A power transmitting apparatus comprising: 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 means biases the pressure member in a direction so that the driving clutch plates and the driven clutch plate 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; 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 means on the pressure member side includes at least one receiving member characterised in that the receiving member is separate from the pressure member; a first cam surface is formed on the at least one receiving member. 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 means biases the pressure member in a direction so that the driving clutch plates and the driven clutch plate 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; 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 means on the pressure member side includes at least one receiving member characterised in that the receiving member is separate from the pressure member; a first cam surface is formed on the at least one receiving member.
