To make both supply of oil to a speed changer and supply of oil to a rotary electric machine compatible with each other.SOLUTION: A vehicular driving device is disclosed, comprising: a speed changer arranged on a power transmission path extending from an internal combustion engine at a front part of a vehicle to a rear wheel; a rotary electric machine arranged concentrically with a speed-change output member, at a side closer to the rear wheel than the speed changer in the power transmission path; a first oil passage passing on the inside in a radial direction in the speed changer, concentrically with the speed-change output member; a second oil passage passing on the inside in the radial direction in the rotary electric machine, concentrically with the speed-change output member; a mechanical first oil pump that suctions and discharges oil in an oil pan; a first supply oil passage including a valve body, whose one end is connected to a discharge-side of the first oil pump and whose other end is connected to the first oil passage; an electrically-driven second oil pump that suctions and discharges oil in the oil pan; and a second supply oil passage, provided independently from the first supply oil passage, whose one end is connected to a discharge-side of the second oil pump and whose other end is connected to the second oil passage, where the first oil passage and the second oil passage communicate with each other.SELECTED DRAWING: Figure 3
【課題】変速機への油の供給と回転電機への油の供給とを効率的に両立させる。【解決手段】車両前部の内燃機関から後輪までの動力伝達経路に配置される変速機と、動力伝達経路における変速機よりも後輪側に、変速出力部材に同軸に配置される回転電機と、変速出力部材に同軸に変速機における径方向内側を通る第1油路と、変速出力部材に同軸に回転電機における径方向内側を通る第2油路と、オイルパン内の油を吸入して吐出する機械式の第1オイルポンプと、バルブボディを含み、一端が第1オイルポンプの吐出側に接続され、他端が第1油路に接続される第1供給油路と、オイルパン内の油を吸入して吐出する電動式の第2オイルポンプと、第1供給油路とは別に設けられ、一端が第2オイルポンプの吐出側に接続され、他端が第2油路に接続される第2供給油路と、を備え、第1油路と第2油路は、互いに連通する、車両用駆動装置が開示される。【選択図】図3
