A seal structure is provided using a metal gasket, the structure substantially preventing formation of a gap that would allow salt water to collect between the metal gasket and a casing, suppressing corrosion of the casing due to the collection of salt water and allowing long-term maintenance of the seal function. To achieve this purpose, a metal gasket is provided arranged between a pair of casings. The metal gasket is provided with a bead on the inner circumference of a planar circumference part and a bent part on the outer circumference. When the metal gasket is compressed between the pair of casings, the bead elastically deforms so that the height of the bead is reduced and the outer circumference part elastically deforms accordingly, causing the outer edge of the circumference part to contact one of the casings. This prevents formation of a gap that would allow salt water to collect between the casing and the outer circumference part. The bend-processed part contacts the other casing, providing a structure preventing formation of a gap that would allow salt water to collect between the other casing and the outer circumference part. |
