In the pillar trim of Patent Document 2, when one bolt fixing portion is replaced with a clip seat and a pillar trim mounting structure using both a clip and a bolt is used, the bolt fixing portion is fixed to the pillar portion by a bolt prior to fixing the bolt fixing portion to the pillar portion. Then, fix the pillar trim to the pillar part with a clip. At that time, in order to enable smooth and easy mounting work of the pillar trim, the bolt is temporarily held by the pillar trim by fitting a retaining washer to the shaft portion of the bolt through which the bolt fixing portion has been penetrated in advance. ..

In the pillar trim mounting work, in order to fix the pillar trim to the pillar portion by the clip, the clip attached to the clip seat is fitted into the hole of the pillar portion. For that purpose, the clip seat is formed by tapping the pillar trim from the passenger compartment side (the side opposite to the pillar portion) toward the pillar portion. At this time, the impact force of the tapping is transmitted to the bolt fixing part, or the part between the clip seat and the bolt fixing part is hit, and the temporarily held bolt pops out from the bolt fixing part in the axial direction and falls off. There was something.

In order to solve the above problems, the present invention includes a clip seat and a bolt fixing portion formed integrally with the pillar trim at the end of the pillar trim, and the clip seat and the bolt fixing portion are arranged apart from each other. In a structure in which the pillar trim is attached to the pillar portion of the vehicle body panel by using the clip attached to the clip seat and the bolt penetrating the bolt fixing portion, the shaft portion of the bolt is fixed to the bolt. It penetrates the portion and is temporarily held in a state where a retaining washer is fitted to the shaft portion, and a notch is formed between the clip seat and the bolt fixing portion.

According to the above configuration, a notch is formed between the clip seat and the bolt fixing portion when the formation portion of the clip seat is struck from the passenger compartment side of the pillar trim toward the pillar portion due to the mounting of the pillar trim by the clip. By doing so, the portion between the clip seat and the bolt fixing portion is not hit, and the formed portion of the clip seat is surely hit. The impact force generated by hitting the clip seat into the formed portion is weakened by the notch and transmitted to the bolt fixing portion. Therefore, it is possible to prevent the bolt temporarily held by the bolt fixing portion from falling off.

Preferably, the clip seat and the bolt fixing portion are arranged at the lower end portion of the pillar trim so as to be separated from each other in the vehicle length direction.
According to the above configuration, the impact force when the clip seat is driven into the formed portion bypasses the notch from the clip seat and is transmitted to the bolt fixing portion located at a position away from the clip seat in the vehicle length direction. As a result, the impact force is dispersed and weakened, so that the bolt temporarily held by the bolt fixing portion can be prevented from falling off.

According to the present invention, it is possible to provide a mounting structure of a pillar trim that prevents the temporarily held bolt from falling off.

A reinforcing rib 44 is provided on the rear side of the clip seat 41 in the vehicle length direction, and is connected to the seat plate portion 43 and the upper wall and the lower wall of the side plate portion 42.

A clip 60 is attached to the clip mounting hole 43a from below and fixed at the upper end. This clip 60 is well known, and when it is attached to the pillar panel 20 of the front leg portion 40, the tip side (outside of the vehicle in the vehicle width direction) of the clip 60 is the clip locking hole (not shown) of the pillar panel 20. ) Is fitted to the pillar panel 20 in a well-known manner.

Next, a structure for mounting the rear leg portion 50 to the pillar panel 20 using the bolt 70 will be described.
As shown in FIGS. 1 to 3, the bolt 70 used in this embodiment has a flange portion 71 at the head portion and a screw portion formed on the tip end side of the shaft portion 72. A bolt without a flange may be used.

As shown in FIGS. 1 and 2, the rear leg portion 50 extends downward from the front leg portion 40. The lower end portion 50A of the rear side leg portion 50 is formed in a thin plate shape and is located below the clip seat 41 of the front side leg portion 40. As shown in FIGS. 1 to 3, a bolt fixing portion 51 is provided at the lower end portion 50A.

The bolt fixing portion 51 is formed with a slit 52 that penetrates the thin plate-shaped lower end portion 50A of the rear side leg portion 50 in the vehicle width direction and extends in the vertical direction. The upper and lower ends of the slit 52 have a semicircular shape. The seat surface support portion 53 is provided so as to project toward the vehicle interior side so as to be along the opening edge of the slit 52 on the vehicle interior side. As shown in FIG. 3, the shaft portion 72 of the bolt 70 is inserted into the slit 52, and the seat surface support portion 53 abuts on the seat surface of the flange portion 71 on the shaft portion 72 side to support the bolt 70.
As shown in FIG. 2, on the vehicle interior side of the lower end portion 50A of the rear side leg portion 50, a reinforcing rib 54 is provided on the rear side in the vehicle length direction adjacent to the bolt fixing portion 51.

