ABSTRACT:
A relay device includes a first rotor having an inner cylinder, a second rotor having an outer cylinder, a flexible flat cable wound spirally in an annular space defined between the inner cylinder and the outer cylinder and a C-shaped moving member arranged so as to move along the annular space. The C-shaped moving member consists of an inner horizontal rib, an outer horizontal rib, an upper vertical rib and a lower vertical rib. When the flexible flat cable is rewound from the inner cylinder by the relative rotation between the inner cylinder and the outer cylinder, the contact area of the moving member with the cable can be reduced because the inner horizontal rib is in the form of a plate material projecting from the inner peripheral face of the moving member horizontally. Thus, it is possible to reduce the frictional force of the moving member on the cable and to prevent the cable from buckling.
