PURPOSE:To sharply reduce the minimum radius of gyration and improve a small-turning property by using a body bending steering device together with an Ackermann-Jeantaud type steering device and simultaneously operating both devices at the time of steering. CONSTITUTION:A front vehicle body 1 and a rear vehicle body 2 are linked to each other at a front and rear body joining point B, and the front and rear bodies 1, 2 can be revolved while being mutually bent by the operation of articulate cylinders 91, 92. Also, rear wheels 6 (61, 62) are installed so as to be revolved centering around their respective king pins 161, 162 and revolved by the operation of a steering cylinder 13 linked to a tie rod 8. And, the rear wheels 6 are inclined with respect to a rear axle 4 in such a way that when the point at which the perpendicular bisector of a line segment connecting the middle points of a front axle 3 and the rear axle 4 crosses the extension of the front axle 3 is defined as E, both normals erected on the faces of rear wheels 6 at the centers of the rear wheels 6 always pass through the point E regardless of the bent angle of the body.
