PURPOSE: To improve the stability in running by making a follow-up axle (rear axle) in a bus driven and guided on a special road provided with guidance bars on both sides of a road surface turn centered on a vertical shaft on a rear side of a central position in the axial direction by predetermined shearing stress. CONSTITUTION: A bus 36 guided and run on a special road 1 can be manually steered and is provided with a front wheel steered through a guidance roller which comes into roll-contact with guidance bars 3 on both sides of a road surface 2 and a follow-up type rear wheel 7. A shaft part 15 of the rear wheel 7 is turnable centered on a vertical shaft 8 on a rear side in the direction of running, and a rear axle is driven by an engine 16. In this case, the shaft part 15 supports a vehicle body 19 by a pair of pulling bars 20 arranged trapezoidally, and one end of each pulling bar 20 is supported in an intermediate part of a spring receive metal unit 13 receiving a vehicle body load in an air spring type bellows 14 at a tip thereof. Moreover, the shaft part 15 is supported on a vehicle body 19 side by a pair of guide bars 24 arranged triangularly. |
