ABSTRACT:
An overrunning clutch comprising a clutch inner member, a cylindrical member provides at the outer side of the clutch inner member, a clutch outer member provided at the outer side of the cylindrical member, and two circumferential rows of rollers movably disposed between the clutch inner member and the cylindrical member and between the cylindrical member and the clutch outer member. The upper limit value of torque transmitted between the clutch outer member and the cylindrical member through the outer circumferential row of rollers is set so as to be greater than the upper limit value of torque transmitted between the cylindrical member and the clutch inner member through the inner circumferential row of rollers. It is therefore possible to increase the amount of energy absorbed without lowering the upper limit value of transmitted torque. Thus, it is possible to prevent damage to the constituent elements and a consequent lowering of the function of the overrunning clutch.
