Rotary connector

The present invention provides a rotary connector where capable of carrying out smooth winding and unwinding even when three or more flat cables are used. The rotary connector stores four flat cables that are received in an annular space formed between the stator and the rotor in state of being reversely wound on the way, and the flat cables are reversely through a first and a second opening, a holder may be rotatably disposed in the annular space. According to the rotary connector, the width of a first opening is set to be smaller than that the second opening, and the bending strength of thedriving side flat cable through the first opening is set to be higher than that of the second opening of the other three flat cables, the driving side flat cable are led from a cable lead-out portionof the inner cylindrical part toward the annular space, the driving side flat cable of the flat cables 4 is wound on the lowest portion of the outer peripheral surface of the inner cylindrical part.
