<P>PROBLEM TO BE SOLVED: To provide a traveling vehicle such as a riding type work machine enabling stable and easy positioning of a traveling vehicle body after swiveling, when a steering wheel is operated to move to a working position of a next step immediately after swiveling. Ž<P>SOLUTION: In an intermittently turning on/off control function B1 for intermittently turning on/off the driving of a rear wheel on a steering inner side according to the operation of the steering wheel, though the control function B1 is in a non-operation state once by the returning operation of the steering wheel after actuating the control function B1, when the steering operation of the steering wheel is carried out, a rate of an in-state of a period turning in/off the driving force of the rear wheel on the steering inner side in the control function B1 is made to be smaller than a rate of an in-state during the previous actuation of the control function B1, thereby smoothly carrying out the steering of the traveling vehicle, so that the positioning of the traveling vehicle body after swiveling can be stably and easily carried out.
