<p>PROBLEM TO BE SOLVED: To provide a rotary connector, in which the rotation of a rotary case, in a prescribed number of times, in the wind-loosening direction of belt- shaped transmission lines is easily detected, so that the belt-shaped transmission lines do not obtain permanent bent part. SOLUTION: The rotary connector comprises the rotary case 2 and a fixed case 3 arranged in combination so that each case is free to rotate relatively and a circular space S is formed inside, and a plurality of belt-shaped transmission lines, which are wound around spirally and wound back in U-shape in the middle, and housed in the circular space S in the way whose one end is supported with the rotary case 2 and the other end with the fixed case, wherein both cases can be rotated relatively multiple times by the tightening and loosening of the belt-shaped transmission lines 6. Either of the rotary case or the fixed case is provided with a stopper for regulating the relative rotation of the rotary case 2 and fixed case 3 when the wound belt-shaped transmission lines are loosened to a prescribed position.</p> |
