PROBLEM TO BE SOLVED: To provide a geared motor capable of clearing instantaneous stopping by a magnetic induced clutch. SOLUTION: A lever 30 is rotated to a prescribed position, a laver 22 is rotated by a projection 22d which is engaged with a cam groove 16b, a pinion 20 is restrained by an inhibiting member 22e to inhibit the rotation of a sun gear 17d. A fan-shaped gear 28 receives the rotational torque of an induced ring 13 by means of the magnetic induction of a rotor 11 to inhibit the rotation of a lock gear 26 by a projection 28a. As far as the rotor 11 rotates, a planetary gear 17c is sandwiched by the sun gear 17d of which the rotation is inhibited and a ring gear 17f, so that it cannot rotate nor revolute to keep the lever 30 in a load condition. The rotation of the lock gear 26 is frictionally controlled to delay a prompt movement for extinguishing the magnetic induction by the instantaneous stopping, and to keep the load condition of the lever 30.
