Claims

[Scope of utility model registration request]

The output rotating member, the input rotating member, and the field core are arranged on the same axis, and one end of a coiled clutch spring with a diameter-reducing sliding property that can be freely tightened to the boss portion of the input rotating member is attached to 1. The other end is hooked to a sleeve supported concentrically with respect to the input rotation member and the output rotation member on the output rotation member side, while the proximal end is swingably supported on the field core side, and an armature that can freely tilt elastically in the direction of the end surface of the sleeve,
The armature and the sleeve are relatively connectable,
Furthermore, a coiled brake spring that can be freely wound around the output rotating member and has one end hooked to the output rotating member and the other end hooked to the sleeve, and An electromagnetic spring clutch/brake that is equipped with a coiled reverse prevention spring that has a diameter-reducing behavior that fits over the outer circumferential surface of the same diameter.
