    摘要： 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 being operable to hold a plurality of output-side rotating plates and to be rotationally driven together with the output shaft, the input-side rotating plates and the output-side rotating plates being alternately arranged; a pressure plate movable toward or away from the clutch center and rotatable relative to the clutch center to press the input-side rotating plates and the output-side rotating plates; and a stopper plate operable to contact the pressure plate and to suppress separation of the pressure plate from the clutch center by a predetermined distance or more; wherein the pressure plate includes a plurality of pressure-side fitting teeth holding at least one of the output-side rotating plates and arranged in circumferential directions; 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; and 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; and in a state where the pressure plate is in contact with the stopper plate, a portion of one of the center-side fitting teeth overlap with a portion of one of the pressure-side fitting teeth when seen in radial directions of the output shaft.

    摘要： A clutch device includes a pressure plate (70) movable toward or away from a clutch center (40) and rotatable relative to the clutch center to press input-side rotating plates (20) and output-side rotating plates (21). The clutch center includes center-side cam portions(60) each including a center-side assist cam surface (60A). At least one of the center-side cam portions includes at least one of a first center-side recess (62) recessed in a first direction from a surface of center-side cam portion at a side of a second direction or a second center-side recess recessed (64) in the second direction from a surface of the center-side cam portion at a side of the first direction.

    摘要： Pressure-side cam portions (90) of a pressure plate each include a pressure-side assist cam portion (91) including a pressure-side assist cam surface, a pressure-side body located between the pressure-side assist cam portion (91) and a pressure-side slipper cam portion (92), and a stepped portion (95, 96) between a main outer circumferential surface of the pressure-side body and a sub outer circumferential surface of the pressure-side assist cam portion. The outer circumferential surface is located radially inward of the pressure-side slipper cam portion. Two of the plurality of pressure-side cam portions, a circumferential direction from one pressure-side cam portion toward the other pressure-side cam portion is defined as a first circumferential direction and a circumferential direction from the other pressure-side cam portion toward the one pressure-side cam portion is defined as a second circumferential direction, the pressure plate is rotatable in the first circumferential direction from the pressure-side slipper cam surface toward the pressure-side assist cam surface of each of the pressure-side cam portions; and as seen in the axial direction of the output shaft, the stepped portion is adjacent to a radially innermost portion of an edge, on the side of the first circumferential direction, of the pressure-side cam hole.
