Abstract: A metal plate of the invention is used for a metal gasket. The metal plate comprises a base plate, at least one first bead to surround an area to be sealed, and at least one second bead extending from the first bead. An intersecting portion is formed between the first and second beads. The intersecting portion is provided with a depression extending from a side of a non-high pressure area toward an inside of the intersecting portion to reduce the size of the intersecting portion. As a result, the intersecting portion of the first and second beads can provide surface pressure at least substantially equal to the rest of the portions of the first and second beads without affecting the sealing ability at a high pressure area when the beads are compressed.

Abstract: A steel laminate gasket comprises a first plate having at least one first hole, a second plate situated adjacent to the first plate, and at least one depression formed either on the first plate or the second plate and extending toward the other. The second plate is provided with at least one second hole and a bead extending around the second hole. The bead extends substantially perpendicularly to a horizontal plate of the second plate toward the first plate to abut against the first plate. Height of the depression is substantially the same as or slightly less than that of the bead so that when the first and second plates are connected together by a spot welding at the depression, the first and second plates are maintained substantially parallel to each other.
