摘要:
A mechanical oil pump, an electric oil pump, and a strainer are disposed inside a transmission case. As a suction oil passage that returns an excess hydraulic pressure in a hydraulic control device to the mechanical oil pump, a common oil passage extending from the hydraulic control device, a branch point, a first oil passage extending from the branch point to the mechanical oil pump, and a second oil passage extending from the branch point to the electric oil pump are formed in the transmission case. A meeting point where an inlet oil passage for suctioning oil via the strainer and the first oil passage of the suction oil passage meet is formed inside a pump body of the mechanical oil pump. Accordingly, the suction oil passage of the mechanical oil pump and an inlet oil passage of the electric oil pump have a portion in common.
