ABSTRACT:
The disclosure relates to an apparatus for making an electrical connection between a steering wheel and a steering column in the steering system of a vehicle, and more particularly, to the apparatus having an indication for indicating the number of rotations of the steering wheel. The apparatus includes a stationary case to be fixed to the steering column, a rotor member rotatable together with the steering wheel, and a coiled tape member. This tape member provides an electrical connection between the steering wheel and the steering column and is accommodated in a case comprising the stationary case and the rotor member. The apparatus further comprises a sprocket mounted on the rotor member, an internal gear formed on the inner face of the stationary case, and a ring-shaped member rotatably provided between the sprocket and the internal gear. The ring-shaped member has a plurality of windows arranged in a pitch different from the pitch between the teeth of the internal gear. The sprocket engages with the internal gear through the windows of the ring-shaped member. The ring-shaped member will slightly shift relative to the stationary case when the rotor member rotates with the rotation of the steering wheel. The shift of the ring-shaped member can be detected by a change in relative position between the position mark indicated on the ring-shaped member and the position mark indicated on either the stationary case or the rotor member.
