BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an external view of a vehicle including a door to which a seal part is attached by a mounting structure for a seal part of a vehicle door according to an embodiment of the present invention. It is a disassembled explanatory drawing explaining schematic structure of a rear door. It is the III-III arrow directional view in FIG. FIG. 4 is a detailed view of an arrow IV part in FIG. 3.

  FIG. 1 shows an overall appearance of a vehicle including a door (rear door) to which a sealing part is attached by a mounting structure of a sealing part for a vehicle door according to an embodiment of the present invention, and FIG. 2 shows the door in FIG. FIG. 3 shows a cross-sectional view of a portion of the garnish 3 as viewed in the direction of arrows III-III in FIG. 1.

  As shown in FIG. 1, for example, a garnish 3 and a garnish 4 made of hard resin are provided in the window frame portion of the rear door 2 of the vehicle 1, and a garnish 6 is arranged at the rear portion of the front door 5. ing. When the rear door 2 is closed, the garnish 3 and the garnish 6 are arranged on the same surface (to be flush with each other), and the design is maintained.

  As shown in FIG. 2, the rear door 2 includes a rear door inner panel 11 and a rear door outer panel 12, and a garnish 3 is fitted and fixed to the outside of the rear door outer panel 12 on the front side of the window frame portion 13. The garnish 4 is fitted and fixed to the outside of the rear door outer panel 12 on the rear side of the window frame 13.

  For example, a first run channel 15 formed of a soft resin or the like is disposed as a sealing part from the front side of the garnish 3 to the rear side of the garnish 4, and extends from the front side of the garnish 3 to the rear side of the garnish 4, for example, A second run channel 16 formed of a soft resin or the like is disposed. A part of the edge of the opening on the vehicle body side where the rear door 2 is disposed is closed by the first run channel 15.

  As shown in FIG. 3, the garnish 3 is fitted into an edge 12a where the rear door inner panel 11 and the rear door outer panel 12 are combined, and is fixed to the rear door outer panel 12 (edge 12a) with, for example, an adhesive tape (not shown). The

  An opening 21 having a U-shaped cross section is formed along the edge at the front edge of the garnish 3. A fitting portion 22 of the first run channel 15 is inserted and held in the opening 21. On the front side of the first run channel 15 (on the rear side of the first run channel 15 of the garnish 4), a lip portion 23 is provided continuously to the fitting portion 22, and the lip portion 23 is an edge of the garnish 6 on the passenger compartment side. Abut. The edge of the garnish 6 on the front door side is closed by the lip 23 of the first run channel 15.

  In the structure for mounting the seal part (first run channel 15) of the vehicle door (rear door 2) described above, the width of the opening 21 of the garnish 3 is narrower than the width of the fitting portion 22 of the first run channel 15. Is formed. In this case, it is narrowly formed with a dimensional difference larger than the manufacturing variation.

  For this reason, when the fitting part 22 is inserted in the opening part 21 of the garnish 3, the fitting part 22 is engaged with the opening part 21 in a state where the bending state is maintained in the opening part 21 and elastically deformed. The holding force of the first run channel 15 is ensured. As a result, the holding force of the first run channel 15 is maintained regardless of whether the force in the direction pulled from the opening 21 is applied to the first run channel 15 or the force in the rotating direction is applied to the opening 21. Secured.

  For this reason, it is not necessary to use parts such as a clip and a joining member, and the first run channel 15 is attached to the garnish 3 in a state in which a holding force is secured against a force that works from an arbitrary direction without increasing the cost. It becomes possible.

  The first run channel 15 can be attached to the garnish 4 with the same configuration. In addition, the structure of this embodiment can be applied as a configuration for attaching a seal component other than a run channel, such as a weather strip. In particular, the first run channel 15 of the garnish 4 is easy to apply force in any direction by touching the body and luggage when the passenger gets on and off, but can hold the first run channel 15 reliably, The first run channel 15 does not come off.

  The seal part mounting structure will be described in detail with reference to FIG. FIG. 4 shows a detailed situation of an arrow IV portion in FIG. 3, and is a cross section in a state where the fitting portion 22 of the first run channel 15 is held in the opening 21 on the front side of the garnish 3. The present embodiment will be described in detail by taking as an example the attachment of the first run channel 15 to the garnish 3.

  As shown in the figure, the fitting portion 22 of the first run channel 15 is formed with a wide portion 25 at the tip, and the end portion in the width direction of the wide portion 25 is behind the insertion direction into the opening portion 21 (see FIG. (Middle left) The fitting portion 22 on the base side of the wide portion 25 has a narrow width, and the bending operation of the wide portion 25 is facilitated. As indicated by a two-dot dotted line in the figure, the width X of the wide portion 25 before being inserted into the opening 21 is made wider than the width Y of the opening 21. That is, the width Y of the opening 21 is formed narrower than the width of the fitting portion 22 of the first run channel 15 (the width X of the wide portion 25).

  When the wide portion 25 of the fitting portion 22 of the first run channel 15 is fitted into the opening portion 21 of the garnish 3, the wide portion 25 of the fitting portion 22 is reliably elastically deformed (state indicated by a solid line in the figure). The fitting part 22 is held in the opening part 21. Further, since the end portion of the wide portion 25 in the width direction is directed to the rear side in the insertion direction into the opening portion 21, the movement of the wide portion 25 in the direction away from the opening portion 21 (the first run channel 15 of the first run channel 15). The movement of the fitting portion 22 is reliably regulated.

  On the other hand, a protrusion 26 protruding inward is formed at the opening 21 of the garnish 3 on the rear side of the wide portion 25 of the fitting portion 22 of the first run channel 15, that is, at the entrance of the opening 21 of the garnish 3. Is formed. Since the protrusion 26 is formed at the entrance of the opening 21, in the unlikely event that multiple forces or large forces act on the first run channel 15, the fitting portion 22 moves away from the opening 21. Even so, the tip portion of the wide portion 25 is locked to the protrusion 26. Thereby, the movement of the fitting part 22 is controlled and the first run channel 15 is not detached from the garnish 3.

  The mounting structure of the vehicle door seal part described above attaches the first run channel 15 to the garnish 3 in a state in which the holding force is secured against the force acting from any direction without increasing the cost. Is possible.
