DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a door body.
On the front side of the door waist W, a corner piece 2 having a substantially triangular side surface is provided. The corner piece 2 is composed of a base 3 made of a metal plate and a cover 4 made of an elastic material integrally molded on the outer side surface of the base 3.

A door mirror body 5 is rotatably mounted on a door mirror side bracket 6 formed in the same triangular shape as the corner piece 2. On the back of the door mirror side bracket 6,
Boss portions 7 for screwing bolts are protrudingly provided at a total of three locations, that is, a front portion and a rear portion at the lower side, and in the present embodiment, the boss portion 7 in the present embodiment has a radial direction at an end edge of the upper boss portion 7. For example, a locking projection 8 extends upward, for example.

On the other hand, the boss 7
The boss insertion holes 9 are formed at three upper and lower positions corresponding to the above.
A notch is formed in the upper boss insertion hole 9 corresponding to the boss portion 7 having the locking projection 8 formed on the side of the cover 4 at the boundary between the base 3 and the cover 4. Piece 8
Is formed.

According to the structure of the embodiment described above, when assembling the door mirror body 5 to the corner piece 2, FIG.
By tilting the door mirror side bracket 6 as shown by the chain line, the boss portion 7 having the locking projection 8 is twisted obliquely from the cover 4 side into the boss insertion hole 9 on the upper side of the corner piece 2, and The insertion hole 9 is elastically deformed, and the tip of the boss portion 7 on which the locking projection 8 is formed is advanced into the boss insertion hole 9 while rotating the door mirror side bracket 6 downward.
The locking projection 8 enters the groove 10 and is locked. Along with the insertion of the upper boss 7 into the boss insertion hole 9, the lower boss 7 is also inserted into the boss insertion hole 9. When these bosses 7 are inserted into the boss insertion holes 9, the locking projections 8 of the upper boss 7 are engaged with the grooves 10, and the cover 4 is pressed against the door mirror side bracket 6 by a reaction force against the grooves 10. The locking projection 8 is reliably prevented from coming off and floating with the base 3, and the lower boss 7 is also restrained from floating in the boss insertion hole 9 of the cover 4 in the radial direction. Can be temporarily fixed to the corner piece 2 stably. Therefore, the worker inserts the bolt 11 into the boss insertion hole 9 from the cabin side of the corner piece 2 and screws it into the boss portion 7 without manually supporting the temporarily fixed door mirror body 5, and the door mirror side bracket 6 may be fastened to the corner piece 2.

In the above-described embodiment, the locking projection 8 is formed upward on the upper boss 7. However, as shown in FIGS. While the small locking projection 8a is extended, the groove 1 is formed in the corresponding lower boss insertion hole 9 at the boundary between the base 3 and the cover 4 at the cover 4 side.
The notch 0a may be formed, and the locking projection 8 and the groove 10a may be engaged with each other to perform more stable temporary fixing. In the case of this embodiment, the locking projection 8a of the lower boss 7 has a small amount of protrusion, so that even if it is simply pushed into the boss insertion hole 9 of the cover 4 in the axial direction, the boss insertion hole 9 is not inserted. It can be elastically deformed without much resistance and can be easily inserted and engaged with the groove 10a.

[0014]

As described above, according to the present invention, the locking projection formed at least at the edge of the upper boss on the rear side of the door mirror side bracket is connected to the base of the bolt insertion hole of the corner piece and the elastic material cover. By elastically engaging with the groove formed on the cover side of the boundary portion, the movement of the locking protruding piece between the base and the groove in the pullout direction and the floating in the radial direction are reliably restrained, and Since the lower boss also suppresses radial movement in the boss insertion hole,
The door mirror body can be temporarily fixed to the corner piece stably. As a result, it is not necessary to support the door mirror body by hand, the bolt can be easily screwed into the boss portion, and the door mirror side bracket can be easily fastened to the corner piece, thereby significantly improving the door mirror assembling workability. be able to. In addition, the elasticity of the locking projection and the groove
The temporary fixing function by the temporary locking
Although it will lose its function,
The final fixed holding force of the door mirror side bracket is three
As it depends on the fastening force of the bolt, it is the same as before
Or more firmly with a fixed holding force and more
This has the effect that the door mirror side bracket can be fixed stably.
