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 clutch center includes center-side fitting teeth holding the input-side rotating plates and the output-side rotating plates, 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 center-side fitting teeth in a second direction. The oil channel allows clutch oil flowing at least at an inner peripheral surface of the outer peripheral wall to be discharged to outside of the clutch center.
