An oil pan (2) fixed on an engine mounted on a vehicle with an inclination angle has a first baffle plate (4), a portion of which is horizontally disposed, in the inside of the oil pan, a second baffle plate (5) disposed vertically between the first baffle plate (4) and the bottom of the oil pan (2)

An oil pan (2) fixed on an engine mounted on a vehicle with an inclination angle has a first baffle plate (4), a portion of which is horizontally disposed, in the inside of the oil pan, a second baffle plate (5) disposed vertically between the first baffle plate (4) and the bottom of the oil pan (2) such that said second baffle plate (5) partitions the space into two compartments, and an oil passageway between the two compartments. Since the oil passage way reduces mixed air bubbles in the oil when the oil flows through the passageway, either compartment has less mixed air bubbles such that the oil surface levels in the two compartments may be equalized and that the aeration may be reduced.
