摘要： A clutch device includes a clutch center and a pressure plate operable to move toward or away from the clutch center and rotatable relative to the clutch center. The pressure plate includes a pressure-side cam portion. The clutch center includes a center-side cam portion. The pressure plate includes a boss extending in movement directions. The clutch center includes a through hole in which a boss is insertable. The through hole extends along circumferential directions and allows movement of the boss along the circumferential directions and the movement directions. While a surface of the pressure-side cam portion and a surface of the center-side cam portion are in contact with each other, a distal end of the boss projects outward from the through hole.
