Abstract

To provide a vehicle driving device (3) that can maintain an appropriate oil temperature, and thus can enhance fuel efficiency.[Solution]A case (3A) includes a vertical wall part (5A) that supports an input shaft (10), and that extends in an up-down direction to partition an inside and an outside of the case (3A). 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) causing a strainer (26) and an oil pump (30) to be in communication with each other, the discharge oil passage (32) causing oil to flow from the oil pump (30) toward an object to be lubricated, the cooler inflow oil passage (33) being branched from the discharge oil passage (32) and causing the discharge oil passage (32) and the oil cooler (7) to be in communication with each other. The discharge oil passage (32) extends linearly at an inclination relative to a radial direction extending from a center of the oil pump (30), and the cooler inflow oil passage (33) is branched from the discharge oil passage (32) in a vicinity of a discharge port of the oil pump (30), at an inclination relative to an extension direction of the discharge oil passage (32).
