To provide a vehicle oil supply device which includes oil pumps capable of operating independently and enables improvement of responsiveness of oil supply when driving of the stopped oil pump starts.SOLUTION: A vehicle oil supply device 80 includes a mechanical oil pump 40 and an electric oil pump 50 which can operate independently. A first suction oil passage 42 (an oil passage 42a and an oil passage 42b) allowing communication between a suction port 40a of the mechanical oil pump 40 and an oil strainer 92 and a second suction oil passage 52 (an oil passage 52a and an oil passage 52b) allowing communication between a suction port 50a of the electric oil pump 50 and the oil strainer 92 are formed independently. Further, the vehicle oil supply device 80 is formed with a first bypass oil passage 70 allowing communication between the first suction oil passage 42 and the second suction oil passage 52.SELECTED DRAWING: Figure 3 【課題】独立して運転可能な複数のオイルポンプ備え、停止していたオイルポンプの駆動が開始される場合におけるオイル供給の応答性を向上させられる車両用オイル供給装置を提供する。【解決手段】車両用オイル供給装置８０は、独立して運転可能な機械式オイルポンプ４０と電動式オイルポンプ５０とを備える。機械式オイルポンプ４０の吸入口４０ａ及びオイルストレーナ９２の間を連通する第１吸入油路４２（油路４２ａ、油路４２ｂ）と、電動式オイルポンプ５０の吸入口５０ａ及びオイルストレーナ９２の間を連通する第２吸入油路５２（油路５２ａ、油路５２ｂ）と、が独立して形成されており、第１吸入油路４２及び第２吸入油路５２を連通する第１バイパス油路７０が形成されている。【選択図】図３
