PROBLEM TO BE SOLVED: To detect a turning angle of front wheels while avoiding enlargement of a king pin case or expensive cost. SOLUTION: The traveling vehicle for working comprises a center case 13, a pair of right and left the king pin cases 14 provided at right and left both end portions of the center case 13, a pair of right and left final cases 15 steering the front wheels 3 by rotations about the king pin cases 14, and a turning angle detecting switch 8 detecting the turning angle of the front wheel 3, in a front axle case 6 supporting a pair of the right and left front wheels 3 so as to freely steer. A turning angle detecting shaft 18 capable of rotating is provided in the center case 13. The turning angle detecting shaft 18 is coupled to the final cases 15 through an interlocking mechanism 19, and a rotation angle of the turning angle detecting shaft 18 interlocking with rotations of the final cases 15 is detected by the turning angle detecting switch 8.
