In a first hydraulic clutch deviceprovided with a first clutch inner, a pressure bearing plate portionD disposed on the first clutch inneropposing driving and driven friction platesand, a clutch pistonthat is consecutively disposed to a pressurizing plate portionD and moves to the side to pressurize the driving and driven friction platesandin accordance with an increase in a hydraulic pressure in a control hydraulic chamber, a piston guidethat forms a control hydraulic chamberbetween itself and the clutch piston, and a canceller platethat forms a hydraulic canceller chamberon the side opposite to the control hydraulic pressure chamber, a projection portionof the canceller plateand a notch portiondisposed in the piston guideand engaged with the projection portionare engaged with each other and assembled, and a clipthat is engaged with an engagement grooveof the notch portionand regulates axial movement of the canceller plateis disposed.

Hydraulic clutch device

A power transmission apparatus with a reaction force converted by a boosting mechanism used as a fastening force for an electromagnetic clutch has a solenoid (); an electromagnetic clutch including a rotor () for transmitting the magnetic flux of the solenoid (); an armature () attracted onto the rotor () by the magnetic flux, and a return spring () urging the armature () in a direction away from the rotor () to create a clearance 't' therebetween. A boosting mechanism converts a torque of the input member (housing) () to an axial thrusting force when the armature of the electromagnetic clutch is attracted onto the rotor. A main clutch connects the input member () and the output member (shaft) () via the thrusting force generated by the boosting mechanism. This transmits the torque of the input member () to the output member ().
