Abstract
A multi-plate clutch system includes: a pressure plate which is biased by a clutch spring in a direction in which driving friction plates and driven friction plates are brought into pressure contact with each other; and at least one of assist device configured to increase a pressure contact force when torque is changed for acceleration and the slipper device configured to decrease the pressure contact force when the torque is changed for deceleration. A ring member whose inner peripheral surface is put in sliding contact with an outer peripheral surface of one cam plate out of paired cam plates, which are included in at least one of the assist device and the slipper device, is fixed to a clutch inner, and oil discharging passages for guiding oil to a sliding contact portion between the one cam plate and the ring member are provided in outer peripheral edge portions of concave cams formed in the one cam plate. Accordingly, it is possible to supply a sufficient amount of oil to a sliding contact portion between the clutch inner and the outer periphery of the cam plate in a state where the clutch inner is centered together with the cam plate by being supported in sliding contact with the outer periphery of the cam plate.
