Abstract
An oil strainer includes a body member which includes a circumferential wall projecting in a first (downward) direction toward an oil pan, and a cover member covering an inside space surrounded by the circumferential wall, and including a suction hole to suck an oil from the oil pan. The body member further includes a communication hole opened into the inside space surrounded by the circumferential wall and adapted to lead to the inlet side of an oil pump, and a discharge hole opened into the inside spaces, and adapted to receive the oil discharged from a pressure regulating valve. The body member further includes a partition wall extending from the circumferential wall, and separating the communication hole and the discharge hole.
