Abstract
A metal laminate gasket for an internal combustion engine is formed of a first metal plate and one of plate combinations. The first metal plate includes a base portion, a curved portion to define a first hole, and a flange located under the base portion. Each plate combination includes an annular shim disposed between the flange and the base portion, and a second metal plate disposed under the base portion without laminating the annular shim and the flange. The thickness of the second metal plate is greater than the thickness of the annular shim and less than the total thicknesses of the annular shim and the flange. Each plate combination has the annular shim and the second metal plate with different thicknesses while keeping a difference in thickness between the annular shim and the second metal plate constant. Thus, the gaskets having the same grades with different thicknesses are formed by changing the plate combinations.
