In a rotary connector in which a movable body rotating with rotation and revolution of a planetary gear and a flat cable having a reversed portion are housed within a housing space defined between outer and inner cylindrical bodies, restricting walls extending in the circumferential direction with an opening therebetween are erected on the movable body molded of resin, the reversed portion is passed through the opening, and the radial movement of the flat cable is restricted. A plurality of groove portions are formed in the inner peripheral surfaces of the restricting walls so as to be continuous with one another along the circumferential direction, and the depth d of the groove portions and the central angle theta corresponding to the length in the circumferential direction of the groove portions are set within ranges of 0.5 mm@d@2.0 mm and 5 degrees@theta@30 degrees. |
