ROTARY CONNECTOR DEVICE

The present invention has an object of providing a steering roll connector 10 capable of rotating rotatable rollers 45 smoothly. The steering roll connector 10 includes a rotator 20 and a stator 30 which are rotatably engaged with each other. The rotator 20 and the stator 30 form an accommodation space S. In a bottom part of the accommodation space S, a retainer 40 for axially supporting a plurality of rotatable rollers 45 and flat cables C are accommodated. A bearing 43a included in the retainer 40 and a rotation shaft 435 included in each rotatable roller 45 are axially supported to be rotatable. The rotation shaft 453 includes a plurality of legs 455 located in a circumferential direction thereof and each having a sliding part T slidable against a circumferential surface 43b of the bearing 43a, and an engaging part 456 formed at a tip of each leg 455. At least the sliding part T of each leg 455 is formed to have a radial-direction cross-sectional shape which is point-contactable with the bearing 43a, or line-contactable with the bearing 43a over a contact width smaller than a circumferential-direction width of the leg 455.
