An oil pan for an internal combustion engine includes an outer shell made of metal plate an includes on at least a bottom surface of the outer shell and inner pan separate from the outer shell. The bottom of the oil pan includes a deep portion and a shallow portion and a baffle plate is disposed over the inner pan. The inner pan settles on the inner surface of the outer shell amidst the oil contained in the oil pan, thereby forming a layer of oil between the outer shell and the inner pan. Thus, oil flow is not impeded and vibration of the oil pan is significantly reduced. In addition, wall portions of the inner pan are made to be deformable so as not to cause strong impact to other portions of the oil pan structure or to engine components.
