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