PURPOSE: To stabilize a vehicle body by making it possible to run always on a flat surface by directing a wheel which tends to climb a sloped surface to the opposite direction and disposing a chassis at a low position.
CONSTITUTION: A front axle 2 and a rear axle 4 are made to be capable of swiveling in oblique directions by attaching an attachment shaft 225, secured in a tilted attitude to the center of the front axle 2, to a tilted holding cylinder 3 and connecting a tilted support frame 6 supporting a main unit 51 of a transmission 5 supporting the rear axle 4 to a holding plate 18 of a chassis by means of a pin 61. An engine E for driving the front axle 2 or rear axle 4 to rotate is mounted on the chassis 1. A reverse rotation mechanism for rotating one of the axes in opposite direction by means of the engine is employed. Stoppers 81 and 82 are provided to be linked to respective axes. A stopper switching mechanism is employed to link the stopper with the rear axle relative to the running direction and to separate the stopper from the front axle.
