A pair of drive gears rotated by a drive motor is meshed with meshing surfaces of a pair of slide guides of a light shield body. A plurality of rotation rollers rotate on roll surfaces of the slide guides and hold the pair of slide guides in a thicknesswise direction of the light shield body. The drive gears have contact portions that come into contact with side surfaces of the slide guides that are arranged to face each other or face opposite directions. Accordingly, a vehicle sun visor apparatus may be reduced in size. |
