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 first sealing device around a first hole to be sealed, and an embossed portion between the first sealing device and a base portion of the first plate. The second plate has a second hole larger than the first sealing device, and a second sealing device around the second hole. When the first and second plates are assembled, the second plate does not pile the first sealing device. The gasket is securely sealed by the combination of the first and second sealing devices and the embossed portion.
