PURPOSE:To raise the efficiency of engine power over the whole range of car speed, by directly connecting the engine power to a hydro-mechanical transmission (HMT), not through a clutch, and setting an auxiliary sped change gear at its output side. CONSTITUTION:A flywheel 2, HMT 3, a forward/backward change gear 4, and an auxiliary speed change gear 5 are housed in a transmission case 1. A motor gear 14 for the hydraulic pump.motor 12 of HMT 3, is connected to a planet gear unit 16. Engine power is output to a cylindrical shaft 22 which is an output shaft, after being continuously changed by the hydro-mechanical transmission gear 3. This shaft 22 is equipped with the hydraulic clutch 30 of the forward/backward change gear 4, and the power is further transmitted to wheels, through being subjected to 1-2 or 2-4 steps speed change, by the auxiliary speed change gear 5.
