Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mirror holder support member mounting structure for a rearview mirror.

(Prior Art) In a back mirror, a mirror holder is supported by a mirror holder support member, and the mirror holder support member is attached to a bracket of the mirror body.

By the way, if the mirror supported by the mirror holder is damaged, it would be expensive to replace the entire back mirror, so remove the mirror holder support member that supports the mirror holder from the bracket, and then replace the mirror holder with the mirror holder support member. There is a mirror holder that can be removed and replaced with a new mirror attached. For this purpose, the mirror holder support member is removably attached to the bracket.

Examples of the mounting structure for such a mirror holder support member include Japanese Utility Model Publication No. 63-37321 and Japanese Utility Model Publication No. 37321/1983.
The disclosure is in the publication No. 62-170346.

In the example shown in Japanese Utility Model Publication No. 63-37321, a locking hole is formed in the upper part of the mirror holder support member, and a screw threading part is provided at the lower end, and the locking hole locks a claw formed in the bracket. The mirror holder support member is attached to the bracket by tightening the screw threaded portion and the lower part of the bracket with screws.

Furthermore, in the example shown in Japanese Utility Model Application No. 63-170346, a metal plate is arranged on the rear surface of the mirror holder support member, and this plate and the mirror holder support member are fastened together with a plurality of screws. The mirror holder support member is attached by locking the claw provided on the upper part to the bracket and fixing the lower part to the bracket side with screws from below.

(Problems to be Solved by the Invention) However, the mounting structure for the mirror holder support member as described above has the following problems.

In the example disclosed in Japanese Utility Model Publication No. 63-37321, the upper and lower parts of the mirror holder support member are fixed with claws and screws, so that the difference in thermal expansion between the bracket and the mirror holder support member cannot be absorbed.

Furthermore, in the example of Japanese Utility Model Application Publication No. 62-170346, an iron plate is attached, which increases the manufacturing process, and the lower part of the iron plate is attached from below with screws, so this lower part tends to wobble in the horizontal direction. .

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to provide a back mirror that can effectively absorb the difference in thermal expansion between the bracket and the mirror holder support member, requires fewer manufacturing steps, and does not wobble. The present invention provides a mirror holder support member mounting structure.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a mirror holder support member attachment structure for a back mirror in which a mirror holder support member is attached to a bracket on the side of the mirror body, in which a frame is provided on the bracket and the frame is attached to the frame. An insertion section for inserting the mirror holder support member into the body is provided, a locking section for locking the mirror holder support member is provided on one side of the frame, and a mounting means is provided on the other side of the frame for the insertion section. an elastic member that can be freely retracted and retracted, a contact surface between the mirror holder support member and the elastic member is a slope, and the mirror holder support member is biased diagonally inward by the elastic member and attached to the bracket. It is characterized by

(Function) Since the mirror holder support member is biased obliquely inward and attached by the elastic member, the difference in thermal expansion and contraction between the bracket and the mirror holder support member can be absorbed by the elastic member. Further, since there is no need to provide a metal plate on the rear surface of the mirror holder support member as in the prior art, the number of manufacturing steps can be reduced. Furthermore, since the elastic member biases the mirror holder support member obliquely, the mirror holder support member does not wobble in either the vertical direction or the front-back direction.

(Embodiment) A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

Fig. 1 is a front view of the rear mirror, Fig. 2 is a plan view thereof, Fig. 3 is a longitudinal sectional view thereof, Fig. 4 is a longitudinal sectional view of the bracket, Fig. 5 is a view of the bracket drawn from diagonally from the front, Figure 6 is a view of the bracket viewed obliquely from the rear.

In the figure, 1 is a base member fixed to the vehicle body side, 2 is a metal bracket whose base end is rotatably attached to the base member 1, 3 is a mirror holder support member made of synthetic resin, and 4 is a metal bracket that is rotatably attached to the base member 1. The mirror holder H is supported by the mirror holder support member 3 and supports the mirror M, and H is a housing. As shown in FIGS. 5 and 6, a cylindrical engaging portion 2a is formed on the base end side of the bracket 2.
The bracket 2 is rotatably engaged with a fixed shaft fixed on the side of the base member 1 of a, and the bracket 2 is configured to be rotatable with respect to the base member 1 as described above. Further, a frame body 2b is provided on the tip side of the bracket 2, and this frame body 2b has an upper part 2b1, left and right side parts 2b2 and 2b3, and an upper part 2b.

Second locking portions 6, 6, 6 are provided on each inner surface of the inclined portion 2b4.
are integrally formed.

A support surface portion 8 is integrally formed on the back side of the frame 2b, and a space S for attaching the mirror holder support member 3 is formed between the inside of the frame 2 and the support surface portion 8, and this space S constitutes an insertion portion. do. Further, a flange 8a projecting forward is integrally formed at the lower end of the support surface portion 8, and an elastic plate 10, which will be described later, is attached to this flange 8a.

The front surface of the mirror holder support member 3 is provided with a support portion 3a for supporting the mirror holder 3, and operating rods 3b, 3b that are engaged with the mirror holder 3 and are moved in and out by the power of a motor (not shown). The mirror holder support member 3 is connected to the space S.
The front edge of the upper part 3c is locked to the first locking part 5, the rear part is locked to the second locking part 6, 6, 6, and the lower part 3e is locked to the elastic plate 10. do.

FIG. 7 is a plan view of the elastic plate 10, and FIG. 8 is a cross-sectional view taken along the - line in FIG. 7. As shown in these figures, the elastic plate 10 includes a main body 10a and
The upright piece 10 is formed by standing upward from the side of the
