摘要： Provided is a power transmission device that can improve responsiveness when engaging a clutch and improve operability by reducing the sliding resistance of a receiving member. The power transmission device includes: a pressure member 5 that is capable pressing drive-side clutch plates and driven-side clutch plates against each other or releasing a press-contact force; a clutch spring 10 that urges the pressure member in a direction such that the clutch plates are pressed against each other; a receiving member 11 that is constituted by a separate member attached to the pressure member 5; and a back-torque limiting cam that reduces the press-contact force between the clutch plates when the rotation speed of an output member exceeds the rotation speed of an input member. The power transmission device includes a radially-outside restricting portion that is capable of restricting radially-outward movement of the receiving member 11 relative to the pressure member 5 and is capable of maintaining a clearance t between a side surface 11d of the receiving member 11 and an inner peripheral wall 4e of a clutch member 4.

摘要： The present invention provides a power transmission apparatus that is able to have an increased clutch capacity while being prevented from increasing in size in an axial direction.
An auxiliary clutch plate 17 different in diameter from driving and driven clutch plates 6 and 7 is disposed in a clutch housing 2. When the driving and driven clutch plates 6 and 7 are pressed against each other, the auxiliary clutch plate 17 is pressed so as to enable transmission of a driving force of an engine E to a driving wheel T. When a pressing force exerted on the driving and driven clutch plates 6 and 7 is released, a pressing force exerted on the auxiliary clutch plate 17 is released so as to cut off transmission of the driving force of the engine E to the driving wheel T.
