摘要： 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 is extremely simplified.

摘要： An improved engine supporting structure for a motorcycle wherein a power unit is constructed integrally of an engine, a crankcase and a transmission case and is subjected to pivotal motions with respect to the frame together with a rear wheel. The engine is so arranged that its main axis of inertia is substanially horizontal, and the engine constituting a part of the power unit is pivotally connected to the lower end of a link which in turn has its upper end pivotally connected to the frame. The link is so arranged that its upper and lower pivots are substantially in a vertical line, and the rear portion of the power unit supporting the rear wheel is connected to the frame through a shock absorber. In this manner, the transmission of engine vibrations to the frame is restricted, the following characteristics of the rear wheel in the longitudinal direction are improved, and the riding quality is improved.
