Thereby, the mirror body 46 (mirror 48 and mirror holder 50) is tilted in at least one of the vertical direction and the vehicle width direction by the rod drive 32, and the mirror surface 48A angle of the mirror 48 (viewing direction of the occupant supported by the mirror 48). Is adjusted automatically (electrically) in at least one of the vertical direction and the vehicle width direction.

Further, when a predetermined tilting force is manually applied to the mirror body 46, the rod drive 32 receives a load in the axial direction (vehicle longitudinal direction), and the tip of the claw portion 38A of the engagement claw 38 is a rod. By receiving a load in the vehicle longitudinal direction from the drive 32, the connecting portion 42 of the meshing claw 38 is elastically deformed (twisted), and the claw portion 38A is rotated about the connecting portion 42 as a rotation center. For this reason, the rod drive 32 is moved in the axial direction (vehicle longitudinal direction) when the claw portion 38A gets over the thread of the screw 44 of the rod drive 32. Thereby, the mirror body 46 is tilted, and the mirror surface 48A angle of the mirror 48 is manually adjusted.

Here, the connecting portion 42 is disposed substantially perpendicular to the vehicle front-rear direction (the axial direction of the cylindrical portion 34). Thereby, the load for rotating the claw portion 38A to the vehicle front side with the connection portion 42 as the rotation center, and the load for rotating the claw portion 38A to the vehicle rear side with the connection portion 42 as the rotation center.

Further, in the wheel drive 30, the meshing claws 38 are formed in a substantially flat plate shape and are disposed substantially perpendicular to the axial direction of the cylindrical body portion 34. For this reason, the dimension of the axial direction of the wheel drive 30 can be shortened (it can be made compact) compared with the case where the meshing claw 38 is extended in the vehicle front-rear direction. Thereby, the meshing position of the meshing claw 38 (claw part 38A) with the rod drive 32 (screw groove of the screw 44) can be brought closer to the cylindrical body part 34 side, and the dimension in the vehicle front-rear direction of the mirror surface adjustment mechanism 26 is achieved. Can be reduced.
