Claim 2:
3. The clutch device according to claim 1, wherein the pressure plate includes:
a plurality of pressure-side cam portions located radially inward of the outer peripheral wall and each including at least one of a pressure-side assist cam surface and a pressure-side slipper cam surface, the pressure-side assist cam surface being operable to generate a force in the direction from the pressure plate toward the clutch center in order to increase a pressing force between the input-side rotating plates and the output-side rotating plates upon rotation relative to the clutch center, the pressure-side slipper cam surface being operable to cause the pressure plate to move away from the clutch center in order to reduce the pressing force between the input-side rotating plates and the output-side rotating plates upon rotation relative to the clutch center; and
the oil channel is located radially outward of one of the pressure-side cam portions.
