<p>A multi-plate clutch system includes at least one of an assist means and a slipper means. The assist means 24 assists the pressure plate 22 in increasing a pressure-contact force between driving friction plates 19 and driven friction plates 20 when torque for acceleration is changed, whereas the slipper means 25 decreases the pressure-contact force of the pressure plate 22 when torque for deceleration is changed. At least one of the assist means 24 and the slipper means 25 has paired cam plates 30, 50 which are opposed to each other in the axial direction. One cam plate 50 is inserted in a clutch inner 18A, and is engaged with the clutch inner 18A in such a way as to be non-rotatable relative to the clutch inner 18A. A stop ring 55 engaged with the one cam plate 50 is attached to the inner periphery of the clutch inner 18A in order to block the one cam plate 50 from moving relative to the clutch inner 18A in such an axial direction that the one cam plate 50 detaches from the other cam plate 30.</p> |
