To provide a running vehicle which smoothly performs a fine adjustment in its running direction.
This running vehicle has a pair of right and left crawler type running devices, a right HST and a left HST acted as a driving device for the running devices. This running vehicle is operated such that the pair of running devices are driven by one right HST (or left HST) during the straight forwarding motion and each of the running devices is driven by the driving device corresponding to each of the running devices during a turning motion. A right turning switch 21r (or a left turning switch 21l) is operated to drive a right HST electric motor 27 (or a left HST electric motor 28). A speed difference is generated between running speeds of the right and left running devices to cause the vehicle to be turned only for a time set at a fine adjustment ON timer, thereby the running vehicle is turned smoothly when the running vehicle is finely adjusted in its running direction.
