A vertical drive gear 17 screwed into the screw 16a of the operating rod 16 is rotatably installed in the case 15, and the operating rod 16 operates in accordance with the rotation of the drive gear 17 to adjust the vertical tilt angle of the mirror 5. I'm trying to adjust it. The vertical drive gear 17 meshes with a worm gear 19 fitted to the output shaft 6a of the motor 6 installed inside the visor 3 so as not to rotate together. A bevel gear 20 is fitted to the motor output shaft 6a so as to be slidable in the axial direction and rotate together, and a worm clutch 21 is integrated with the bevel gear 20.
is adapted to engage and disengage from a clutch portion 19a formed at the tip of the worm gear 19. The bevel gear 20 has a drive rod 23 fixed to the plunger 22 of the solenoid 8 installed inside the visor 3.
When the solenoid 8 is not energized, the bevel gear 20 is positioned at the position shown in FIG. 1, the clutches 21 and 19a are engaged, and the rotation of the motor output shaft 6a is transmitted to the worm gear 19. There is. Furthermore, when the solenoid 8 is energized and the plunger 22 is moved inward and the bevel gear 20 is moved, the clutches 21 and 19a are disengaged, and the bevel gear 24 is arranged at a position where it meshes with the moved bevel gear 20.
