れが起こり耐食性に問題がある。2. Description of the Related Art Noise sources of gasoline engines such as automobiles and outdoor generators, diesel engines and other internal combustion engines are mainly oil pans. For this reason, in an oil pan of a noise-reduction type internal combustion engine, a resin sandwich type damping steel plate with a resin intermediate layer interposed between the skin steel plates to enhance the damping effect is used to form the oil pan main body. Spot welding is used between the connecting piece of the steel reinforcing material placed inside and the oil pan main body.However, in this type of conventional oil pan, the oil pan main body is composed of both sides in consideration of corrosion resistance. Since the skin steel plates are both resin sandwich type vibration damping steel plates that are zinc-iron alloy plated steel plates,
There is a problem in corrosion resistance due to oil leakage from the welded portion of the main body of the oil pan with the connecting piece.

A reinforcing member 15 made of a steel plate, in which a connecting piece part 16 is formed in the bottom part and both side parts inside an oil pan main body 11 made of a resin sandwich type damping steel plate integrally interposed between them.
It is usual that each connecting piece portion 16 and the oil pan main body 11 are arranged at a plurality of welding spots 17 and 17, but the skin steel plates 12 and 14 are both zinc-iron alloy plated steel plate resin sandwiches. Looking at the cross section of the welded portion of the conventional oil pan using the vibration damping steel plate of the mold, a void 19 is generated in the nugget 18 as shown in FIG. If the oil continues to be circulated at high temperature and high pressure, engine oil may enter the space 19 and flow out.

The reason why the voids 19 are generated inside 8 is considered as follows. That is, of the zinc-iron alloy plated steel sheets that are the skin steel sheets 12 and 14, most of the zinc in the plating layer of the inner skin steel sheet 12 that is the inner surface of the oil pan main body 11 is 1300 ° C. or more immediately below the electrode during spot welding. Is discharged to the outside of the molten metal, but a part remains in this high temperature molten metal. Then, the zinc left in the high temperature molten metal becomes a gas because the melting point is 426 ° C. and the evaporation temperature is 900 ° C., which is gathered in the central part where the molten metal is slow to cool during the cooling process and heats up during solidification. Space 1 in the nugget 18 due to contraction
This is because 9 is generated.

Although the cold-rolled steel sheet is poorer in corrosion resistance than the zinc-based alloy-plated steel sheet, the inner surface 2 of the oil pan main body 1 made of the cold-rolled steel sheet does not corrode and easily corrodes because engine oil is put therein. Since the outer skin 4 is a zinc-iron alloy plated steel sheet having excellent corrosion resistance as in the conventional case, it can be durable for a long period of time.

与するところ極めて大きいものがある。As is apparent from the above description, the present invention is as follows.
An oil pan mainly made of a resin sandwich type damping steel plate consisting of an inner skin made of cold-rolled steel sheet, a resin intermediate layer and an outer skin made of zinc-iron alloy plated steel sheet. Since it is spot welded against the inner skin, the damping effect of the resin intermediate layer has an effect on noise suppression, and there is no gap in the nugget part of the welding spot, and oil leaks from the nugget part. There is no danger of it becoming more durable. In addition, by using an inexpensive cold-rolled steel sheet for the inner skin, there is an advantage that it can be provided at a lower cost than a conventional resin sandwich type vibration-damping steel sheet for oil pans in which both skin steel sheets are zinc-iron alloy plated steel sheets. Therefore, the present invention contributes to the industry as a solution to the problems of the conventional oil pan for an internal combustion engine, and is extremely significant.
