In recent years, instead of such damping plates, damping steel plates have been developed that are made by interposing a resin layer between two steel plates. If an oil pan is made by press forming using such a damping steel plate, processing becomes very easy. However, delamination may occur at the cut edges of damping steel plates during press forming, and after long-term use, there is a risk that water may enter the delaminated areas from the outside and cause corrosion.

A bolt 6 inserted through the hole 4 is screwed into the crankcase 5 and fixed. In order to prevent water from entering the bolt holes 4 of the flange 3, the seat plate 20 is made of a metal plate 22 with rubber layers 21 baked on both sides, as shown in FIG.

が覆われる。 According to the present invention, for an oil pan made of a damping steel plate, the hanging edge 13 is formed by folding back the outer edge of the flange 3 which overlaps the lower end wall surface of the crankcase 5 downward, and the cut edge of this hanging edge 13 The edge is covered by a grommet 19 integral with the packing 18 and having a U-shaped cross section. In other words, the outer peripheral edge of the packing 18 is extended along the hanging edge 13, and the cut edge of the hanging edge 13 is covered by the grommet 19 formed by folding the end of the extended portion back into a U-shape.
