PURPOSE: An up-and-down driving vehicle is provided to smoothly drive on even or uneven ground by walking or shaking body back/forth and leftward/rightward. CONSTITUTION: An up-and-down driving vehicle comprises a boarding plate and one or more of up-and-down driving devices(100). The up-and-down driving device comprises a connecting unit(2), a wheel part(3), an elastic unit(4) and a stopper(5). One end of the connection part of the advancing direction of the vehicle is connected to one end of a riding part or a horizontal part(1). One end of the connection part of the opposite direction of the advancing direction of the vehicle is connected to the wheel part. One or more wheels of the wheel part are rotated only in one direction. The elastic unit usually increases the folding angle of the riding part or the horizontal part to the connection part and if pressure is applied to the riding part or the horizontal part, the elastic unit decreases the folding angle. The stopper restricts the connecting angle of the riding part or the horizontal part to the connection part to be in an acute angle range. |
