Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention relates to vehicle mirrors, and more particularly to
The present invention relates to a vehicle mirror in which a mirror body is mounted on a rod-shaped stay fixed to a vehicle body.

[0002]

2. Description of the Related Art Conventionally, for example, as shown in FIG. 6 (A), a mirror body 2 is attached to a middle portion of a rod-shaped stay 1 and both ends of the stay 1 are fixed to a vehicle body (both not shown). A known mirror 3 for a vehicle has been known (Shokai 62-862).
49).

As shown in FIG. 6B, the mirror body 2 is located in a housing 4, a cover 5 that closes the rear opening of the housing 4, and a space P formed by the housing 4 and the cover 5. The base 6 fixed to the housing 4
And a bracket 8 that is fixed to the base 6 with screws 7 and holds the stay 1 therebetween.

The bracket 8 is, for example, as shown in FIG. 6 (C), screw holes 8 formed at both ends of a thin metal plate.
a and 8b, and a tongue piece 8 formed in a cut-and-raised shape in the middle
c, a screw hole 8d for inserting the screw 7 formed in the tongue piece 8c, and a holding portion 8e in which both ends and a portion excluding the tongue piece 8c are bent into an annular shape.

Further, in such a structure, after fixing the bracket 8 with the screw 7, the stay 1 is penetrated into the space P and at the same time the stay 1 is positioned in the holding portion 8e.
From this state, the screw holes 8a and 8b are aligned with each other, the screws 9 are inserted into the screw holes 8a and 8b, and the screws 9 are screwed into the housing 4 or the base 6, so that the bracket 8 tightens the stay 1. Sandwich between.

Further, the stay 1 by the bracket 8
After securing the holding force of the mirror body 2 to the stay 1 by tightening, the rear opening of the housing 4 is closed by the cover 5, and the mounting of the mirror body 2 to the stay 1 is completed.

By the way, in such a structure, when the stay 1 is directly tightened by the bracket 8, the holding portion 8 is adjusted depending on the degree of tightening adjustment of the bracket 8 by the screw 9.
Although the inner diameter of e varies, the change of the inner diameter is not the change of the inner diameter of the portion in contact with the stay 1 evenly approaching the center direction (the shape does not become a perfect circle), and thus the stay is not formed. Not only does the bracket 8 not come into uniform contact with the bracket 1, but there is also a problem that the bracket 1 scratches the stay 1.

Therefore, for example, resinous arc-shaped holders 10, 10 divided into two equal parts are interposed between the bracket 8 and the stay 1, and the elasticity thereof makes the portion abutting on the stay 1 uniform and uniform. It is possible to prevent damage.

This holder 10 is shown in FIGS. 7 (A)-(C).
As shown in FIG. 5, the bracket 8 is mounted on the outer wall of which a pair of upper and lower protrusions 10a, 10a are formed.

The pair of projections 10a, 10a are used for positioning with respect to the bracket 8, and the bracket 8 is formed with holes 8e, 8e into which the projections 10a, 10a are inserted.

[0011]

By the way, in the vehicle mirror 3 configured as described above, the holder 10,
Since 10 can fully exhibit its role only by being interposed between the stay 1 and the bracket 8,
The structure is such that it is sufficient if the positioning is made to some extent.

However, since the holders 10, 10 cannot be fixed to the bracket 8 or the stay 1 before fixing the bracket 8 to the base 6, after the stay 1 is positioned in the holding portion 8e, the holding portion 8e is held. The complicated manual work of interposing the holders 10 in the gap between the stay 1 and the stay 1 in a positioned state and screwing the screws 9 thereon has to be performed in the narrow space P. Moreover,
After interposing one holder 10, the other holder 1
During the work of interposing 0, there was a problem that one holder 10 was displaced or dropped.

The outer diameters of the protrusions 10a, 10a and the holes 8e,
Processed so that the inner diameter of 8e is the same, and the protrusion 10a,
It is conceivable that the bracket 8 holds the holder 8 by press-fitting 10a into the holes 8e, 8e, but in this case,
There is a problem that the reliability is low because a dimensional error occurs during molding of both.

The present invention has been made in view of the above circumstances, and not only can the workability be improved, but also the vehicle can be prevented from being dropped or misaligned and the reliability can be improved. It is intended to provide a mirror for use.

[0015]

In order to achieve the object, the invention described in claim 1 is a vehicle in which a bracket is fixed in a mirror body, and a rod-shaped stay fixed to a vehicle body is sandwiched by the bracket. In the mirror for use, a plurality of holders are interposed between the stay and the bracket, an engagement hole is formed in the bracket, and an engagement claw that elastically engages the engagement hole is provided in the plurality of holders. What is formed is the gist.

[0016]

According to the structure of the first aspect,
The bracket is fixed in the mirror body, the engaging hole is formed in the bracket, the engaging claws that elastically engage with the engaging hole are formed in the plurality of holders, and the holder is fixed to the vehicle body so that the holders are located between them. The rod-shaped stay thus formed is clamped by the bracket.
