Federnder Ring für Freiaufkopplung und Anlasser mit solchem Ring

摘要

In a one-way clutch used in a starter for engines, a locking concave (53) for locking a roller (51) thereto is formed on a roller-moving surface of one clutch member (23, 631, 34) having a peripheral surface facing a peripheral surface of the other clutch member (342, 641, 43) having a wedge-shaped groove (50) for accommodating the roller. A resilient member (55) for disengaging the roller from the locking concave at the time of overrunning is accommodated in an annular groove (54), thus urging the roller radially outwardly. The roller is prevented from colliding with the locking concave at the time of overrunning so that vibrations and noise are not generated.
