Abstract: PROBLEM TO BE SOLVED: To provide a seal structure using a metal gasket, which hardly generates such a clearance that salt water is pooled between the metal gasket and box bodies, suppresses the corrosion of the box bodies caused by the stay of the salt water, and maintains a seal function for a long period of time.SOLUTION: The metal gasket is arranged between a pair of the box bodies. The metal gasket has a bead at the internal peripheral side of a plane-shaped outer periphery and a bending processing part at the external peripheral side. When the metal gasket is pressure-sandwiched by the pair of box bodies, the bead is elastically deformed so as to lower its height, and the outer periphery is also elastically deformed with the elastic deformation of the bead. At this point, the outer periphery contacts with one box body at its external peripheral end, and by this, there is not formed such a clearance that the salt water is pooled between one box body and the outer periphery. Also, the bending processing part contacts with the other box body, and by this, the salt water is not pooled between the other box body and the outer periphery, thus providing the sealing structure of the metal gasket.
