Claims

[Scope of utility model registration request]

an input rotating member concentrically supported on an output rotating member so as to be freely rotatable; an annular gap formed between the input rotating member and a sleeve supported concentrically and freely rotatably; and one end attached to the sleeve. Further, a coil spring for winding, the other end of which is hooked to the output rotating member and housed in the annular gap, and has a winding tendency to tighten the input rotating member; and one end surface of the sleeve. A field core with a built-in electromagnetic coil arranged on the same axis as the output rotating member with a predetermined gap between the field core and the end surface of one side of the sleeve due to magnetic attraction to the field core and demagnetization. In an electromagnetic spring clutch having a plate-shaped armature that can freely tilt in a direction and prevent rotation of the sleeve, the output rotating member, which is hooked at one end of the coil spring, is provided with a plate-shaped armature. An electromagnetic spring clutch comprising a wide notch and a convex portion on the armature that can freely prevent rotation of the output rotating member by engaging the notch.
