WORK VEHICLE

PROBLEM TO BE SOLVED: To minimize the impossibility of travel, since a work vehicle cannot occasionally travel when a rear wheel is up in the air in a recessed part by being supported by a front wheel and a jack with front-rear rollers, when the rear wheel is positioned in the recessed part and the front wheel and the front-rear rollers are positioned in a projection part, when the ground surface is a recess-projection, when an arranging distance between the rear wheel and the jack with the rollers is separate, when performing work while moving the vehicle by grounding the rollers on the ground surface by the jack with the rollers. SOLUTION: In this work vehicle, a work machine A is mounted on the vehicle 1 of rear wheel driving travel. An outrigger 4 for supporting the work vehicle on the ground surface is respectively arranged in front and rear lateral positions of the rear wheel 3. The roller jack 8 having the roller 7 on the lower end and supporting the vehicle 1 by the roller 7 by extending in a range without floating the rear wheel 3, is laterally arranged by two units only between the rear wheel 3 and the outrigger 4 arranged in the rear of the rear wheel 3.
