Abstract

A clutch for equipment which is powered by an internal combustion engine, comprising a drive member which is connected to an output shaft of the engine, a driven member connected to an input shaft of a power transmission device, a number of clutch plates which are interposed between the drive member and the driven member for frictional engagement between the two members by a pressure member which is axially moveable and is biased by a spring, a lifter member for disengagement of the two members against the biasing force acting on the pressure member, and a brake device for stopping the motion of the driven member when the power transmission between the two members is disconnected. The brake device comprises a friction plate which is provided coaxially to the input shaft of the transmission device so as to be moveable along the axial direction but fixed along the circumferential direction and a brake plate which can press the friction plate against an axial end surface of the driven member in cooperation with the axial motion of the pressure member. Since the braking action of the brake device is produced by the axial motion of the lifter member, the structure for the brake device i…
