PURPOSE: To prevent a door mirror from over looking housing by rotating the door mirror to a housing position when the operation of a door lock switch means is detected when or after an ignition switch is turned off.

CONSTITUTION: When an ignition switch SW1 is turned off with a door mirror at a return position (working position), one input of an AND circuit 13 is started up from L to H. The output of a FF11 is L, and the other input of the AND circuit 13 is H, therefore, the output of the AND circuit is changed from L to H to trigger a one-shot circuit 16. A timer 1 is started with the output of the one-shot circuit 16 to generate an L signal for a certain period, and to send out the L signal from NOR circuits 2a, 2b. These signals turn on transistors Q3, Q4, energize a relay RL2 to turn off a contact point SW7 and turn on a contact point SW6, and rotate the door mirror to the housing position by a motor.
