<p>PROBLEM TO BE SOLVED: To prevent generation of a collision sound even if a support collides with an inside case or the like due to vibration or impact applied to a rotary connector by preventing the support from moving in the rotational lengthwise direction of the rotary connector. SOLUTION: An outside case 2 is formed by combining a nearly cylindrical outer barrel part 2a and a disk-shaped outside case cover 2c having a circular hole in about the center. In this disk-shaped support 7, the support inner peripheral end 7b is supported by an outer peripheral groove 1a of an inside case 1 and the outside case cover 2c, and is sandwiched by an inner peripheral groove 2b of the outside case 2 and the outside case cover 2c. In the support 7, a relative movement in the direction parallel to the rotational axis of this case is prevented. Therefore, when vibration or impact is applied in the vertical direction, an axial directional relative movement to the inside case 1 and the outside case 2 of the support 7 is restricted within a certain limit. Therefore, a collision sound is not generated even if the support 7 moves and collides with the inside case 1 or the like due to vibration or impact.</p> |
