Abstract
A steering wheel for a vehicle has a switch-supporting pad kept stationary at all times regardless of turning movement of the steering wheel. The steering wheel incorporates a cable for electrically connecting vehicle electric accessories such as a radio, turn signal lights, and headlights to switches mounted on the pad for controlling the electric accessories. The cable is composed of a first loosely coiled spiral positioned in a housing section in a sun gear attached to the pad, a second loosely coiled spiral positioned in a housing section in a sun gear attached to a column, and a connecting portion joining the first and second spirals and extending axially through a boss plate mounted on a steering shaft.
