ABSTRACT:
A steel laminate gasket of the invention is installed in an internal combustion engine having at least one hole therein. The gasket comprises a first metal plate, and a second metal plate situated under the first metal plate. The first plate includes a sealing device around a first hole to be sealed, and a wide bead situated between the sealing device and a base portion of the first plate. The second plate has a second hole larger than the sealing device, and a support bead around the second hole. When the first and second plates are assembled, the second plate does not pile the sealing device, while the support bead is located under the wide bead. When the gasket is tightened, the sealing device seals around the hole, and also, the support bead supports the wide bead to widely seal around the hole.
