Abstract
A rotary connector, in which a guide ring is disposed in an annular space in such a manner that the guide ring elastically contacts with the lower side of the cover portion of an inner case, and the intermediate supporting portion of each of a plurality of cylindrical rollers is rotatably supported by the guide ring in the state that the rotation axis of each roller slants, also both end-sides of each roller contact with a flat cable, also the circumference-side of each roller contacts with the upper side of a lower-side-cover. The above structure realizes a highly reliable low cost rotary connector in which a noise caused by the each-other's bumps of the component parts of the rotary connector is suppressed and the stress applied to the flat cable is greatly decreased.
