Abstract: A power transmission apparatus includes a clutch connected to an output shaft to rotate a wheel of a vehicle, and a clutch pressure plate movable between an operating position where driving and driven clutch plates are pressed against each other so as to enable transmission of a driving force of an engine to the wheel and a non-operating position where a pressing force exerted on the driving and driven clutch plates is released so as to cut off transmission of the driving force of the engine to the wheel. One of the driven clutch plates is attached to a second clutch, and another is attached to the clutch pressure plate. The clutch pressure plate includes an oil flow passage through which oil flows to the driven clutch plate attached to the clutch pressure plate.

Abstract: During movement of a mass of a centrifugal clutch a radially inner position to a radially outer position and a resulting increase in torque transmitted from an input gear to an output shaft, a power transmission apparatus includes a first torque region where the apparatus restricts operation of a pressing assist cam and a second torque region where the apparatus allows operation of the pressing assist cam.

Abstract: A transmission device has a clutch spring (8). The clutch spring (8) can generate rotational resistance that occurs when a pressure member (5) rotates relative to a clutch member (4) due to clearance between cam surfaces of a press-contact assisting cam or a back torque limiting cam. Thus, one end (8a) of the clutch spring (8) slides on a surface (10a) of a restricting member 10. A side surface (8b) of the clutch spring (8) is held in the longitudinal direction.
