ABSTRACT:
A rotating connector1comprising a rotating case2and a stationary case3connected together in a manner that the rotating case2can rotate relative to the stationary case3and that an annular space S is formed inside, and a plurality of flat cables6, 7held in the annular space S. In the annular space S, the flat cables6, 7are wound like a swirl, being U-turned at about the middle thereof with the help of a roller8arranged in the space S, and fixed to the rotating case2at one end and the stationary case3at the other end. The rotating case2can rotate relative to the stationary case3a plurality of times, with the winding of flat cables6, 7being tightened or loosened. The flat cable7is smaller in thickness than the flat cable6which is U-turned by being directly guided by a U-turn roller9.Thus, the flap noise which tends to be produced when the winding is tightened is reduced or prevented.
