A door mirror control device supplies drive voltages to respective lock detection sections in left and right door mirrors. If motors are driven in accordance with the drive voltages, the door mirrors are operated from one of a retracted position or a deployed position toward the other of the retracted position or the deployed position, and the motors stop after the door mirrors reach either the retracted position or the deployed position. Operating time determination sections determine operating times of the door mirrors from changes in values of operating currents. Voltage setting sections change settings for the drive voltages supplied to lock detection circuits of the door mirrors based on the operating times of the left and right door mirrors such that the operating times of the left and right door mirrors match each other.
