■ Locking hole 58 of the protrusion 57 at the tip of the stationary pivot 53
By hooking a tool to and pulling the tool, the stationary pivot 53 is pulled out against the spring 61, and the engagement piece 56 of the stationary pivot 53 is pulled out from the engagement groove 12.
The stationary pivot 53 is rotated approximately 90 degrees to release the tool tension, and the force of the spring 61 places the end surface of the engaging piece 56 on the end surface of the columnar body 11. In this state, the spherical fulcrum portion 54 of the stationary pivot 53 protrudes outward from within the spacer fitting portion 50, and the space between the spacer fitting portion 50 and the spherical fulcrum portion 54 becomes large.

A spacer 59 having a half-split structure is provided in the spacer fitting portion 50.
are inserted and fitted using the space.

After that, the stationary pivot 53 is rotated 90 degrees and the engaging piece 5
By aligning the engagement piece 6 with the engagement groove 12 of the column body 11, the engagement piece 56 is engaged with the engagement groove 12 by the elastic force of the spring 61.

For this purpose, the spherical fulcrum portion 54 of the stationary pivot 53 fits into the spherical receiving portion 60 of the spacer 59.

Next, the operation will be explained.

(1) Tilt the mirror around the Y-axis In the tilting mechanism B around the Y-axis, the motor 74 is rotationally driven to rotate the worm 76 and the worm wheel 76a.

Gear 62 is rotated via intermediate gear 75. This gear 6
2 rotates the movable pivot 63 via the sliding groove 65 and the guide portion 69. A spring clip 73 is screwed onto the male threaded portion 67 of this movable pivot 63, and as described above, since this spring clip 73 is engaged with the front case 8 side, the spring clip 73 is attached to the female threaded member (
Due to its rotation, the movable pivot 63 moves upward in FIG. 2.

This movement of the movable pivot 63 pushes the mirror board 45 forward via the ball joint part 71, and the mirror board 45 is rotated about the vertical axis Y using the spherical fulcrum part 54 of the stationary pivot 53 of the tilting fulcrum mechanism A as a fulcrum. The mirror 47 is tilted to the center, and the mirror 47 is tilted in the direction around the Y axis together with the mirror substrate 45. This tilting is possible until the mirror substrate 45 comes into contact with one of the stoppers 35.

When the mirror substrate 45 is tilted, the movable pivot 63 swings toward the stationary pivot 53 using the guide portion 69 inserted into the sliding groove 65 as a fulcrum, and the boot 72 is moved toward the movable pivot 6
3 extends upward in FIG. 2.

When the mirror substrate 45 is tilted, the spherical convex portion 46 provided on the mirror substrate 45 slides against the spherical seat portion 51, and the spacer 59 slides against the spherical fulcrum portion 54 of the stationary pivot 53.
At this time, the guide groove 48 of the spherical convex portion 46 slides against the protrusion 22,22 provided on the spherical seat portion 51.
48 slides, and these perform a guide function to restrict movement of the mirror 47 (mirror substrate 45) in directions other than the Y# rotation direction.

Further, the mirror 47 is tilted in the opposite direction by rotating the motor 74 in the opposite direction to move the movable pivot 63 downward in FIG.

(2) Tilting of the X-axis roll of the mirror In the tilting mechanism C around the X-axis, the motor 74 is rotationally driven to rotate the gear 62 via the reduction gear mechanism 77. The rotation of the gear 62 rotates the movable pivot 63 via the sliding groove 65 and the guide portion 69.

The action of the internally threaded member of the spring clip 73 moves the movable pivot 63 upward in FIG. Due to this movement of the movable pivot 63, the mirror substrate 45 tilts around the horizontal axis X using the spherical fulcrum portion 54 of the stationary pivot 53 as a fulcrum,
Therefore, the mirror 47 tilts together with the mirror substrate 45 in the direction around the X axis.

This tilting is possible until the mirror substrate 45 comes into contact with the other stopper 34.

When the mirror substrate 45 is tilted, the spherical convex portion 46 provided on the mirror substrate 45 slides against the spherical seat portion 51, and the spacer 59 slides against the spherical fulcrum portion 54 of the stationary pivot 53. However, the protrusions 22.22 are located on the horizontal axis X, and since the protrusions 22.22 are cylindrical, these protrusions 22.22 rotate relative to each other within the guide grooves 48.48. These protrusions 22, 22 and guide grooves 48, 48 perform a guide function to restrict movement of the mirror 47 in directions other than around the X-axis.

Further, the mirror 47 is tilted in the opposite direction by rotating the motor 74 in the opposite direction to move the movable pivot 63 downward in FIG.
