Abstract
A metal laminate gasket of the invention is formed of first and second metal plates and an annular plate. The first metal plate has a base portion, a curved portion extending from the base portion to define a first opening corresponding to a hole of the engine to be sealed, and a flange extending from the curved portion and situated over the base portion. The annular plate is situated between the flange and the base portion and has the width at least partly shorter than that of the flange. The second metal plate is situated over the first metal plate at a side where the flange is located. The second metal plate has a second opening at least partly smaller than an outer diameter of the flange, and an edge portion around the second opening. The edge portion of the second plate is at least partly retained between the flange and the base portion. Thus, the first and second metal plates are assembled together with the annular plate.
