ルパン本体１の制振性能の劣化や強度の低下を招
来する問題があつた。 However, when the flange portion 3 is bent in this manner, shear stress is generated between the laminated steel plates 4a and 4b, and the steel plates 4a and 4b at the ends of the flange portion 3 tend to separate and open. Water, oil, etc. may infiltrate into the resin layer from the parts, causing extensive peeling between the steel plates 4a and 4b, or causing rust, leading to deterioration of the vibration damping performance and strength of the oil pan body 1. There was a problem.
［考案の目的］

Features.
［考案の実施例］
以下に本考案の一実施例を添付図面に基づいて
詳述する。[Embodiment of the invention] An embodiment of the invention will be described below in detail based on the accompanying drawings.
第３図において、１はオイルパン本体であり、

取付けられるようになつている。 In Fig. 3, 1 is the oil pan body;
The vibration damping steel plate 4 is press-molded by laminating two thin steel plates 4a and 4b with a resin layer 5 sandwiched therebetween. The peripheral edge of the oil pan body 1 is folded back outward to form a flange 3, which is attached to the lower part of the internal combustion engine body 2 by bolts 6.
そして、フランジ部３の端部３ａには第４図に
示す如くその周方向に沿つて鋼板４ａ，４ｂ相互

８によつてフランジ部端部３ａに形成された溝で
ある。 As shown in FIG. 4, the end 3a of the flange portion 3 is provided with a crimped seal portion 7 along the circumferential direction of which the steel plates 4a and 4b are crimped together.
This pressure seal portion 7 is formed by cold pressure welding, for example, a pair of upper and lower pressure rollers 9, 1 having a plurality of protrusions 8 on the outer periphery.
0, the end portion 3a of the flange portion 3 is pressed from the front and back between the rollers 9 and 10 while rotating the rollers 9 and 10. It is formed. Reference numeral 11 indicates a groove formed in the flange portion end portion 3a by the projection 8.
しかして、上記構造によれば、フランジ部３の
端部３ａに圧着シール部７が形成され、端部３ａ

共に耐久性の向上が図れる。 According to the above structure, the crimp seal part 7 is formed at the end 3a of the flange part 3, and the end 3a
Since the laminated steel plates 4a and 4b are interlocked with each other and come into close contact with each other, water from the end portion 3a to the inside of the resin layer 5,
Infiltration of oil etc. can be prevented. Therefore, peeling between the steel plates 4a and 4b and occurrence of internal rust can be prevented, so vibration damping performance can be maintained and durability can be improved.
また、鋼板４ａ，４ｂが互に密着して通電する
ようになるため、プロジエクシヨン溶接を行うに
際して鋼板４ａ，４ｂ間に形成していた通電用ス
ポツト部が不要になる。 Further, since the steel plates 4a and 4b are in close contact with each other and energized, the current supply spot formed between the steel plates 4a and 4b when performing projection welding becomes unnecessary.
尚、フランジ部３は第５図のイ，ロ，ハの順で
３回折曲げられることにより形成され、その端部

止することができる。 The flange portion 3 is formed by being bent three times in the order of A, B, and C in FIG. It is formed. In this case, if the bending angle θ of the second bending portion is set to 45° as shown in FIG. 6, the strain occurring between the inner and outer steel plates 4a and 4b can be suppressed to a small extent, and the occurrence of wrinkles at the end portion 3a can be suppressed. can be prevented.
尚、実施例では圧着シール部７を最終段階で形
成したが、予め制振鋼板４に圧着シール部７を形
成し、爾後プレス成型するようにしてもよい。 In the embodiment, the crimp seal portion 7 is formed at the final stage, but the crimp seal portion 7 may be formed in advance on the damping steel plate 4 and then press-molded.
