Abstract: A sealing-equipped oil pan includes a gasket and an oil pan having a bottom portion and a peripheral wall for storing oil, and a ring-shaped rim portion located at an end of the peripheral wall and provided with the gasket, and is fastened to a target device with the gasket interposed between the rim portion and the target device. The gasket has a projection projecting from a sealing surface configured to come into contact with the target device for sealing. The peripheral wall of the oil pan has a base portion projecting from the rim portion and supporting the projection of the gasket. The base portion supports the projection of the gasket to prevent the gasket from tilting with respect to the rim portion, thereby preventing protrusion of the gasket.
