Abstract: A power transmission device has an interlocking member 9 moving a pressure member 5 from an inactive position to an active position. A release spring (m) applies an urging force, while allowing movements of the interlocking member 9 and the pressure member 5, until drive-side clutch plates 6 and driven-side clutch plates 7 reach an engaged state before the drive-side clutch plates 6 and the driven-side clutch plates 7 are pressed against each other. A clutch spring 11 is compressed in a process where the interlocking member 9 moves after the drive-side clutch plates 6 and the driven-side clutch plates 7 have reached the engaged state. The clutch spring applying a press-contact force between the drive-side clutch plates 6 and the driven-side clutch plates 7 while allowing movements of the interlocking member 9 and the pressure member 5. The set load of the clutch spring 11 is set to be smaller than the maximum load of the release spring (m).

Abstract: A power transmission device has a clutch member, a pressure member 5, a weight member 8, an interlocking member 9 and a bearing holding member C coupled to an activation member 10. The bearing holder member C holds a bearing B1 interposed between the activation member 10 and the pressure member 5. The bearing holding member C has a cylindrical member with one open end. An open end portion Ca is fit into and attached to a recessed portion 4d formed in a first clutch member 4a.

Abstract: A power transmission device has a first clutch member 4a coupled to an output member 3. A second clutch member 4b has a plurality of driven-side clutch plates 7. A back-torque transmitting cam presses the drive-side clutch plates 6 and the driven-side clutch plates 7 against each other by moving the second clutch member 4b when a rotational force is input to the first clutch member 4a. A cushioning member 12 is interposed between the first clutch member 4a and the second clutch member 4b. The cushioning member 12, by being compressed, applies an urging force while allowing movements of an interlocking member 9 and a pressure member 5 in a process where the interlocking member 9 moves and the pressure member 5 moves from the inactive position toward the active position.

Abstract: A power transmission device includes an input rotary member having a pressing portion, and an output rotary member having a receiving portion to be pressed by the pressing portion. The input rotary member forces the output rotary member to rotate when resilient members disposed between the input rotary member and the output rotary member are deformed by predetermined amounts.
