PROBLEM TO BE SOLVED: To provide a driving device for a hybrid vehicle which inhibits cost increase even when a transmission mechanism is used therein.SOLUTION: A driving device 1-1 for a hybrid vehicle includes: an engine 1; a first rotary machine MG1; a second planetary gear mechanism 20 serving as a differential part which connects the engine 1 and the first rotary machine MG1 with the driving wheel 32 side; and a transmission part (a first planetary gear mechanism 10, a clutch CL1, and a brake BK1) which changes a speed of rotations of the engine 1 and transmits the rotations to the second planetary gear mechanism 20. The engine 1, the first rotary machine MG1, the second planetary gear mechanism 20, and the transmission part are coaxially arranged. The second planetary gear mechanism 20 is disposed between the engine 1 and the first rotary machine MG1. The transmission part is disposed at the opposite side of the engine 1 with respect to the first rotary machine MG1. 【課題】変速機構を適用してもコスト増加を抑制できるハイブリッド車両用駆動装置を提供する。【解決手段】ハイブリッド車両用駆動装置１−１は、エンジン１と、第一回転機ＭＧ１と、エンジン１及び第一回転機ＭＧ１を駆動輪３２側に接続する差動部としての第二遊星歯車機構２０と、エンジン１の回転を変速して第二遊星歯車機構２０に伝達する変速部（第一遊星歯車機構１０、クラッチＣＬ１、ブレーキＢＫ１）を備える。エンジン１、第一回転機ＭＧ１、第二遊星歯車機構２０、及び変速部が、同軸上に配置され、第二遊星歯車機構２０が、エンジン１と第一回転機ＭＧ１との間に配置される。変速部が、第一回転機ＭＧ１を基準としてエンジン１と反対側に配置される。【選択図】図１
