PURPOSE: To provide a selectively actuating device which can drive a plurality of objects to be driven without providing a plurality of driving sources and can reduce the size of a driving system. CONSTITUTION: A selectively actuating device is provided with a piece 17 which is generated based on the rotation of a driving motor 2, a rotating shaft 3A which rotatably supports the piece 17, and a piece 16 which is rotated by the rotational torque transmitted to the piece 16 when the piece 17 rotates in the direction b and provided with a cam section 16B. When the piece 17 rotates in the direction b, no rotational torque is transmitted to the piece 16, but the piece 16 is displaced along the rotating shaft 3A based on the sliding of a projection 16A formed on the piece 16 and a projection 17D formed on the inner periphery of the piece 17 in a step-like state.
