ABSTRACT:
A cable reel which electrically connects a fixed portion and a movable portion using a flexible strip cable wound numerous times and received between the fixed portion and the movable portion is provided. A plurality of engaging portions are formed as predetermined gaps around the circumference of the fixed portion. A stopper member projects outside the movable portion and elastically presses toward the engaging portion so that the engaging portion engages the stopper member, thereby locking rotation of the movable portion. The engagement of the stopper and the engaging portion is automatically released, and it is possible to freely rotate the movable portion when the cable reel is assembled with a rotating mechanism.
