To provide an inexpensive door mirror reverse interlocking system which prevents any positional deviation caused by the change of the voltage and the secular change, and is restored to the correctly set position, and is highly reliable in operation.

A reception side gear member 14a for reverse drive of an interlocking mechanism 14 is fixed to a middle portion of a rotary shaft 5b. The interlocking mechanism 14 has a wire member 15 which extends from a rotary shaft 2a of an electric-driven storage unit 4 so as to be rotated according to the turn during the development and storage of a door mirror body 13, and changes the angle of a mirror surface 3a downwardly and upwardly by the turn by transmitting via a reduction gear 18 the rotational force to the rotary shaft 5b which is a part of a mirror surface angle adjustment means of a mirror surface adjustment unit 5.
