PURPOSE:To contrive the reduction of a driving loss and prevention of wear of a driving wheel, by steering automatically a driven wheel and a driving wheel by driving force of the driving wheel in the direction offsetting turning force of a vehicle through driving force of the driving wheel. CONSTITUTION:When a right rear wheel 2 is driven by an output of a power train unit 15, the power train unit 15 together with a rear axle 16 are revolved counterclockwise centering around fixing points of a lateral rod 21 and the rear axle 16, and a shackle 26 is moved to a position 26'. With this construction, the right and left rear wheels 2, 6 are steered simultaneously, both the wheels 2, 6 are moved in the direction of toe-in and toe-out respectively, and both the wheels 2, 6 are steered in the direction offsetting left-handed turning force at the time of acceleration under a state of straight running by monowheel driving by the right rear wheel. At the time of deceleration they are steered in the reverse way. With this structure, a driving loss and wear of a driving wheel can be prevented. |
