In a driving apparatus 10 for a hybrid vehicle having an internal combustion engine 12 and first and second electric rotating machines 14, 16, it is configured to have a speed increasing mechanism 24 that increases speed of an output of the engine inputted through an input shaft 22 and transmits it to the first electric rotating machine; a speed reducing mechanism 30 that reduces speed of an output of the second electric rotating machine and transmits it to an output shaft 26; a first clutch 34 adapted to connect and disconnect a first driving force transmission path 32 coupling the speed increasing mechanism and the output shaft; and a second clutch 40 adapted to connect and disconnect a second driving force transmission path 36 coupling the engine and the output shaft. The gear ratio can be changed between two ratios through the first and second clutches so that the engine output can be converted to more appropriate driving force. Consequently, when the vehicle runs with the engine output, options of a series/parallel running mode that enables the vehicle to run with smaller loss in electric power than a series-hybrid running (in which the engine output is converted to electric energy and the converted energy is again converted to the driving force) can be increased, thereby enabling to enhance fuel efficiency of the engine.
