Abstract
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 ().
