Abstract
A vehicle capable of turning a vehicle body with a relatively small turning radius and with a good operability in a turning operation. One of front and rear pairs of left and right wheels, to which a running torque produced by a vehicle driving source is not transmitted, is arranged for rotation concerning respective axes perpendicular to the ground. For turning the vehicle body, the one pair of left and right wheels are fixed at angular positions along tangential directions of an arc which passes the axes perpendicular to the ground of the one pair of left and right wheels. At these angular positions, a rotating torque is applied to the one pair of left and right wheels to turn the vehicle body substantially about the center point of the rotating axle for running the vehicle of the other pair of left and right wheels.
