Abstract
A vehicle body (2) is provided with front wheels (3) installed to be turnable around vertical axes (27), front wheel turning means (30) for turning the front wheels, rear wheels (4.) installed to be turnable around vertical axes (49), and rear wheels turning means (50) for turning the rear wheels. The vertical axes (27, 49) of the front-and rear wheels (3, 4) are positioned outwardly of tread centers (3a, 4a) for longitudinal travel, so that on switching to transverse travel, the front wheels (3) can be turned laterally and forwardly and the rear wheels (4) can be turned laterally and rearwardly with respect to the vehicle body (2). This enables the center distances between the right and left wheels and between the front and rear wheels to be greater than those for longitudinal: travel, thus improving stability for transverse travel.
