PROBLEM TO BE SOLVED: To provide a vehicular mirror system capable of miniaturizing a motor. SOLUTION: An elastic force is individually applied to a clutch 50 and a stopper 60 by a first twisted coil spring 56 and a second twisted coil spring 62 which are mutually independent. The elastic displacement amounts of the first twisted coil spring 56 and the second twisted coil spring 62 can be respectively suppressed in a state where a stopper and a clutch are released. Moreover, the elastic force of the first twisted coil spring 56 acting on an engagement portion between the clutch 50 and a gear 42, and the elastic force of the second elastic member acting on the engagement portion between the stopper 60 and a case 28 can be decreased. Therefore, frictional resistance acting on between the clutch 50 and the gear 42, and the stopper 60 and the case 28 can be decreased, so that driving torque of a motor 36 for returning to an ordinary state can be set smaller, thereby achieving miniaturization of the motor 36.
