PROBLEM TO BE SOLVED: To provide a vehicle driving device that can drive an oil pump when an engine is stopped, and that restrains upsizing of the device.SOLUTION: A vehicle driving device comprises: a clutch 11 that arbitrarily transmits or interrupts power between an engine 2 and a speed change mechanism 20; a one-way clutch 12 that interrupts the transmission of power from the clutch to the engine; an oil pump 13 that is connected to a rotating shaft 7 connecting the clutch and the one-way clutch and driven by the rotation of the rotating shaft; and a torque converter 5 that is arranged between the engine and the clutch. The one-way clutch is arranged between the torque converter and the clutch. 【課題】エンジンを停止しているときにオイルポンプを駆動できることと、装置の大型化の抑制とを両立できる車両駆動装置を提供すること。【解決手段】エンジン２と変速機構２０との間で動力を任意に伝達あるいは遮断するクラッチ１１と、クラッチからエンジンへ向けての動力の伝達を遮断するワンウェイクラッチ１２と、クラッチとワンウェイクラッチとを接続する回転軸７に接続され、回転軸の回転によって駆動されるオイルポンプ１３と、エンジンとクラッチとの間に配置されたトルクコンバータ５とを備え、ワンウェイクラッチは、トルクコンバータとクラッチとの間に配置されている。【選択図】図１
