A driving device 1-1 for a hybrid vehicle includes a transmission unit capable of outputting a rotation of an engine 1 while changing rotating speed of the engine; and a first rotating electric machine MG1. The first rotating electric machine MG1 is configured to supply a torque for increasing the rotating speed of the engine at the time of starting up of the engine 1 to the engine 1 through the transmission unit. At the time of starting up of the engine 1, the gear shift stage of the transmission unit is switched to an overdrive state. Thus, a torque sufficient for starting up of the engine 1 can be supplied to the engine, and hence the engine 1 can be appropriately started up.
