Abstract
In a belt clip for portable electronic equipment by use of rewind urging force of a torsion coil spring, a detachment preventing mechanism of a guide shaft, serving as a shaft center of a rotational mechanism, is implemented with a simple structure so as to improve a reduction in the number of parts and yield. The respective shaft support portions and of a hang stopper plate and both side plates and of a bracket are combined with each other, a torsion coil spring is twisted from a natural state and interposed therebetween in such a manner that a guide rod is passed through a space formed therebetween, but movement of the torsion coil spring to an axial direction and a change in a coil length are restrained by a groove of the hang stopper plate and the side plate of the bracket . Therefore, the torsion coil spring is skewed in the twisted state and a round line of the end portion is pressed to the guide rod , but a concave groove is formed at the corresponding position of the guide rod , and the round line is fitted into the concave groove to stop the guide rod
