ABSTRACT:
A rotary connector including a moving member (5) provided with first and second openings (14, 15) which is disposed in a holding space (10) formed between a fixed housing (1) having an upper case (6) and a movable housing (2) having a lower case (7) such that the moving member coaxially rotates with the movable housing (2) relative to the fixed housing (1). A width (W.sub.1) of the first opening (14) is made smaller than a width (W.sub.2) of the second opening (15) (i.e., W.sub.1 <W.sub.2). First and second flat cables (3, 4) are wound in the holding space (10) and have both ends thereof respectively fixed to the peripheral surfaces of the upper case (6) and the lower case (7), and reversal portions (3a, 4a) of the flat cables (3, 4) are passed through the first opening (14) and the second opening (15). The first flat cable (3) is directly wound on the cylindrical section (9) of the first flat cable (3), while the second flat cable (4) is wound on the first flat cable (3) so that the flat cables (3, 4) have different winding diameters relative to the inner cylindrical section (9).
