Claims

[Scope of utility model registration request]

A recessed step is formed on the side edge of the hole on the surface of the first member of the first member and the second member that are arranged to face each other so as to align the respective holes. Then, by fitting the end of the third member disposed to be mounted in the hole into the recess and tightening the first member and second member, the first member and a joint structure in which the third member is held between the second member, a metal gasket having an opening approximately the same size as the hole between the opposing surfaces of the first member and the second member. A bead for pressing the end of the third member is formed along the periphery of the opening of the metal gasket, and the bead is arranged so that its opening is aligned with the hole. The first member and the second member are made up of a plurality of bead parts by partially cutting out appropriate places in the direction.
A metal gasket arrangement structure for a joint structure, wherein the bead portion is configured to press an end of the third member after the member is tightened.
