In a rotary connector where a moving body turning with the rotation and revolution of a planetary gear and a flat cable including an inverted portion at a middle portion thereof are received in an annular space defined between an outer cylindrical body of a stationary-side housing and an inner cylindrical body of a movable-side housing, regulating walls, which extend in a circumferential direction with an opening interposed therebetween, are erected on a moving body formed of a resin molded product and the inverted portion passes through the opening so that the movement of the flat cable in a radial direction is regulated. Further, a plurality of protrusions, which protrude toward the inner peripheral surface of the outer cylindrical body, are repeatedly formed in the circumferential direction on the outer peripheral surfaces of the regulating walls.
