To surely perform the OFF operation even if the power supply voltage is fluctuated when an energization control circuit is formed of an emitter- follower circuit.

A mirror housing of a body 1 is turnably provided by an internal motor 2. A relay switch 7a, an energization control circuit 9, and a deenergization control circuit 11 are provided in an energizing passage of the motor 2 as a control part 6. The energization control circuit 9 is connected to a base through a capacitor 8 for a timer in the emitter-follower type to which an excitation coil 7b is connected as the emitter load of transistors 13, 14. The collector side is connected to the power source side through the relay switch 7a. When the transistors 13, 14 of the energization control circuit 9 are tuned on by an operation switch 3, the motor 2 is energized through the relay switch 7a. When the relay switch 7a is turned off by the deenergization control circuit 11, the collector is shut off in the transistors 13, 14 of the energization control circuit 9, and malfunction such that the relay switch 7a is again turned on even when the power supply voltage is fluctuated can be prevented.
