ABSTRACT:
The oil pan includes an oil introducing portion that has an oil introducing plate. The oil introducing plate has an insertion hole for receiving a sucking portion of an oil strainer. The oil introducing plate extends from the periphery of the insertion hole toward a side wall of the oil pan. The oil returned from the first oil return passage is introduced to flow along the oil introducing plate via an oil falling hole formed in a baffle plate that is positioned at the bottom of a crank case of the internal combustion engine. The oil introducing portion further includes a plurality of inclined wall portions mounted on a bottom portion of the oil pan in the vicinity of the side wall of the oil pan in order to support the oil introducing plate. Opening portions are formed between the inclined wall portions and the bottom portion of the oil pan. The oil introducing plate of the oil introducing portion is located just below the oil falling hole formed in said baffle plate.
