ABSTRACT:
In an electromagnetic spring-wound clutch, an input rotary member is concentrically and rotatably fitted on an output rotary member having an annular enlarged portion, with its axial boss disposed adjacent the above annular enlarged portion. A coil spring is wound around the axial boss and the annular enlarged portion for gripping engagement with at least the former, with its one end engaged by the output rotary member and its other end by a sleeve concentrically and rotatably supported on the input and output rotary members. An armature is disposed for axial tilting about its one edge supported by a stationary member. Responsive to extinction of electromagnetic force caused by deenergization of a magnetic coil, the armature is axially tilted by the force of a spring into engagement with the sleeve to hold same from rotating. When the armature is out of engagement with the sleeve, the coil spring is wound up into gripping engagement with the input and output rotary members to cause driving coupling therebetween.
