PROBLEM TO BE SOLVED: To minimize a transmission for a working vehicle that includes a transmission mechanism in a traveling system transmission path, and can take out vehicle speed synchronizing power from the traveling system transmission path to output to a working machine. SOLUTION: The transmission for the working vehicle includes: a variable driving shaft coaxially jointed to a motor shaft of an HST (Hydro Static Transmission) jointed to one side face of a transmission case to work together; a traveling system output shaft located at a lower part of the variable driving shaft roughly parallel to the variable driving shaft; a multi-stage transmission mechanism that transmits the power from the variable driving shaft to the traveling system output shaft; a differential mechanism for front wheels that differentially transmits the power from a front axle driving gear supported to the traveling system output shaft on one side in the vehicle width direction relative to driven gears of the multi-stage transmission mechanism to one pair of the front axle driving shafts; an output shaft for a rear axle jointed to the traveling system output shaft on one side in the vehicle width direction relative to the front axle driving gear to work together and to output the power to the rear axle; and an output shaft for the working machine jointed to a gear train including a working machine system driving gear supported to the variable driving shaft on the other side in the vehicle width direction relative to the driving gear of the multi-stage transmission mechanism to work together, and to output the power to the working machine.
