Abstract: A power transmission device has a back torque transmission cam that brings driving clutch plates 6 and driven clutch plates 7 into press contact with each other. A second clutch member 4b is moved when a rotational force is input to a first clutch member 4a via the output shaft 3. The pressure member 5 is located at a non-actuation position. A torque transmission portion transmits a rotational force transmitted to the second clutch member 4b to the first clutch member 4a not via the back torque transmission cam.

Abstract: A belt-type continuously variable transmission capable of continuously changing a speed reduction ratio of a driven pulley to a drive pulley, has a speed reduction ratio regulation mechanism that regulates a minimum speed reduction ratio of the driven pulley to the drive pulley. The driven pulley includes a fixed sheave, a movable sheave displaceable in an axial direction with respect to the fixed sheave, and a coil spring that urges the movable sheave toward the fixed sheave. The speed reduction ratio regulation mechanism has a swing arm that adjusts an allowable range in which moving away in an axial direction of the movable sheave with respect to the fixed sheave is possible, and a regulation drive section that drives the swing distal end portion of the swing arm to swing continuously.

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 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: Provided is a centrifugal clutch configured so that a clutch weight can be smoothly displaced without interference with backward displacement of the clutch weight in a rotary drive direction of a drive plate and assist thrust can be stably generated. A centrifugal clutch 200 includes, through swing support pins 214, clutch weights 230 on a drive plate 210 to be rotatably driven by drive force of an engine, and includes plate-side cam bodies 218 and dampers 221. The clutch weight 230 turnably displaces to a clutch outer 240 side through the swing support pin 214, and includes a weight-side cam body 235 configured to climb on the plate-side cam body 218 and a damper groove 236. The damper groove 236 is formed such that a groove width W2 for fitting the damper 221 when the clutch weight 230 is at a clutch-ON position is wider to a front side in a rotary drive direction of the drive plate 210 than a groove width W1 for fitting the damper 221 when the clutch weight 230 is at a clutch-OFF position.

Abstract: Provided is a centrifugal clutch configured so that tilt of a clutch weight can be more effectively reduced to reduce occurrence of uneven wear of the clutch weight and a clutch shoe and smoothly swing the clutch weight. A centrifugal clutch 200 includes clutch weights 230 and plate-side cam bodies 218 on a drive plate 210 to be rotatably driven by drive force of an engine. The clutch weight 230 turnably displaces to a clutch outer 240 side, and includes a weight-side cam body 238 configured to climb on the plate-side cam body 218. In the clutch weight 230, each of a center portion CCP in a cam contact area CE between the plate-side cam body 218 and the weight-side cam body 238, the positions FP1, FP2 of action of force F1, F2 of a coupling spring 235, and a center portion SCP of a clutch shoe 236 in a thickness direction thereof is coincident with a barycentric position WCP of the clutch weight 230.
