The edge of the side wall portion 8 is a free end and goes around the flange 1b side of the rear edge of the front pillar 1, so that it is opened outward as shown by a chain line in FIG. This tendency is likely to occur, and this tendency tends to be remarkable on the upper and lower ends. For this reason, especially at the lower end portion, it is easy to notice when the door is opened (not shown), and the appearance is impaired due to generation of a gap or step between the body side weather strip 6 and the edge of the side wall portion 8.

In addition to such thermal deformation with time, the opening may also be caused by the positional deviation of the clip 10 and the mounting hole 11.
If the lower end is made to match the side edge of the instrument panel 13 as described above, as in the pillar garnish 7, the assembly error and the molding error of the instrument panel 13 and the front pillar 1 cause If the instrument panel 13 is displaced relative to the pillar garnish 7 in the vehicle width direction or in the front-rear direction, the same opening phenomenon as described above may occur at the lower end of the side wall portion 8 and the quality may be impaired.

Therefore, the present invention does not cause the opening of the side wall edge of the pillar garnish due to temporal thermal deformation, molding error, mounting error, etc.
An object of the present invention is to provide a pillar garnish mounting structure for an automobile, which can further enhance the sense of quality and improve reliability.

[0008]

A locating hole is formed in a flange of the pillar in a structure in which a side wall portion extending around a flange side of the pillar is integrally extended with a pillar garnish mounted vertically along a pillar inner. On the other hand, a hook portion that fits into the locate hole is formed on a side wall portion of the pillar garnish, and a claw portion that engages with the flange edge is formed on an edge of the side wall portion. The portion is engaged with the corresponding locate hole and flange edge, and a thin flexible portion is formed at a continuous portion of the side wall portion of the pillar garnish.

[0009]

The positioning in the up-down direction and the front-rear direction is performed by the engagement between the hook portion and the locate hole, and the positioning in the vehicle width direction is performed by the engagement between the claw portion and the flange edge. The opening is suppressed.
In addition, the displacement of the pillar garnish in the front-rear direction and the vehicle width direction due to a mounting error between the pillar garnish and the pillar inner or other vehicle body-side members is absorbed by the elastic deformation of the flexible portion, and the hook portion and the hook portion are engaged. And acting as an external force in the detaching direction.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a conventional pillar according to an embodiment of the present invention; FIG.

1 to 3, a pillar garnish 7 for concealing a pillar inner 2 of a front pillar 1 has a side wall portion 8 extending to a flange 1 b side of a rear edge of the front pillar 1 and integrally extending therefrom. Pillar garnish 7
Basically, a plurality of clips 10 provided in the vertical direction on the back surface thereof are fitted and fixed in the mounting holes 11 of the pillar inner 2, and the hooks 12 projecting from the lower edge of the pillar garnish 7 are Basic configuration such that the lower end of the pillar garnish 7 is fitted closely to the side edge of the instrument panel 13 to fit them into the locate hole 14 provided on the side edge of the instrument panel 13 so that they are aligned. Is the same as in the prior art.

At the lower edge of the side wall 8 of the pillar garnish 7, a pair of claws 15 are formed to be engaged with the flange 1b of the rear edge of the front pillar 1. A hook 16 is integrally formed at a position facing the flange 1b between the flanges 15 and 15, and a locate hole 17 into which the hook 16 is fitted is formed at a position corresponding to the hook 16 on the flange 1b. Formed
These claws 15 and hooks 16 are connected to the corresponding flanges 1.
The edge b is engaged with the locate hole 17.

Further, a thin flexible portion 18 is formed at a continuous portion of the side wall portion 8 of the pillar garnish 7, and the flexible portion 1 is formed.
The elastic deformation of the pillar garnish 7 can absorb the displacement of the pillar garnish 7 in the front-rear direction and the vehicle width direction.

According to the structure of the above embodiment, the hook 16
Of the side wall portion 8 by the engagement of the
The positioning in the vehicle width direction of the side wall portion 8 is performed by the engagement between the claw portion 15 and the edge of the flange 1b, and the opening of the side wall portion 8 of the pillar garnish 7 is opened. The opening of the lower end portion of the side wall portion 8 where the tendency is large is suppressed, and the end of the side wall portion 8 and the body side weather strip 6 attached to the outer portion of the flange 1b are suppressed.
A gap or a step between them can be avoided.

Further, the hook 1 may be displaced due to an assembly error of the vehicle body, a molding error of the instrument panel 13 or an assembly error.
Even when the lower end portion of the pillar garnish 7 connected to the side edge of the instrument panel 13 due to the engagement between the lug 2 and the locate hole 14 is displaced in the front-rear direction or the vehicle width direction, this displacement may occur. Is absorbed by the elastic deformation of the flexible portion 18 formed at the continuous portion of the side wall portion 8, and the displacement load due to the displacement is engaged with the hook portion 16 and the locate hole 17, and the claw portion 15 and the flange 1b
