To realize a vehicle drive device which comprises an input shaft, a rotating electric machine, an output differential gear mechanism and a transmission and can be easily mounted on a vehicle.SOLUTION: A vehicle drive device 100 comprises: an input shaft I which is arranged coaxially with an internal combustion engine output shaft ES, an output shaft of an internal combustion engine EG and is connected to the internal combustion engine output shaft ES so as to transfer drive force; a rotating electric machine MG1; an output side differential gear mechanism DF1 which distributes rotation to be input to a pair of wheels W1; and a transmission TM which transmits rotation transmitted from the input shaft I and the rotating electric machine MG1 to the output side differential gear mechanism DF1 by changing a rotation speed with a selected gear ratio. The input shaft I is arranged on a first axis X1. The transmission TM is arranged on a second axis X2 which is different from the first axis X1. The rotating electric machine MG1 and the output side differential gear mechanism DF1 are arranged on a third axis X3 which is different from the first axis X1 and the second axis X2.SELECTED DRAWING: Figure 1 【課題】入力軸、回転電機、出力用差動歯車機構、及び変速機を備えた構成において、車両への搭載性を高く確保しやすい車両用駆動装置を実現する。【解決手段】車両用駆動装置１００は、内燃機関ＥＧの出力軸である内燃機関出力軸ＥＳと同軸に配置され、内燃機関出力軸ＥＳに駆動連結される入力軸Ｉと、回転電機ＭＧ１と、入力される回転を一対の車輪Ｗ１に分配する出力用差動歯車機構ＤＦ１と、入力軸Ｉ及び回転電機ＭＧ１の側から伝達される回転を、選択された変速比で変速して出力用差動歯車機構ＤＦ１の側へ伝達する変速機ＴＭと、を備える。入力軸Ｉが、第１軸Ｘ１上に配置され、変速機ＴＭが、第１軸Ｘ１とは異なる第２軸Ｘ２上に配置され、回転電機ＭＧ１及び出力用差動歯車機構ＤＦ１が、第１軸Ｘ１及び第２軸Ｘ２とは異なる第３軸Ｘ３上に配置されている。【選択図】図１
