Abstract
A transmission case includes: a main transmission input shaft to which the driving force is transmitted from the engine; and a main transmission output shaft fit on the main transmission input shaft in a relatively rotatable manner. The main transmission input shaft is provided with a hydraulic pump unit, a cylinder block, and a fixed capacity hydraulic motor unit, forming a hydraulic mechanical transmission, arranged in series. Shifted driving force is transmitted to the main transmission output shaft via the fixed capacity hydraulic motor unit. The transmission case includes a planetary gear mechanism and a transmission shaft with which the shifted driving force via the main transmission output shaft and the combined driving force via the planetary gear mechanism can be transmitted.
