Abstract

PURPOSE: To surely maintain an anti-reversal function for a long time, by setting prescribed friction coefficients between the contact surfaces of a stopper and a gear and between those of the stopper and a pole plate.
CONSTITUTION: A rotor 10 made of a permanent magnet is provided. A first output pinion 12 and an anti-reversal cam 11 are integrally provided on the top of the central part of the rotor. A stopper 22 having a projection 23, which is engaged with the cam 11, a first gear 24 engaged with the first output pinion 12, and a push spring 28 for thrusting the first gear 24 and the stopper 22 on a second pole plate 13 are mounted on a shaft 16 on the pole plate 13. A washer 40 or the like is interposed between the stopper 22 and the second pole plate 13 and the friction coefficient between the contact surfaces of the first gear 24 and the stopper 22 is made larger than that between those of the stopper 22 and the second pole plate 13 so that the stopper 22 swings following up the rotation of the first gear 24.
