To provide a driving gear of a hybrid vehicle which can downsize a size in a direction corresponding to a cross direction of the vehicle when attached to the vehicle.
A planetary gear 10 comprises a sun gear S fixed unrotatively by a clutch 13, a ring gear R connected to a rotor 61 of a second motor generator (M/G) 60, and a carrier CR connected to an input-output shaft 31 of an engine (E/G) 30. A first motor generator (M/G) 50 is arranged in parallel to the engine in a direction crossing with a rotation axis direction of each gear constituting the planetary gear. A rotor 51 of the first M/G is arranged substantially parallel to the input/output shaft of the E/G. A belt 40 is wound around the rotor of the first M/G and the input-output shaft of the E/G.
