Claims

[Scope of utility model registration request]

A driven shaft that is fitted around the rotating shaft to rotate, a driving shaft that is loosely fitted to the rotating shaft, a spring that is fitted to the driven shaft and the driving shaft, and a rotational force cutoff that is fitted to the outer periphery of the spring. In the spring clutch, the spring clutch has a cam, the end of the spring is locked by a rotational force cutoff cam, and rotation is transmitted by the winding force of the spring, in which a metal core wire is inserted through the outer wire of the spring made of plastic. 1. A spring clutch characterized in that the driving shaft and the driven shaft are made of plastic.
