    摘要: The present invention relates to an electromagnetic spring clutch. A conventional field core is formed in a bottomed cylindrical shape, so manufacturing such a field core is troublesome and uneconomical. When a through-hole through which shafts are inserted is provided in one or both of vertical walls of a U-shaped plate, a field core is provided simply and inexpensively.

    摘要: An electromagnetic spring clutch has an armature (40) which can be moved to and from in the axial direction thereof and cannot be rotated on the axis, and which is biased by a spring (46), and a coil spring (36) which covers over outer faces of a master driving axle (30) and a slave driving axle (34) and which is capable of being wound tightly in the rotational direction of the master driving axle (30). When an electromagnetic coil (20) is not energized, an engagement section (44a) at the end of the armature (40) and a hook (38) of the coil spring (36) are engaged to expand the inner diameter of the coil spring (36) and disconnect the master driving axle (30) and the slave driving axle (34). When the electromagnetic coil (20) is energized to attract the armature (40) thereto against the biasing force of the spring (46), the engagement section (44a) and the hook (38) are disengaged to reduce the inner diameter of the coil spring (36) and connect the master driving axle (30) and the slave driving axle (34), whereby a prescribed rotational angle of the master driving axle (30) is transmitted to the slave driving axle (34).
