<p>PURPOSE:To prevent the structure of a steering wheel part from becoming complicate and increasing in capacity by arranging only irreducible necessary devices on a steering operation board. CONSTITUTION:A constant voltage power source device 70, microcomputer unit 80 which controls operation on the steering operation board, key switch 90, FMS modulating and demodulating circuits 100 and 110, microphone MC, differential amplifier DFA, FM modulator 95, monitor television TV as a surface display device, tuner TU, distributor 190, etc., are arranged on the steering operation board. Then, other circuits or a control unit is arranged on the side of a vehicle body. The both are connected together by the connecting mechanism consisting of a slip ring SA and brushes BA.</p> |
