PROBLEM TO BE SOLVED: To shorten the longitudinal length of a transmission case by disposing a pump and a motor constituting a static hydraulic continuously variable transmission at an engine side of an epicyclic gear mechanism inputting an engine motive power through an input shaft in a state that the pump and the motor are separated at both sides of the input shaft. SOLUTION: A transmission M is constituted by installing a fly wheel with a pulsation absorbing mechanism transmitting an engine output shaft to an input shaft 3, HST 4, an epicyclic gear mechanism 5, a sub-transmission mechanism 6 for traveling, a differential mechanism 7 for a rear wheel, a PTO intermediate shaft 8, a PTO clutch 9, a DT interlocking mechanism 10 for driving a front wheel and a shaft 11 for driving a front wheel in a transmission case 1. A variable pump 4p and a variable motor 4m constituting the HST 4 are separated at right and left below the input shaft 3 disposed at the front end of the transmission case 1 disposed in parallel such that the pump shaft 12 and the motor shaft 13 are transversely positioned each other. Thereby, compactification of the whole length of the transmission case can be realized.
