A clutch apparatus has a counter torque reduction mechanism, whose action is prevented by a cancel mechanism when the rotational speed of the clutch hub is equal to or lower than a predetermined rotational speed. The cancel mechanism 76 includes a weight member 77 fitted for radial sliding movement in a clutch hub 46 having an engaging portion 81 at a radially inner end portion thereof, an elastic member 78 which biases the weight member 77 radially inwardly, and a locking element 82 formed on the output power shaft 20 or on a locking member 49 fixed to the output power shaft 20, in such a manner as to be capable of being engaged with the engaging portion 81 from the side opposite to a pressure plate 45. |
