VEHICLE DRIVING APPARATUS

摘要

A mechanical oil pump (60), an electric oil pump (70), and a strainer (80) are disposed inside a transmission case (6). As a suction oil passage that returns an excess hydraulic pressure in a hydraulic control device (90) to the mechanical oil pump (60), a common oil passage (b1) extending from the hydraulic control device (90), a branch point (B), a first oil passage (b2) extending from the branch point (B) to the mechanical oil pump (60), and a second oil passage (b3) extending from the branch point (B) to the electric oil pump (70) are formed in the transmission case (6). A meeting point (C) where an inlet oil passage (a1) for suctioning oil via the strainer (80) and the first oil passage (b2) of the suction oil passage meet is formed inside a pump body of the mechanical oil pump (60). Accordingly, the suction oil passage of the mechanical oil pump (60) and an inlet oil passage of the electric oil pump (70) have a portion in common.
