ABSTRACT:
An electromagnetically controlled spring clutch mechanism includes a rotating output member, a rotating input member, a coil spring fitted astride the outer peripheral portions of these two members, an armature assembly disposed on the outer peripheral portion of the coil spring, and an electromagnetic coil assembly. When the electromagnetic coil is deenergized, the coil spring contracts in a tightening direction so that the output and input members are drivingly coupled together. When the electromagnetic coil is energized, rotation of the armature assembly is hampered, and the coil spring expands so that the output and input members are decoupled.
