PROBLEM TO BE SOLVED: To fix a cam plate to a clutch inner not to be deviated in a circumferential direction, without increase in the number of parts and increase in weight and cost, in a multi-plate clutch device including at least one of: an assist means enhancing a pressure-contact force of driving friction plates and driven friction plates by a pressure plate, in torque fluctuation on an acceleration side; and a slipper means reducing the pressure-contact force in torque fluctuation on a deceleration side. SOLUTION: At least one of the assist means 24 and the slipper means 25 has a pair of cam plates 30, 50 opposed to each other in an axial direction. One cam plate 50 is inserted into and engaged with the clutch inner 18A not to be relatively rotated. A snap ring 55 engaged with one cam plate 50 is installed to an inner periphery of the clutch inner 18A to prevent relative movement in the axial direction with respect to the clutch inner 18A of one cam plate 50 on a side detached from the other cam plate 30.
