PROBLEM TO BE SOLVED: To prevent overturn of a working machine for track without obtaining the reaction force to an outrigger from the ground. SOLUTION: A pair of right and left wheels 5 and a pair of right and left wheels 6 are mounted on a front part of a traveling truck 4; a pair of right and left wheels 7 and a pair of right and left wheels 8 are mounted on a rear part of the traveling truck 4; and the traveling truck 4 travels on rails by using these wheels 5-8. Two outriggers 18 are mounted on a front end face of the traveling truck 4. Right and left positions of the pair of outriggers 18 are arranged at the right and left positions of the pair of wheels 5 when viewed from the front side or the rear side of the traveling truck 4. When the outriggers extend downwardly, fore end ground contact legs 19 are butted on the rails 3, and the reaction force can be obtained from the rails 3 to prevent a working machine for track 1 from being overturned.
