ABSTRACT:
A metal laminate gasket of the invention is formed of first and second metal plates laminating together. The first plate includes at least one first hole for receiving therein an engaging projection of an engine part, and a plurality of first engaging portions and first non-engaging portions alternately arranged to each other to define the first hole. The first engaging portions have first curved inner edges for forming a first imaginary hole with a diameter smaller than a diameter of the engaging projection. The second plate includes at least one second hole corresponding to and located above the first hole, and a plurality of second engaging portions and second non-engaging portions alternately arranged to each other to define the second hole. The second engaging portions have second curved inner edges for forming a second imaginary hole with a diameter smaller than the diameter of the engaging projection. When the gasket is placed on the engine part, the first and second engaging portions engage the engaging projection to prevent disengagement of the gasket from the engaging projection.
