ABSTRACT:
A relay apparatus between relative rotary members has a first rotator (a rotator) having an inner cylindrical portion, a second rotator (a fixed body) having an outer cylindrical portion for surrounding the inner cylindrical portion at a predetermined interval, and for rotating relative to the inner cylindrical portion, a flexible flat cable coiled along the inside of the circular space between the inner cylindrical portion and the outer cylindrical portion, wherein the terminal portion of the inner circumference and the terminal portion of the outer circumference of the flexible flat cable are held in the inner cylindrical portion and the outer cylindrical portion, respectively, and a C-shaped mobile body is disposed in a freely movable manner for reversing the flexible flat cable in the aperture, wherein the mobile body is defined so that an inner circumferential side is polygon-shaped. The C-shaped movable member comprises a planar horizontal rib with a planar upper rib projecting vertically to contact the upper cover and a planar lower rib projecting to contact the lower cover and has a gap in its perimeter defined by first and second end portions, one having a concave and one a convex surface.
