Claims

[Scope of utility model registration request]

(1) An input drum 1, which is rotatable around the output shaft 3 and both having the same outer diameter, and an output drum 2, which rotates integrally with the output shaft 3, are supported in abutment on the same center, and each of the drums 1, A coil spring 8 made of a highly flexible and elastic synthetic resin and having an inner diameter smaller than the outer diameter of each drum 1.2 is wound around the outer circumference of each drum 1.2, and one end of the coil spring 8 is fixed on the output drum 2 side. The other end is fixed to the side of the desk 6 fitted to the input drum 1, and the frame 13 housing the solenoid 14 inside is sheathed on the coil spring 8, and between the end of the frame 13 and the desk 6 is the frame 13. A small clutch provided with a movable iron piece 16 which is driven by a solenoid 14 and engages with the disk 6 to prevent its rotation.

(2) The small clutch according to claim 1, wherein the coil spring 8 is made of polycarbonate, and the input drum 1 and output drum 2 are both made of synthetic resin.
