Abstract:
A power transmitting apparatus has a clutch member and a pressure member. The cam surfaces of the pressure-contact assist cam face each other. The cam surfaces of the back torque limiter cam face each other. A receiving portion for a clutch spring ( 10 ) on the pressure member ( 5 ) side has a receiving member ( 11 ) separate from the pressure member ( 5 ). A first cam surface (C 1 ) and a second cam surface (C 2 ), constituting the back torque limiter cam, are, respectively, formed on the receiving member ( 11 ) and the clutch member ( 4 ). A third cam surface (C 3 ) and a fourth cam surface (C 4 ), constituting the pressure-contact assist cam, are, respectively, formed on the pressure member ( 5 ) and the clutch member ( 4 ).

Claim (Index 1):
A power transmitting apparatus comprising:\n a clutch housing that rotates with the rotation of an input member, a plurality of driving clutch plates are attached to the clutch housing; a clutch member includes a plurality of driven clutch plates formed alternately between the driving clutch plates of the clutch housing, the clutch member is connected to an output member; a pressure member is attached to the clutch member, the pressure member brings the driving clutch plates and the driven clutch plates into a pressure contact or to a release pressure-contact force, axial movement occurs relative to the clutch member; a biasing mechanism biases the pressure member in a direction so that the driving clutch plates and the driven clutch plates come into pressure contact; a pressure-contact assist cam increases the pressure-contact force between the driving clutch plates and the driven clutch plates when rotational force input into the input member is transmitted to the output member and the pressure member and the clutch member rotate relative to each other; and a back torque limiter cam releases the pressure-contact force between the driving clutch plates and the driven clutch plates when rotation of the output member exceeds the rotational speed of the input member and the pressure member and the clutch member rotate relative to each other; the power transmitting apparatus transmitting or cutting off rotational force input into the input member to the output member by bringing the driving clutch plates and the driven clutch plates into pressure contact or releasing the pressure-contact force; a receiving portion for the biasing mechanism on the pressure member side includes at least one receiving member separate from the pressure member; a first cam surface and a second cam surface, constituting one of the pressure-contact assist cam and the back torque limiter cam, are, respectively, formed on the at least one receiving member and the clutch member; and a third cam surface and a fourth cam surface, constituting the other of the pressure-contact assist cam and the back torque limiter cam, are, respectively, formed on the pressure member and the clutch member.
