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 (4); an electromagnetic clutch including a rotor (5) for transmitting the magnetic flux of the solenoid (4); an armature (8) attracted onto the rotor (5) by the magnetic flux, and a return spring (13) urging the armature (8) in a direction away from the rotor (5) to create a clearance “t” therebetween. A boosting mechanism converts a torque of the input member (housing) (2) to an axial thrusting force when the armature of the electromagnetic clutch is attracted onto the rotor. A main clutch connects the input member (2) and the output member (shaft) (3) via the thrusting force generated by the boosting mechanism. This transmits the torque of the input member (2) to the output member (3).

Abstract: A plurality of inertial locking connectors wherein each inertial locking connector has a first housing having a locking part and a second housing having a locking arm with a locking projection. The locking projection has a contact surface formed on a front end of the locking projection with respect to a direction of mating and at an inclination with respect to the direction of mating. The contact surface engages the locking part when the first housing and the second housing are mated. Electrical contacts having a number of poles are accommodated in the first housing and the second housing. An angle of inclination is formed by a direction perpendicular to the mating direction and the contact surface. The angle of inclination decreases as the number of poles of the electrical contacts increases in each of the connectors.
