It also possesses and a second motor 3B, a second worm wheel 4B, and a second rod 5B as the second angle-adjusting mechanism. The first motor 3A and the second motor 3B have the same shape. The first motor 3A is accommodated within an actuator housing 2 at a front side. The second motor 3B is accommodated within an actuator housing 2 at a rear side. These motors 3A and 3B are placed so that they are overlapped with each other when viewed in a direction perpendicular to the mirror surface.
