Is operated in the right direction, the first harness 47 on the right mirror side is operated.
Is connected to the negative electrode of the power supply 57, and the second harness 48 on the right mirror side is connected to the positive electrode of the power supply 57. Thereby, the second electrode 10 of the first motor 10 is
A current flows from the b side to the first electrode 10a side, and the first motor 1

3 harnesses 4 connecting 22 to a controller not shown
7 to 49 are provided in the actuator section 5, and one of the harnesses 47 to 49 is used as a common line connected to both the first and second motors 10 and 11, so that the number of harnesses is reduced. The wiring structure can be simplified with less.

The first and second motors 10
Since the connection position of the common line 47 with respect to the terminals 19 and 20 is arranged in the opposite direction between the right mirror and the left mirror, the symmetrically formed actuator section 5 is shared by the right mirror and the left mirror. Even when the first and second motors 10 and 11 are disposed at symmetric positions between the left and right mirrors, the mirror plate 7 is displaced left and right symmetrically, that is, in the opposite direction to the left and right in response to a switch operation in the same direction. Can be prevented.

That is, the left and right actuator units 5
By arranging the first to third harnesses 47 to 49 symmetrically, the current flow and the rotation direction of the first motor 10 are symmetrical between the left and right mirrors. The displacement direction is also symmetrical, and when the first operation switch 59 is operated in the same direction, the rotation direction of the mirror plate 7 is reversed left and right.

On the other hand, as described above, the common line 47
In the case where the connection positions of the left and right mirrors are arranged in the opposite directions so that the current flows in the opposite directions between the left and right mirrors, for example, by operating the first operation switch 59 to the right, the mirrors of the left and right mirrors Each of the plates 7 can be turned clockwise.

Therefore, means for setting the operation direction of the first operation switch 59 in the opposite direction between the left and right mirrors, changing the control signal output in response to the switch operation in the controller in the opposite direction, and the like are provided. Without taking any action, the left and right mirror plates 7 are rotated in the same direction in response to the same operation of the first operation switch 59 for controlling the flow of current from the harness common line 47 to the first motor dedicated harness 48. Can be done.

The first to fourth frames provided on the frame 4
Terminals 19 to 22 and first to third harnesses 47
4 harness holding grooves 52a
To 52d are formed in parallel, and the harness guide grooves 53 are formed in a direction orthogonal to the harness holding grooves 52a to 52d.
Formed, the above-mentioned harness holding grooves 52a to 52d
The leading end 47a of the common line formed of the first harness 47 installed at a specific portion of the common line is led out to the side through the harness guide groove 53, so that the leading end 47a of the common line
a can be easily installed in any of the harness holding grooves 52a to 52d.

In particular, when the groove depth of the harness guide groove 53 is set to be deeper than the groove depths of the harness holding grooves 52a to 52d as described above, the distal 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 and 49, a short circuit of the electric wire can be effectively prevented.

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.
Since the center of curvature O1 of the tilting support portion 37 is offset from the center of curvature O2 of the engagement portion 42 by a distance corresponding to the difference between the radii of curvature α and β of the two curved surfaces, the engagement The portion 42 can be brought into line contact with the tilt support portion 37 of the housing rear 9 at an appropriate position.

Therefore, it is possible to prevent the tilt change of the mirror mounting member 6 from becoming difficult due to the wedge effect caused by the shallow contact position between the tilt fulcrum 37 and the engaging portion 42. Insufficient support strength of the mirror mounting member 6 due to a deeper contact position between the tilting fulcrum 37 and the engaging portion 42 can be effectively prevented.

The engaging portion 42 of the mirror mounting member 6
Since the curvature difference between the curved surfaces constituting the tilt support portion 37 of the housing rear 9 is small, the lubrication of the grease filled between the two can be maintained in a good state. Moreover, as in the case where the radius of curvature α of the tilting fulcrum 37 and the radius of curvature 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 in an appropriate state due to a manufacturing error generated therebetween.

Further, the engaging portion 4 of the mirror mounting member 6
2 and the engaging member 44 are formed by curved surfaces having different curvatures, and the center of curvature O3 of the engaging member 44 is set with respect to the center of curvature O2 of the engaging portion 42 with respect to the curvature radii β and β ′ of the two curved surfaces. Are arranged at positions offset by a distance corresponding to the difference between the two, the engaging member 44 can be brought into line contact with the engaging portion 42 at an appropriate position.

In the above embodiment, the first to fourth terminals 1
The harnesses 47-4 are attached to the press-contact portions 19b-22b of 9-22.
Since the U-shaped groove 25 having a diameter corresponding to the diameter of the core wire of No. 9 is formed, the U-shaped groove 25 formed in the press-contact portions 19b to 22b is formed when the housing front 8 is attached to the frame 4. By externally fitting to the first to third harnesses 47 to 49 held at the joint portion 48 of the housing front 8, the covering 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 connected.

The operation of controlling the flow direction of the current from the common line of the harness to the harness dedicated to the first electric drive means without taking measures such as setting the control signal outputted in accordance with the reverse in the controller or the like. There is an advantage that the left and right mirror plates can be rotated in the same direction according to the operation of the switch in the same direction.

According to a second aspect of the present invention, in the connecting portion between the terminal and the harness, four harness holding grooves are formed in parallel, and a harness guide groove is formed in a direction orthogonal to the harness holding groove. Therefore, by leading the side of the harness, which constitutes the common line installed at a specific portion of each of the harness installation grooves, to the side through the harness guide groove, it is easy for any harness holding groove. There is an advantage that it can be installed.
