Abstract
An apparatus for transmitting signals between a load-vehicle stationary unit and a control board mounted on a steering wheel. A light is utilized as a means for transmitting information. The control board is mounted on the steering wheel in a floating relation with such a structure that the relative position between the stationary unit and the control board remains unchanged. A plurality of light emitting elements and light receiving elements opposite to the formers are disposed at different positions in accordance with the shape and position of one or more spoke of the steering wheel, so that all light beams are not interrupted by the spoke of the wheel at the same time. The light emitting and receiving means are provided on each of the stationary unit and the control board to permit bidirectional transmission of signals.
