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. a coil spring for winding, the other end of which is hooked to the output rotating member, the coil spring is housed in the annular gap, and has a winding tendency to tighten the input rotating member; A field core with a built-in electromagnetic coil arranged on the same axis as the output rotating member with a predetermined gap between it and the side end face, and a field core with a built-in electromagnetic coil that is erected by magnetic attraction to the field core and a part of the sleeve that is demagnetized by demagnetization. An electromagnetic spring clutch comprising a plate-shaped armature that can freely tilt in the direction of a side end surface and prevent rotation of the sleeve, wherein the armature has an overhanging bent part whose tip faces the back surface of the flange part of the sleeve. The electromagnetic spring cooler latch further comprises, on the back surface of the flange portion, an engaging portion with which the tip of the protruding bending portion engages when the armature is energized, and a non-engaging portion with which the armature is not engaged.
