Abstract

[Problem to be Solved] To provide a vehicle driving device (3) that can shorten an oil passage that passes through an oil cooler (7), and thus can reduce an overall size. [Solution] A vertical wall part (5A) of a case (3A) includes a partition wall part (5A1) and an outer wall part (5A2), the partition wall part (5A1) being located on the inner side of the case (3A) and supporting an input shaft (10), the outer wall part (5A2) partitioning an inside and an outside of the case (3A). An oil pump (30) is provided to the partition wall part (5A1) to be coaxial with the input shaft (10), and a strainer (26) is attached to the lower part of the inner surface of the outer wall part (5A2). An oil cooler (7) configured to cool oil is provided on the outer surface of the vertical wall part (5A), and the vertical wall part (5A) has a suction oil passage (31), a discharge oil passage (32), and a cooler inflow oil passage (33), the suction oil passage (31) being in communication with the strainer (26) and the oil pump (30), the discharge oil passage (32) being in communication with the oil pump (30) and an object to be lubricated, the cooler inflow oil passage (33) being in communication with the oil cooler (7). The cooler inflow oil passage (33) is formed on the outer wall part (5A2) along the suction oil passage (31).
