Next, the operation of the embodiment of the present invention configured as described above will be described. First, when the switching knob 25 is not tilted, the wedge-shaped portion 34 of the pin 33 is strongly pressed against the notch portion 36 by the urging force of the spring 35. When the switching knob 25 is not tilted like this, the rubber switch
Since the bottomed projection 39 located above S5 and S6 is not pressed by the push pin 27, the contacts a and b are not electrically connected. Therefore, the rubber switches S5 and S6 are in the opened state.

Next, when the switching knob 25 is tilted to the R (right) side, the wedge-shaped portion 34 of the pin 33 is pulled out from the cutout portion 36 against the biasing force of the spring 35 by the operating force thereof. Then, since the wedge-shaped portion 34 is pressed against the peripheral portion of the cutout portion 36 by the biasing force of the spring 35, the tilted state of the switching knob 25 is maintained. By tilting the switching knob 25 to the R side, the push pin 27 is pushed by the leg portion 30.
Is pushed down. And the head 27 of the diaper pin 27
1 causes the bottomed projection 39 to be elastically deformed, and as a result, the metal piece 4
1 makes contacts a and b. This allows the rubber switch
S6 is closed. The closed state of the rubber switch S6 is detected by the controller 51, and the controller 51 recognizes that the switching knob 25 is tilted to the R side.
That is, the controller 51 recognizes that the mode for adjusting the angle of the door mirror (R) 53 is selected.
Hereinafter, when the operation plate 23 is selectively tilted in the four directions of up, down, left and right, the corresponding push pin responds to the tilting operation.
27 is pushed down, the headed portion 271 elastically deforms the bottomed projection 39, and the metal piece 41 is brought into contact with the contacts a and b. As a result, any one of the rubber switches S1 to S4 corresponding to the tilting direction of the operation plate 23 is closed. The closed state of the rubber switches S1 to S4 is detected by the controller 51, a motor (not shown) is driven, and the door mirror (R) 53 is rotationally controlled in the up, down, left, and right directions in conjunction with the operation of the operation plate 23.

Next, when the switching knob 25 is tilted to the L (left) side from the neutral position, the wedge-shaped portion 34 of the pin 33 is actuated by the spring 35.
It is pulled out of the notch 36 against the urging force of. Then, since the wedge-shaped portion 34 is pressed against the peripheral portion of the cutout portion 36 by the biasing force of the spring 35, the tilted state of the switching knob 25 is maintained. The tilting of the switching knob 25 to the L side pushes the push pin 27 downward by the leg portion 31. Then, the bottomed projection 39 is elastically deformed by the head 271 of the push pin 27,
As a result, the metal piece 41 contacts the contacts a and b. As a result, the rubber switch S6 is closed. The closed state of the rubber switch S5 is detected by the controller 51, and the controller 51 recognizes that the switching knob 25 is tilted to the L side. That is, the controller 51 recognizes that the mode for adjusting the angle of the rearview mirror (L) 54 is selected. Hereinafter, the operation of tilting the operation plate 23 in the vertical and horizontal directions to control the rotation of the door mirror (L) in the vertical and horizontal directions is the same as the above-described control of the door mirror (R).

Next, when adjusting the angle of the room mirror 52, the switching knob 25 is tilted to the ROOM side. By operating the switching knob 25, the wedge-shaped portion 34 of the pin 33 is pulled out from the cutout portion 36 against the biasing force of the spring 35. Since the wedge-shaped portion 34 is pressed against the peripheral portion of the cutout portion 36 by the biasing force of the spring 35,
The tilted state of the switching knob 25 toward the ROOM side is maintained. The push pin 27 is pushed down by the legs 30 and 31 by tilting the switching knob 25 toward the ROOM side. Then, the bottomed projection 39 is elastically deformed by the head 271 of the push pin 27, and as a result, the metal piece 41 is brought into contact with the contacts a and b. This allows
The rubber switches S5 and S6 are closed. The closed state of the rubber switches S5 and S6 is detected by the controller 51, and the controller 51 recognizes that the switching knob 25 is tilted to the ROOM side. That is, the room mirror 52
The controller 51 recognizes that the mode for adjusting the angle is selected. Hereinafter, when the operation plate 23 is selectively tilted in four directions of up, down, left and right, the corresponding push pin 27 is pushed down in response to the tilting operation, and the head 271 causes the bottomed projection 39 to move. Elastically deformed metal pieces 4
1 is brought into contact with contacts a and b. As a result, any one of the rubber switches S1 to S4 corresponding to the tilting direction of the operation plate 23 is closed. The closed state of the rubber switches S1 to S4 is detected by the controller 51, a motor (not shown) is driven, and the rearview mirror 52 is rotationally controlled in the vertical and horizontal directions in conjunction with the operation of the operation plate 23. , When the switching knob 25 is tilted to the R side, close the rubber switch S6 and set the switching knob 25 to L.
If tilted to the side, close the rubber switch S5,
When the switching knob 25 is tilted to the ROOM side, the rubber switches S5 and S6 are closed. And the controller
By detecting the states of these rubber switches S5 and S6, 51 recognizes which mirror adjustment mode is selected by the switching knob 25.

Further, since the rubber switches S5 and S6 are closed when the switching knob 25 is tilted to the ROOM side, the rubber switch S5 and the rubber switch that is closed when the switching knob 25 is tilted to the ROOM side are It does not have to be provided separately from S6.

Also, the direction in which the switching knob 25 is switched to the R or L side
Since the directions for switching to the ROOM side are different from each other, erroneous operation of the switching knob 25 can be prevented.

The configurations of the rubber switches S1 to S6 are not limited to those in the above embodiment, and switches using conductive rubber may be used.
