<p>PURPOSE:To maintain operating switches to be stationary even at the time of a steering operation and enhance operability, by a method wherein operating switches are provided at the upper end of a stationary shaft fitted with a steering wheel, and the steering wheel and a steering shaft are connected to each other by a transmission mechanism. CONSTITUTION:The steering wheel 14 is fitted to the stationary shaft 8, and an arm 10 of the shaft 8 is fixed by a fixing piece 12. A switch block 21 provided with a plurality of operating switches 20 is fitted to the upper end of the shaft 8, and lead wires 22 for the block 21 are led out through a taking-out hole 23 provided in the shaft 8. The steering shaft 5 is connected to the steering wheel 14 by the transmission mechanism consisting of gears 7, 16, a rotary shaft 17 and transmission gears 18, 19. Accordingly, since the operating switches are maintained to be stationary irrespective of the steering operation, operability is enhanced.</p> |
