To reduce the size of a vehicle drive device in the axial direction.SOLUTION: In a vehicle drive device 100, when expressing: a first ring gear 12 and a second sun gear 21, which are connected with each other to be integrally rotatable, as a first rotating element T1; a first carrier 14 as a second rotating element T2; a first sun gear 11 and a second carrier 24, which are connected with each other to be integrally rotatable, as a third rotating element T3; and a second ring gear 22 as a fourth rotating element T4, the first rotating element, the second rotating element, the third rotating element and the fourth rotating element T4 are configured such that respective rotation speeds of them satisfy a collinear relationship in which the respective rotation speeds are arranged in this order in a collinear figure. The first rotating element T1 is connected to a first motor 2, the second rotating element T2 is connected to an output member 8 that transmits power to drive wheels, the third rotating element T3 is connected to an internal combustion engine 1, and the fourth rotating element T4 is connected to a second motor 3. A first planetary gear mechanism 10 is located inside a rotor 2r of the first motor 2, and a second planetary gear mechanism 20 is located inside a rotor 3r of the second motor 3.SELECTED DRAWING: Figure 1 【課題】車両駆動装置の軸方向の小型化を図る。【解決手段】車両駆動装置１００は、互いに一体回転可能に接続された第１リングギヤ１２、第２サンギヤ２１を第１回転要素Ｔ１とし、第１キャリア１４を第２回転要素Ｔ２とし、互いに一体回転可能に接続された第１サンギヤ１１、第２キャリア２４を第３回転要素Ｔ３とし、第２リングギヤ２２を第４回転要素Ｔ４としたときに、第１、第２、第３、第４回転要素Ｔ４は、それぞれの回転数が共線図においてこの順で並ぶ共線関係を満たすように構成されており、第１回転要素Ｔ１が第１モータ２に接続され、第２回転要素Ｔ２が駆動輪に動力を伝達する出力部材８に接続され、第３回転要素Ｔ３が内燃機関１に接続され、第４回転要素Ｔ４が第２モータ３に接続され、第１遊星歯車機構１０が、第１モータ２のロータ２ｒの内側に配置され、第２遊星歯車機構２０が、第２モータ３のロータ３ｒの内側に配置される。【選択図】図１
