To provide a vehicular driving device which can properly lubricate a portion needing lubrication regardless of a traveling state of a vehicle.SOLUTION: A vehicular driving device includes: a first connection oil passage 74 which connects a first supply oil passage 71 for supplying an oil to a differential gear mechanism 2 for distribution with a first hydraulic pump 61; a second connection oil passage 75 which connects a second supply oil passage 72 for supplying the oil to rotary electric machines MG1, MG2 with a second hydraulic pump 62; a third connection oil passage 76 which connects a third supply oil passage 73 for supplying the oil to a power transmission mechanism 3 and a differential gear mechanism 4 for output with the second hydraulic pump 62; and a fourth connection oil passage 77 which connects the first connection oil passage 74 with the second connection oil passage 75. A first check valve 81 is provided at the upstream side of a connection portion of the first connection oil passage 74 connected to the fourth connection oil passage 77, and a second check valve 82 is provided at the upstream side of a connection portion of the second connection oil passage 75 connected to the fourth connection oil passage 77. A maximum discharge amount of the second hydraulic pump 62 is larger than a maximum discharge amount of the first hydraulic pump 61.SELECTED DRAWING: Figure 3
