Abstract
A metal gasket for sealing a three-component joint structure in which first and second joint members are disposed in confronting relation so as to align their respective holes with each other and in which an outer peripheral portion of a third joint member is fitted in a recess in the confronting surface of the first joint member. The metal gasket has an opening and is adapted to be placed between the first and second joint members so as to align the opening with the holes of the two joint members. The metal gasket also has, at a position near the opening, a stepped portion defined by first and second bends engageable with the first and second joint members, respectively, as the metal gasket is placed between the two joint members. As the first and second joint members are tightened so as to clamp the third member and the metal gasket, the stepped portion is deformed so as to bring the second bend to a position confronting the third joint member.
