Abstract
A unidirectional rotary clutch in a starter motor has a clutch inner interlocking with a motor, a clutch outer interlocking with a pinion gear and an elastic member-fitted clutch roller accommodated in a roller groove chamber. The clutch functions to propagate power driving forward rotation of the motor, but to cut off the propagation of power in the case of reverse rotation. The chamber is filled with grease mainly composed of hydrocarbon fats and oils to which 5.0 to 15.0% by weight of a fluorocarbon resinous agent is added.
