Abstract:
1. A rotary connector device, comprising: a stator and a rotator which rotates with respect to the stator concentrically with a steering; an accommodating space having a ring shape in a plan view, which is formed inside the stator and the rotator, and which accommodates a cable for electrically connecting the rotator and the stator in a wound state; and a retainer which is located on a bottom surface of the accommodating space so as to be able to guide the cable to rotate concentrically circle with the steering, wherein the rotator includes an inner peripheral tube portion which forms an inner peripheral surface of the accommodating space; and wherein the rotary connector further comprises: a rotator side abutting portion, which abuts an upper surface inner peripheral portion of the retainer in a slidable manner, formed on a lower portion of the inner peripheral tube portion; a retainer side abutting portion, which abuts the lower portion of the inner peripheral tube portion in a slidable manner, formed on the upper surface inner peripheral portion of the retainer; and a protruding abutting portion being formed on at least one of the rotator side abutting portion and the retainer side abutting portion so as to protrude toward the other and contacting the rotator side abutting portion; and a trench formed at a side, which faces a rotation axis of the stator and rotator, of the protruding abutting portion, the trench comprising an inclined surface that becomes gradually shallower toward the rotation axis of the stator and rotator.
