Abstract
A rotary connector which prevents separation of a resilient tongue from a flexible cable so as to prevent buckling. The rotary connector includes first and second housings rotatably connected together and forming an annular space therebetween. A flexible cable and a movable member are received in the annular space. The movable member includes a turntable having a stationary cylinder and a reversing roller, the stationary cylinder including a guide projection. The flexible cable is wound in opposite directions on opposite sides of the movable member and includes a U-shaped reverse portion extending through a gap between the stationary cylinder and the reversing roller. A resilient tongue having a free end portion substantially formed in a linear shape in an unloaded condition is affixed to an inner surface of the flexible cable and to an inner cylinder portion of the second housing. An amount of deformation of the free end portion when it is bent between the stationary cylinder and the reversing roller can be reduced, thereby preventing separation of the tip of the resilient tongue from the flexible cable.
