An oil pan (10a) provided with a structure which appropriately minimizes contact in the oil pan (10a) between oil (L) and gas. The oil pan (10a) includes the oil (L) contained in the oil pan, and a film (S1) for covering the surface (F) of the oil (L) so as to isolate the oil (L) from the gas above the oil. The film (S1) can float by buoyancy which the film receives in the oil (L). The film (S1) can consist of liquid. The film can also be constructed from a film member. |
