Particularly, when the groove depth of the harness guide groove 53 is set deeper than the groove depth of each of the harness holding grooves 52a to 52d as described above, the tip end portion 47a of the first harness 47 is set to another position. Since it can be led out to the side without interfering with the harnesses 48, 49, it is possible to effectively prevent short-circuiting of electric wires.

In the above embodiment, the engaging portion 42 of the mirror mounting member 6 and the tilt support portion 37 of the housing rear 9 are formed by curved surfaces having different curvatures, and
Since the center of curvature O1 of the tilt support portion 37 is arranged at a position offset from the center of curvature O2 of the engaging portion 42 by a distance corresponding to the difference between the curvature radii α and β of the curved surfaces, the engagement is performed. The portion 42 can be brought into line contact at an appropriate position of the tilt support portion 37 of the housing rear 9.

Therefore, it is possible to prevent the tilt change of the mirror mounting member 6 from becoming difficult due to the wedge effect resulting from the shallow contact position between the tilt fulcrum portion 37 and the engaging portion 42. It is possible to effectively prevent the supporting strength of the mirror mounting member 6 from being insufficient due to the deeper contact position between the tilt fulcrum portion 37 and the engaging portion 42.

The engaging portion 42 of the mirror mounting member 6 is also used.
Since the difference in curvature between the curved surfaces forming the tilting support portion 37 of the housing rear 9 is small, the lubricity of the grease filled between the two can be maintained in a good state. Moreover, as in the case where the curvature radius α of the tilt fulcrum portion 37 and the curvature radius β of the engaging portion 42 are set to be the same,
It is possible to prevent a situation in which the tilting fulcrum portion 37 and the engaging portion 42 cannot be brought into contact with each other in an appropriate state due to a manufacturing error that has occurred.

2 and the engaging member 44 are formed by curved surfaces having different curvatures, and the curvature center O3 of the engaging member 44 with respect to the curvature center O2 of the engaging portion 42 is the radius of curvature β, β'of both curved surfaces. Since it is arranged at a position offset by a distance corresponding to the difference of the above, the engaging member 44 can be brought into line contact at an appropriate position of the engaging portion 42.

In the above embodiment, the first to fourth terminals 1
Harnesses 47-4 are attached to the pressure contact portions 19b-22b of 9-22.
Since the U-shaped groove portion 25 having a diameter corresponding to the diameter of the core wire of 9 is formed, the U-shaped groove portion 25 formed in the pressure contact portions 19b to 22b is attached to the above-mentioned pressure contact portions 19b to 22b when the housing front 8 is attached to the frame 4. By externally fitting the first to third harnesses 47 to 49 held by the joint portion 48 of the housing front 8, the coating can be automatically broken. Therefore, the first to fourth terminals 19 to 2
2 and the first to third harnesses 47 to 49 can be easily electrically connected.
