Zusammenfassung:PROBLEM TO BE SOLVED: To provide a simply structured transmission which effectively prevents high-temperature return oil fed from an HST or hydraulic device to a case from being circulated and supplied to the HST or hydraulic device, keeping the high temperature, in the transmission having a mission case reserving oil. SOLUTION: The mission case is partitioned into a front chamber, an intermediate chamber, and a rear chamber communicating oil to each other by a front support wall and a rear support wall sequentially disposed in the longitudinal direction of the vehicle. The return oils from the HST and hydraulic device are made to flow into the front chamber and the rear chamber, respectively, and a hydraulic pump sucks the oil from the intermediate chamber.
