Abstract
An overrunning clutch comprising a ratchet wheel (1) and a plurality of pawls (2) is disclosed. Each of the pawls (2) is rotationally supported on a disk member (5) by a shaft (3). The clutch is characterized by a permanent magnet (4) being fixed on the disk member (5) between the axes of the disk member (5) and the shaft (3) and facing the tail end of each pawl (2). Because each of the pawls are not driven by a spring in the clutch, the clutch could not be malfunction due to the fatigue failure of the spring in the case of frequent heavy load.
