gap S between the side plate 14 and the weather strip 19 on the outer peripheral side of the grommet body 60, the gap S is covered by the protruding seal portion 65. Thereby, the infiltration of water through the gap S can be more reliably suppressed.

  In addition, as a configuration for closing the gap S, a configuration in which the gap S is closed by a member that is more flexible than the grommet body 60 (for example, foamed EPDM rubber or the like), a weather strip is reinforced, and the outer peripheral seal portion 63 is strong. The structure etc. which press and make the clearance gap S as small as possible are assumed. However, in these configurations, a separate member that closes the gap S or a reinforcing member that reinforces the weather strip is required, which causes a cost increase. In the present embodiment, since the protruding seal portion 65 is a portion integrally formed with the grommet body 60, the intrusion of water through the gap S can be suppressed at a relatively low cost without using a separate member. There is also an advantage of being able to.

  The protruding seal portion 65 is preferably in contact with the side of the weather strip 19, but this is not essential. This is because even if the protruding seal portion does not contact the weather strip and covers the opening on either side of the gap, the intrusion of water through the gap S can be suppressed.

  Further, it is preferable that the projecting seal portion 65 covers the outside of the gap S, but this is not essential. This is because even if the projecting seal portion is disposed on the vehicle inner side of the gap S, it is possible to prevent water that has passed through the S from entering the vehicle inner side.

  Further, the protruding seal portion 65 is pressed against the surface of the side plate 14 by a protruding pressing portion 49 formed on the mounting member 40 which is a rigid member. For this reason, the protruding seal portion 65 is pressed against the surface of the side plate 14 with a stronger force, and the waterproof sealability between the protruding seal portion 65 and the surface of the side plate 14 can be improved. Thereby, the invasion of water through the gap S can be more reliably suppressed.

  But the protrusion pressing part 49 is abbreviate | omitted and the structure by which a protrusion seal part is pressed on the surface of a side plate by the rigidity of itself may be sufficient.

  Further, since the projecting seal portion 65 includes a projecting seal portion 65a formed with a width narrower than the entire width thereof, the projecting seal portion 65 is pressed against the surface of the side plate 14 while deforming the projecting seal portion 65a. Can do. As a result, the waterproof seal can be more reliably sealed between the protruding seal portion 65 and the surface of the side plate 14, the gap S can be more reliably covered by the protruding seal portion 65, and water enters through the gap S. Can be suppressed more reliably.

  Further, since the ridge seal portion 65a is formed along both the side edge portions and the front end side edge portion of the protruding seal portion 65, the intrusion of water between the protruding seal portion 65 and the surface of the side plate 14 is suppressed. It is possible to suppress the accumulation of water between them.

  However, one or a plurality of ridge seal portions 65 a may be formed along the extending direction of the projecting seal portion 65. Moreover, the protrusion seal | sticker part 65a may be abbreviate | omitted.

  Further, the projecting seal portion 65 is provided so as to project from each of the two lateral positions of the outer peripheral portion of the base portion 62 through which the weather strip 19 passes. For this reason, even when the door grommet 30 is applied to either the left or right door of the vehicle, the same waterproof performance can be obtained at the upper and lower portions. Thereby, the door grommet 30 can be used for both the left and right doors, and the cost can be reduced by sharing parts.

  However, the protruding seal portion 65 may protrude only at a lateral position on one side of the upper and lower positions of the outer peripheral portion of the base portion 62 through which the weather strip 19 passes.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
