Abstract
A rotary connector includes a stator housing in which an outer tubular body is erected at an outer edge of a bottom plate having a center hole, an upper rotor having a top plate facing the bottom plate and an inner tubular body facing the outer tubular body, and rotatably mounted on the stator housing, a lower rotor having a tubular portion inserted through the center hole towards the top plate from the bottom plate and fixed to the inner tubular body, and an annular flange protruding radially outward from the tubular portion and faces the bottom plate, and a flexible cable housed within an annular housing space formed between the stator housing and the upper rotor so as to be able to be wound and rewound, and having one end attached to the stator housing and the other end attached to the rotor. An inner edge of the bottom plate is provided with an erected portion erected in an axial direction, and the erected portion is made to face the tubular portion such that an inner peripheral surface of the erected portion becomes a sliding surface of the tubular portion, and the erected portion is arranged between a bottom of the inner tubular body and the annular flange such that axial movement of the upper rotor and the lower rotor is suppressed by the erected portion.