As shown in FIG. 3A, when the rear leg portion 50 is mounted on the pillar panel 20 using the bolt 70, the shaft portion 72 is passed through the slit 52 at the upper end portion of the bolt fixing portion 51 from the vehicle interior side. The bolt 70 is screwed into the screwed portion 21 of the pillar panel 20 and fixed.

As shown in FIG. 3B, in the bolt fixing portion 51, the bolt 70 is temporarily held in the bolt fixing portion 51 in advance so that the pillar trim 10 can be smoothly and easily attached to the pillar panel 20. I can let you.

Temporary holding of the bolt 70 by the bolt fixing portion 51 will be described.
The shaft portion 72 of the bolt 70 is passed through the slit 52 at the lower end of the bolt fixing portion 51 from the vehicle interior side, and the seat surface of the flange portion 71 is brought into contact with the seat surface support portion 53. In this state, the setting washer 80 (retaining washer) is attached to the shaft portion 72 so as to be separated from the back surface (outside surface of the vehicle) of the rear side leg portion 50. The setting washer 80 is made of paper and is formed in an annular shape, and has a protrusion 81 protruding toward the center of the setting washer 80 along the inner circumference thereof. Since the protrusion 81 is bitten into the threaded portion of the shaft portion 72 and the shaft portion 72 is press-fitted into the setting washer 80, the bolt 70 is prevented from coming off from the slit 52. In this way, the bolt 70 is temporarily held at the lower end of the bolt fixing portion 51 in the pillar trim 10. The setting washer 80 may be made of resin, metal, or other material.

Next, the work of attaching the pillar trim 10 to the pillar panel 20 will be described.
First, prior to the mounting work, the bolt 70 is temporarily held by the pillar trim 10 by the method described above.

At this time, the pillar trim 10 is aligned with the pillar panel 20 and the upper portion is fixed, and the formed portion of the clip seat 41 on the front leg portion 40 is driven toward the pillar panel 20 from the vehicle interior side. ..

Since the portion between the clip seat 41 of the front leg 40 and the bolt fixing portion 51 of the rear leg 50 is cut off by the notch 11c on the rear side of the clip seat 41 in the vehicle length direction, this portion is hit. Since there is no such thing, the formed portion of the clip seat 41 of the front leg portion 40 can be accurately hit.

The impact force generated by tapping the front leg 40 into the formed portion of the clip seat 41 bypasses the notch 11c from the clip seat 41, passes through the front wall 11, and reaches the rear leg 50 rearward in the vehicle length direction. It is transmitted to the bolt fixing portion 51 below the clip seat 41. That is, since the impact force is not transmitted to the bolt fixing portion 51 at the shortest distance but is dispersed and weakened by the notch 11c, it is possible to prevent the bolt 70 temporarily held by the bolt fixing portion 51 from falling off.

After the fixing work of the front leg portion 40 by the clip 60 is completed, the rear leg portion 50 of the pillar trim 10 is fixed to the pillar panel 20 by using the bolt 70.
As shown in FIG. 3B, when the upper portion of the pillar trim 10 and the front leg portion 40 are fixed to the pillar panel 20, the pillar trim 10 is twisted and deformed, so that the rear leg portion 50 and the pillar panel 20 are twisted and deformed. There is a slight gap G between and. The temporarily held bolt 70 is located at the lower end of the bolt fixing portion 51. The bolt 70 is moved to the upper end of the bolt fixing portion 51 along the slit 52 without removing the setting washer 80. As shown in FIG. 3A, by screwing the bolt 70 into the screwed portion 21 of the pillar panel 20, the rear leg portion 50 is fixed to the pillar panel 20 by the bolt 70, and thus the pillar trim 10 is the pillar panel. It is attached to 20.

After the pillar trim 10 is attached to the pillar panel 20, the upper end portion of another pillar trim 30 (not shown) is overlapped and assembled from the vehicle interior side to the lower end portion 10A of the pillar trim 10 by the method described above. As a result, the clip seat 41 and the bolt fixing portion 51 arranged at the lower end portion 10A of the pillar trim 10 are shielded from the vehicle interior by another pillar trim 30, and are not visible from the vehicle interior.

The present invention is not limited to the above embodiment, and various modifications can be adopted without departing from the gist thereof.
A bolt fixing portion may be provided on the front leg portion, and a clip seat may be provided on the rear leg portion.
The clip seat and the bolt fixing portion may be provided at an end portion other than the lower end portion of the pillar trim.
