PROBLEM TO BE SOLVED: To simplify the structure of a differential gear lock pedal, and to reduce the cost. SOLUTION: A front wheel differential gear switchable to a differential working condition and a non-differential working condition is provided on a transmission system to right and left steered front wheels, a differential gear lock pedal 18 for reversibly switching the front wheel differential gear from the working condition to the non-working condition by the step-in operation is provided, a return spring 19 for oscillating and urging the differential gear lock pedal 18 to the step-in operation starting position is provided. In constituting the differential gear lock pedal 18, a bent bar-like pedal body 20 having a support shaft 20A which is rotatably and pivotably supported by a frame 22, a step-in operation arm 20B which is continuously provided on one end of the support shaft 20A, and an arm 20C to be connected to the front wheel differential gear which is continuously provided on the other end of the support shaft 20A is provided.
