An iron plate material having a plate thickness of 0 to 1.6 t is used, which is heavy as a structural material and poor in workability. In addition, when mounting, a fixed or irregular gasket is inserted and mounted on the mounting surface of the oil pan baffle plate (3), but in the case of the regular gasket, the number of parts increases and there is a disadvantage in assembly workability. The fixed gasket has a drawback that it requires skill to assemble and it is difficult to obtain a uniform and stable sealing force.

ねないものとなる。Further, since the iron plate material having the plate thickness as described above has no cushioning effect on the oil that flows down, it is likely to collide strongly with the surface and generate bubbles in the oil, which bubbles have a serious function in the engine. It will result in a decrease in the performance and may even lose its performance.

And an oil pan baffle plate (3) having a plurality of flow-down openings (32), large openings (33) being cut at a plurality of locations on the oil pan baffle plate (3) made of the metal thin plate, A thin film (4) made of an elastic material is extended from the surface of the oil pan baffle plate (3) to the periphery of the large opening (32), and the downflow opening (32) is provided inside the thin film. .

さしめる。That is, as shown in FIG. 1, the oil pan baffle plate (3) according to the present invention has a thin metal plate as a core material and a plurality of large cutouts (33) formed in the metal plate. A thin film (4) made of an elastic material is extended around the periphery of the large opening (32) and a flow-down opening (32) is provided inside the thin opening (32). The structure is covered by the thin film (4).
In particular, since the entire portion of the downflow opening (32) having a high oil flow velocity is covered with the elastic thin film (4), a strong buffering effect is provided against the oil scattered.
