ABSTRACT:
An electromagnetically controlled spring clutch mechanism comprising a first boss member rotatable as a unit with an input rotating element, a second boss member rotatable as a unit with an output rotating element, a coil spring fitted over and across the first and second boss members, a rotation control member for hampering contraction of the coil spring, a movable member, a magnet for biasing the movable member magnetically toward the rotation control member, and an electromagnet for magnetically attracting the movable member away from the rotation control member. When the electromagnet is energized, the movable member moves away from the rotation control member to permit contraction of the coil spring member, and the contraction of the coil spring effects a driving connection between the first and second boss members.
