Metal laminate gasket with surface pressure adjustment mechanism

A metal laminate gasket for an internal combustion engine having a hole to be sealed, consisting essentially of first and second metal plates and comprising:

• said first metal plate having a main potion extending substantially throughout an entire area of the gasket, a curved portion extending from the main portion to define a first hole corresponding to the hole of the engine, and a flange extending from the curved portion and situated under a part of the main portion,
• said second metal plate situated under the main portion and extending substantially throughout the entire area of the gasket, said second metal plate having a second hole in which said curved portion is located, an inner portion situated around the second hole and disposed on the flange, and an annular recess formed in the inner portion around the second hole to form a thin portion, said annular recess being located slightly away from the second hole and disposed on the flange, and
• at least one bead formed on the first metal plate to surround the hole of the engine to seal the same, said at least one bead extending toward the flange and directly facing the annular recess.
