Abstract
An oil pan is disposed in a lower part of an internal combustion engine and has an oil pan body divided, with respect to a vertical direction, into oil pan elements having bottom walls respectively of different depths. A baffle plate divides the interior of the oil pan body into a plurality of spaces at the boundary of adjacent ones of the bottom walls to regulate the flow of oil between the adjacent ones of spaces. The baffle plate is divided with respect to a vertical direction into a plurality of baffle plate elements. The baffle plate elements are formed integrally with the oil pan elements, respectively. The oil pan for an internal combustion engine can be manufactured by reduced time and reduced labor at a low manufacturing cost.
