PROBLEM TO BE SOLVED: To miniaturize a machine body and reduce its weight by easily simplifying the drive configuration of a running member such as a running crawler. SOLUTION: In this work vehicle transmitting driving forces for straight advance and turn of a hydraulic continuously variable transmission member 25 and a steering member 28 to right and left running member 2 through right and left planetary gear mechanisms 35 to advance straight, turn, and run the machine body, the hydraulic continuously variable transmission member 25 and the hydraulic continuously variable steering member 28 are arranged on opposing side faces of a transmission case 22, and the right and left running members 2 are arranged on lower sides of the continuously variable transmission member 25 and the steering member 28 so as to lap them.
