ABSTRACT:
An overrunning clutch has a drive shaft, a driven shaft coaxial with the drive shaft and a cylindrical body secured to and coaxial with the driven shaft. The cylindrical body is arranged to surround a transmission section of the drive shaft and includes a plurality of cam surfaces formed in its inner peripheral surface. The cylindrical body acts as an overrunning clutch. Recesses are radially formed in the corresponding cam surfaces and adapted to hold rollers against the action of spring. A retainer is held within the cylindrical body and includes a plurality of roller pockets corresponding to the cam surfaces, a plurality of rollers rollingly disposed within the roller pockets and contactable with the inner peripheral surface of the cylindrical body and the peripheral surface of the transmission section of the drive shaft, and springs disposed within the roller pockets and adapted to urge the rollers in the direction in which the rollers are locked in the cam surfaces. The overrunning clutch is designed to firmly hold the rollers in such a position that they can race and to eliminate "dancing phenomenon" of the rollers.
