An armature is magnetically attracted to and is coupled with a rotor against an urging force of a resilient member by a magnetic attractive force of the rotor when a permanent magnet is placed into a first position. When the armature is coupled with the rotor, a rotational drive force of an internal combustion engine transmitted to the rotor is transmitted to a refrigerant compressor connected to the armature to rotate the refrigerant compressor. The armature is urged away from and is decoupled from the rotor by the urging force of the resilient member when the permanent magnet is placed into a second position. |
