ABSTRACT:
An oil pan for a vehicle engine is cast to have shallow and deepened bottom oil pan sections and an integral fitting flange to which a transmission case is attached. The fitting flange is formed with bosses for receiving bolts to tightly attach the oil pan to an engine block of the vehicle engine. First or outer reinforcing ribs extend along the center line of the bosses. Second or back reinforcing ribs are arranged correspondingly to the outer reinforcing ribs. Bolts pass through the bosses and tighten the oil pan to the bottom of the cylinder block of the vehicle engine.
