Abstract
An apparatus for connecting two wirings on the sides of a steering wheel and a steering column includes a case assembly having a stationary casing and a rotor with a lid for the casing, and a coil-shaped cable member accommodated in the case assembly. The casing has an internal gear at its upper section, the internal gear being arranged to cross a rotational axis of the rotor at right angles. A ring-shaped gear which is engaged with the internal gear is rotatably arranged inside the internal gear as well as on the lid. Both gears are so designed that the number of teeth on the gear is smaller than that of the internal gear. A biasing mechanism for biashing the gear to the internal gear is provided for the lid. Further, an indication scale is arranged on a front surface of the gear for cooperating with a mating mark which is provided for the casing or the lid. When the rotor turns in any one direction, the biasing mechanism moves in the same direction while it biases the gear to the internal gear. There is a discrepancy in the number of gear teeth between the two. Consequently, the gear moves along its circumferential direction a minimal amount for every one turn of the rotor.
