Abstract
A relay mechanism for a steering wheel comprising a plurality of slip rings disposed isolated from each other in a circular track having a steering shaft as its center, and sliders, one provided at each slip ring. It further includes an arcuate common line slip ring extending so as to have a predetermined central angle, and a common line slider sliding on the common line slip ring with the steering shaft as its center, the common line slider being positioned at the midpoint of the common slip ring when the steering wheel is at its straight travel position. When the steering wheel is turned over more than a predetermined angle from its travel position, the common line connecting the slip rings and a power source is rendered non-conductive thereby to disable the signal transmission between the slip rings and electric devices.
