A clutch device to allow or interrupt transfer of a rotation driving force of an input shaft to an output shaft, the clutch device comprising: a clutch center housed in a clutch housing holding a plurality of input-side rotating plates to be rotationally driven by rotational driving of the input shaft, the clutch center holding a plurality of output-side rotating plates and being operable to be rotationally driven together with the output shaft, the input-side rotating plates and the output-side rotating plates being alternately arranged; and a pressure plate movable toward or away from the clutch center and rotatable relative to the clutch center, the pressure plate being operable to press the input-side rotating plates and the output-side rotating plates; wherein the clutch center includes: an output shaft holding portion to which the output shaft is coupled; an outer peripheral wall located radially outward of the output shaft holding portion; a plurality of center-side fitting teeth holding the output-side rotating plates, projecting radially outward from an outer peripheral surface of the outer peripheral wall, and arranged in circumferential directions; characterized in that the clutch center further includes an oil channel located in an end portion of at least one of the center-side fitting teeth in a second direction, a direction in which the pressure plate moves toward the clutch center being a first direction, a direction in which the pressure plate moves away from the clutch center being the second direction; wherein 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. a clutch center housed in a clutch housing holding a plurality of input-side rotating plates to be rotationally driven by rotational driving of the input shaft, the clutch center holding a plurality of output-side rotating plates and being operable to be rotationally driven together with the output shaft, the input-side rotating plates and the output-side rotating plates being alternately arranged; and a pressure plate movable toward or away from the clutch center and rotatable relative to the clutch center, the pressure plate being operable to press the input-side rotating plates and the output-side rotating plates; wherein the clutch center includes: an output shaft holding portion to which the output shaft is coupled; an outer peripheral wall located radially outward of the output shaft holding portion; a plurality of center-side fitting teeth holding the output-side rotating plates, projecting radially outward from an outer peripheral surface of the outer peripheral wall, and arranged in circumferential directions; characterized in that the clutch center further includes an oil channel located in an end portion of at least one of the center-side fitting teeth in a second direction, a direction in which the pressure plate moves toward the clutch center being a first direction, a direction in which the pressure plate moves away from the clutch center being the second direction; wherein 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. an output shaft holding portion to which the output shaft is coupled; an outer peripheral wall located radially outward of the output shaft holding portion; a plurality of center-side fitting teeth holding the output-side rotating plates, projecting radially outward from an outer peripheral surface of the outer peripheral wall, and arranged in circumferential directions; characterized in that the clutch center further includes an oil channel located in an end portion of at least one of the center-side fitting teeth in a second direction, a direction in which the pressure plate moves toward the clutch center being a first direction, a direction in which the pressure plate moves away from the clutch center being the second direction; wherein 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.
