ABSTRACT:
An electromagnetically controlled spring clutch mechanism including a rotating output member, a rotating input member, an armature assembly, an electromagnetic coil assembly and a coil spring. The coil spring is fitted astride both the output boss of the rotating output member and the input boss of the rotating input member. One end of the coil spring is anchored at the rotating input member, and the other is anchored to the armature assembly. The rotor of the rotating output member, the armature assembly, and the electromagnetic coil assembly are arranged in this sequence in the axial direction. The electromagnetic coil of the electromagnetic coil assembly is positioned radially outwardly of the coil spring. The electromagnetic coil assembly includes a casing, and this casing covers the rotor of the rotating output member, the armature assembly, the electromagnetic coil of the electromagnetic coil assembly and the coil spring.
