PROBLEM TO BE SOLVED: To provide a work vehicle capable of strengthening the supporting structure of the mission portion as well as driving wheels, thereby securing excellent traveling performance of running portions. SOLUTION: A front left-right connection frame (20) is set horizontally between front portions of two running frames (10, 10), while a mission portion (5) is installed between a front column (31), erected on the left-right connection frame (20), and the rear columns (77, 77), erected behind the two running frames (10, 10); the rear columns (77, 77) are arranged so as to individually support two driving wheels (15, 15), while a rear left-right connection frame (21) is set horizontally between the two rear columns (77, 77), all in an integrated configuration.
