Abstract
A rotatable connector in which a moving body provided with first and second openings are rotatably arranged within a storage section defined between a stationary housing having an outer cylindrical wall and a movable housing having an inner cylindrical wall; and the width W.sub.1 of the first opening and the width W.sub.2 of the second opening are set as W.sub.1 <W.sub.2. The first and second flat cables with both ends thereof fixed on the peripheral surfaces of the outer cylindrical wall and the inner cylindrical wall are wound within the storage section. The turned-back portions of the flat cables are routed through the first and second openings, with the inner end of the first flat cable directly wound around the peripheral surface of the inner cylindrical portion and with the inner end of the second flat cable also wound on the inner cylindrical portion through about one turn of the flat cable, thereby changing the winding diameter of the flat cables in relation to the inner cylindrical portion.
