PROBLEM TO BE SOLVED: To provide a clutch equipped with a back-torque limiter, simple in structure and easy to manufacture.SOLUTION: A clutch 3 comprises: a clutch housing 32 in which drive plates 33 are provided to be movable in an axial direction; a clutch hub 34 transmitting rotational power to an output shaft; a clutch sleeve 35 in which driven plates 36 are provided to be movable in the axial direction; and a pressure disc 40 urging the drive plates 33 and the driven plates 36 toward the clutch hub 34. The clutch 3 further comprises: a back-torque limiter 7 moving the pressure disc 40 in a direction away from the clutch hub 34 if back-torque is applied; and restriction means restricting the movement of the pressure disc 40 in the direction away from the clutch hub 34 if rotation speed of the output shaft is lower than a predetermined value, the restriction means being provided in the clutch hub 34. |
