ABSTRACT:
A thick-walled, narrow-width oil strainer positioned in a space formed between the contact surfaces of the transaxle casing and transaxle housing of an automatic transmission is disclosed. Both the upper body and lower bodies of the oil strainer are constructed with an angled cross section to provide a deep suction section and a deep discharge section. A filter element is supported by being interposed between the peripheral edge sections and supporting bosses of the two bodies, and is slanted at a prescribed angle with respect to the suction section and the discharge section. The strainer is mounted with the right and left openings of the discharge section interposedly supported by the pump body and the transaxle casing, so that the oil discharged from the valve body is sucked directly into the pump through the suction section, and the oil in the oil sump is sucked into the pump through the filter element.
