Abstract
A clutch device includes a clutch center, and a pressure plate movable toward or away from the clutch center, rotatable relative to the clutch center, and operable to press input-side rotating plates and output-side rotating plates. The pressure plate holds the output-side rotating plates and includes pressure-side fitting teeth projecting radially outward from an outer peripheral surface of an outer peripheral wall and arranged in circumferential directions, and an oil channel in an end portion of at least one of the pressure-side fitting teeth in a first direction. The oil channel allows clutch oil flowing at least at an inner peripheral surface of the outer peripheral wall to be discharged to the outside of the pressure plate.
