[Scope of utility model registration request] Left and right drive motors for rotating the left and right side mirrors of an automobile toward a first position by forward rotation and toward a second position by reverse rotation; and when the left and right side mirrors are respectively at the first position. left and right side first position detection switches that are turned off only when the left and right side mirrors are respectively in the second position; and left and right side second position detection switches that are turned off only when the left and right side mirrors are respectively in the second position, and an on command signal that is turned on only when externally operated. a momentary type operating switch that outputs , and first and second relays each having a normally open contact that is turned on in an operating state in response to energization, and a normally closed contact that is turned on in an inoperable state in response to power interruption. and a first switching element that is turned on when the ON command signal is output with at least one of the left and right first position detection switches being turned on and forms a current conduction path for the first relay. , a second switching element that is turned on when the on-command signal is output with the left and right first position detection switches both turned off, and forms a current conduction path for the second relay; third and fourth switching elements that are turned on through the left and right side first position detection switches that are in the on state when the first relay is operated; a first holding circuit that maintains the first switching element in the on state while at least one of the switching elements is in the on state; and the left and right second positions that are in the on state when the second relay is operated. The fifth and sixth switching elements are turned on through the respective detection switches, and the second switching element is maintained in the on state during a period in which at least one of the fifth and sixth switching elements is in the on state. a second holding circuit, and when the first relay is operated, the energizing path for forward rotation of the left drive motor is connected to the normally open contact of the first relay and the normally closed contact of the second relay. A normally-open contact of the first relay, a normally-closed contact of the second relay, and the fourth switching element are formed through the contact and the third switching element, and the current-carrying path for forward rotation of the right drive motor connects the normally-open contact of the first relay, the normally-closed contact of the second relay, and the fourth switching element. In addition, when the second relay is operated, the energizing path for reverse rotation of the left drive motor connects the normally open contact of the second relay and the normally open contact of the first relay. A normally-open contact of the second relay, a normally-closed contact of the first relay, and the sixth switching element are formed through the closed contact and the fifth switching element, and the energization path for reverse rotation of the right drive motor is formed through the normally-open contact of the second relay, the normally-closed contact of the first relay, and the sixth switching element.
