る。An outer reinforcing plate 8 having a U-shaped cross section is attached to the outer side surface 2a of the shallow bottom portion 2. The outer reinforcing plate 8 is located below the straightening plate 6 on the bottom surface 2b of the oil pan shallow bottom portion. Has been extended to. A straightening plate reinforcing plate 9 having a U-shaped cross section is fixed to the side surface of the straightening plate 6, so that the plate material constituting the oil pan shallow bottom surface 2b is the external reinforcing plate 8.
And the straightening plate reinforcing plate 9 are sandwiched between them. In addition,
The rectifying plate reinforcing plate 9 is not always necessary depending on the shape of the rectifying plate 6, but the rectifying plate reinforcing plate 9 is reinforced by reinforcement when attached.
【００１６】このようにして、オイルパン浅底部２は、
側面２ａ及び底面２ｂが連続して補強された状態となっ
ているので極めて強固になっている。In this way, the shallow bottom 2 of the oil pan is
Since the side surface 2a and the bottom surface 2b are continuously reinforced, they are extremely strong.
