Claims

[Claims for Utility Model Registration] 1. An input shaft and an output shaft disposed in the axial direction, and a coil spring wound across both the input shaft and the output shaft, the coil spring being wound during operation. In a spring clutch in which a spring is tightened to connect the input shaft and the output shaft so that the torque of the input shaft is transmitted to the output shaft, at least the coil spring of the input shaft and the output shaft is connected. The cylindrical collars are respectively fitted to the outer circumferential surface of the lower part of the neck, which faces the inner circumferential surface of is molded and sintered to form a protrusion or a recess in the axial direction, and on the other hand, the outer circumferential surface of the lower part of the neck of the input shaft and the output shaft has a protrusion or a recess in the axial direction of the cylindrical collar. 1. A spring clutch characterized in that complementary recesses or protrusions are formed so that the two fittings cannot rotate relative to each other. 2. The spring clutch according to claim 1, wherein a plurality of protrusions or recesses are formed on the inner circumferential surface of the cylindrical collar, and a plurality of recesses or protrusions are also formed on the lower part of the neck of the input shaft and the output shaft. .
