DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a harness retaining structure in a vehicle rearview mirror according to the present invention will be described below with reference to FIGS.
This will be described with reference to FIG. In the drawing, the same reference numerals as those in FIGS. 5 and 6 denote the same components. In the illustrated example, an electric retractable door mirror device of an automobile will be described. It should be noted that hatching is omitted in the reading of the drawings. In the figure, reference numeral 8 denotes a tube into which the first harness 5 and the second harness 6 are inserted,
The tube 8 has, for example, a rubber-like elastic cylindrical tube shape.

In this embodiment, the screw 40 is screwed into the boss 310 which is integrally formed in the mirror housing 31 via the bracket 4 so that the bracket 4 separate from the mirror housing 31 is screwed.
Thus, a space is provided between the mirror housing 31 and the mirror housing 31 through the space 0 to be fixed. The bracket 4 may be fixed in the mirror housing 31 by welding or the like in addition to the screw 40.

Of the opposing surfaces of the mirror housing 31 and the bracket 4 described above, a projection 41 is integrally formed above the opposing surface of the bracket 4. As a result, a press-fitting opening 42 is formed between the above-mentioned convex portion 41 and the facing surface of the mirror housing 31. This press-fit opening 4
The opening width of No. 2 is smaller than the outer diameter (outer width) of the tube 8 described above. Further, the above-mentioned convex portion 41 has a shape in which the tube 8 is easily press-fitted into the press-fitting opening portion 42 and is hard to be pulled out from the press-fitting opening portion 42, that is, a hook shape in which the outer surface has a semicircular shape and the inner surface has a planar shape. Make

An abutment surface 80 is provided on a surface (rearward) of the mirror housing 31 and the bracket 4 deeper (lower) than the above-described press-fit opening 42 and on an upper surface of the boss 310. The abutting surface 80 is a member in which the above-described tube 8 that has been elastically deformed and then elastically restored after being press-fitted through the above-described press-fitting opening 42 is elastically abutted, and the harnesses 5 and 6 are stopped in the mirror housing 31. It is.

The structure for stopping the harness of the present invention in this embodiment has the above-described structure, and a method of stopping the harnesses 5 and 6 will be described below. First, the tube 8 into which the harnesses 5 and 6 are inserted is inserted into the press-fitting opening 42.
(See FIG. 4 (A)), whereupon the tube 8 is crushed flat against the elasticity of the tube 8 and elastically deformed (see FIG. 4 (B)), and is elastically deformed. In this state, the tube 8 is press-fitted along the inner surface of the mirror housing 31 into the stop space surrounded by the contact surface 80 via the press-fitting opening 42 between the inner surface of the mirror housing 31 and the convex portion 41 of the bracket 4. (See FIG. 4C). When the elastically deforming force is released from the tube 8, the elastically deformed tube 8 is elastically returned to the original state (cylindrical tube state) as shown in FIG.
As a result, the harnesses 5, 6 and the tube 8 are fixed in the mirror housing 31.
That is, as shown in FIGS. 4 (B) and 4 (C), the tube 8 is pressed flat and the mirror housing 3 is closed.
If the harnesses 5, 6 and the tube 8 are not pulled out from the press-fitting opening 42 between the inner surface of the mirror housing 31 and the convex portion 41 of the bracket 4 along the inner surface of the mirror housing 31, the space between the mirror housing 31 and the bracket 4 Not come off.

As described above, in the harness retaining structure of the present invention in this embodiment, the opposing surface of the mirror housing 31 and the bracket 4 and the upper surface of the boss 310 are formed as the contact surface 80 on which the tube 8 elastically contacts. And bracket 4
Is provided with the projection 41 for forming the press-fitting opening 42 on the opposite surface of the bracket 4, compared with a conventional harness stopper structure in which the clip 7 is integrally provided on the bracket 4.
Is simple, and the shape of the mold for forming the bracket 4 is also simple. In particular, in the harness retaining structure of the present invention in this embodiment, since the convex portion for forming the press-fitting opening 42 is not provided on the mirror housing 31 side, the structure of the mirror housing 31 and the shape of the molding die are reduced. It is no different from the conventional mirror housing 31.

In the harness stopper structure of the present invention in this embodiment, the tube 8 in the elastically deformed state elastically returns to the original state (cylindrical tube state) and elastically contacts the contact surface 80. The tube 8 and the harnesses 5 and 6 are fixed at the abutment surface 80, and the stability of the tube 8 and the harnesses 5 and 6 is further increased, so that disconnection and pinching can be reliably prevented.

In the above-described embodiment, the projection 41 for forming the press-fitting opening 42 is provided only on the bracket 4 side. However, the projection 41 may be provided on the mirror housing 31 side. It may be provided on both the bracket 31 and the bracket 4. In this case, a projection for forming the press-fitting opening 42 is provided in the mirror housing 31, but the structure of the mirror housing 31 and the shape of the molding die are not so complicated.

In the above-described embodiment, the projection 41 for forming the press-fitting opening 42 is provided at one place on the bracket 4. The number is not particularly limited.

Further, in the above embodiment, the door mirror has been described, but the harness stopper structure of the present invention can be applied to a fender mirror, a track mirror, and the like.

[0025]

As is apparent from the above description, the harness fixing structure of the rearview mirror for a vehicle according to the present invention is provided with a projection for forming a press-fitting opening on at least one of the opposing surfaces of the mirror housing and the bracket. Because it is provided with
The structure of the mirror housing and the shape of the molding die are not so complicated, the structure of the bracket is simplified, and the shape of the die for molding the bracket is also simplified.
