<p>PROBLEM TO BE SOLVED: To facilitate the positional adjustment of a stopper in a spring clutch used for controlling the operation and stop of a device or a mechanism. SOLUTION: A first engaging part 22 of a coil spring 20 is engaged in an engaging groove 31 in a ring member 30 which can be rotated, relative to a stopper 51 in a stop collar member 50, without directly being engaged with the latter. Further, an elongated hole 53 is formed in the stopper 51 so as to fix the ring member 30 and the stop collar member 50 together by means of a screw or a pin 70 while the position or phase of the stopper 51 is adjusted.</p> |
