Abstract: A steel laminate gasket for an internal combustion engine having at least one hole therein. The gasket comprises a first plate having at least one first hole and a first bead situated adjacent to the first hole to surround the same, and a second plate having at least one second hole and a second bead situated adjacent to the second hole to surround the same. The first and second holes correspond to the hole of the engine. The first and second beads include first and second top portions respectively. The distance from the second hole to the second top portion is different from the distance from the first hole to the first top portion. When the gasket is assembled, the first bead faces and abuts against the second bead so that the first and second top portions are located with a predetermined distance away from each other. Consequently, when the gasket is tightened, the first and second beads diagonally push with each other to provide secure sealing therebetween.

Abstract: A metal gasket of the invention comprises at least one metal plate including at least one fluid hole, a main bead extending around and adjacent to the fluid hole, and at least one auxiliary bead situated at an area away from a tightening device of the gasket. The auxiliary bead diverges from a part of the main bead, extends along the main bead and again merges to a part of the main bead. Therefore, an area adjacent the tightening device is sealed by the main bead, and the area away from the tightening device is sealed by the main bead and auxiliary bead to thereby provide equal sealability around the fluid hole when the gasket is tightened.
