Abstract
An electromagnetic spring-wound clutch is disclosed. An armature plate member to which one end of a coil wound spring is connected is flexibly connected to a guide member rotatably supported on a cover plate by a plurality of leaf springs. The cover plate has a bent portion at its axial terminal end and the guide member is closely fitted against the bent portion to maintained its axial position thereon. Thus, the armature plate is fitted against an axial end of the bent portion due to the recoil strength of the coil wound spring.
