ABSTRACT:
An overload release clutch including a driving clutch member and a driven clutch member, for transmitting a torque from the former to the latter and suspending the torque transmission in the event more than a predetermined load is applied to the driven clutch member, by automatically disconnecting the two clutch members. A plurality of torque transmitting balls, interposed between both clutch members and received in respective ball receiving openings formed in the opposing inside surfaces of the clutch members, are moved out of the openings upon application of an overload, along a plurality of ball guiding slots formed which are in either one of the clutch members, extending in a slightly vertical shape from one end thereof communicating with each of the opening to the other end thereof so that the distance thereof from the axis of the clutch members are gradually changed. On the other clutch member a rotatable member of annular shape is fittingly disposed in an annular groove formed therein at a radial position confronting the other end of the slot so that it is able to rotate under pressure integrally with the ball which has been moved thereon without sliding friction, while the driven clutch member is restricted from rotary movement upon application thereto of any excessive torque.
