To provide a driving apparatus for hybrid vehicle for driving an oil pump by a motor generator, which has a configuration such that the revolution of the oil pump can be changed regardless of the running speed of the vehicle, and whereby the drive loss of the oil pump is reduced. In the case in which four rotating elements T1 to T4 are arranged on a collinear diagram, the rotating elements T1 to T4 are arranged on a straight line, an output shaft 3 of an engine 1 is connected, via a one-way clutch 21, to one T2 of the two rotating elements T2 and T3 arranged in the center of the collinear diagram, an output member 8 is connected to the other T3 of the two rotating elements T2 and T3, two motor generators 5 and 6 are connected to the two rotating elements T1 and T4 arranged at both ends of the collinear diagram, and an oil pump 22 is connected to either one of the two motor generators 5 and 6.
