Claim 4:
5. The clutch device according to claim 1, wherein
the pressure plate further includes:
a plurality of pressure-side cam portions provided in the body 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 such a direction from the pressure plate toward the clutch center to increase a pressing force between the input-side rotating plates and the output-side rotating plate when the pressure plate rotates with respect to the clutch center, and the pressure-side slipper cam surface being operable to separate the pressure plate from the clutch center to decrease the pressing force between the input-side rotating plates and the output-side rotating plates when the pressure plate rotates with respect to the clutch center; and
a body-side recessed portion recessed in the first direction from a second direction-side surface of the body; and

as seen in the axial direction of the output shaft, the body-side recessed portion at least partially overlaps one of the pressure-side cam portions.
