A clutch (3) having: a clutch housing (32) wherein drive plates (33) are provided so as to be capable of moving in the axial direction; a clutch hub (34) that transmits rotational power to an output shaft; a clutch sleeve (35) wherein driven plates (36) are provided so as to be capable of moving in the axial direction; and a pressure disk (40) that biases the drive plates (33) and the driven plates (36) toward the clutch hub (34) side. This clutch also has a back torque limiter (7), which moves the pressure disk (40) in the direction away from the clutch hub (34) when back torque is applied. The clutch hub (34) is provided with a limiting means that limits the movement of the pressure disk (40) in the direction away from the clutch hub (34) when the rotational frequency of the output shaft is less than a prescribed value. |
