ABSTRACT:
An electromagnetic spring-wound clutch includes a first rotary member formed of a hub having an annular flange and a tubular portion integrally combined with the hub and adapted for direct coupling to a rotary shaft of an apparatus for use with the clutch. The tubular portion of the first rotary member is concentrically and rotatably fitted through a stationary annular field core which accommodates an electromagnetic coil and is arranged in facing relation with the annular flange of the hub. A non-magnetic annular member is rigidly fitted on the hub, and an armature is rotatably fitted on the hub and interposed between the annular flange and the annular member. A coil spring is wound around the annular member and a second rotary member rotatably fitted on the tubular portion of the first rotary member, for gripping engagement therewith. A covering member is disposed over the second rotary member, the coil spring and the armature member and secured to the second rotary member in a manner permitting adjustment of its circumferential position. The covering member has its peripheral wall formed with an opening which is engaged by a radial protuberance formed on the armature member and has a larger circumferential size than that of the radial protuberance.
