ABSTRACT:
A transaxle comprising a transmission, a pair of coaxial axles, a deceleration assembly for decreasing output rotational speed of the transmission, a differential assembly for transmitting power from the deceleration assembly to the pair of axles, and a common housing incorporating the transmission. The differential assembly includes a pair of gear train units disposed on the respective axles, and a bull gear for receiving output rotation of the deceleration assembly. Each of the gear train units includes a sun gear fixed on each of the axles, a holder relatively rotatably provided on each of the axles, and a planetary gear supported by the holder to mesh with the sun gear. The holders of the pair of gear train units are symmetrical with respect to a surface perpendicular to the pair of axles and joined to each other through the surface, and integrally fitted together in the bull common gear.
