PROBLEM TO BE SOLVED: To make a whole vehicle body compact. SOLUTION: This working vehicle is provided with a straight continuously variable transmission increasing and reducing rotating speed of a straight driving power transmission system, a turn continuously variable transmission increasing and reducing rotating speed of a turn driving power transmission system, and a transmission part composing rotating speeds of the straight driving power transmission system and the turn driving power transmission system and driving a left and right pair of crawler type traveling part individually at a composed rotating speed. One of the straight continuously variable transmission or the turn continuously variable transmission is arranged on a side wall of the transmission part with putting a longer length thereof in a vertical direction and another is arranged at an upper rear position of the one with putting a longer length thereof in a front and rear direction. A transmission case transmitting power to the traveling part is arranged in a space formed by the transmission part, the straight continuously variable transmission, and the turn continuously variable transmission.
