Application No. 09/163,013
The invention relates to “a metal gasket to be installed
between the cylinder block and cylinder head of an engine”
(specification, page 1). Representative claim 14 reads as
follows:
14. A metal gasket comprising at least a first gasket-
constituting plate composed of an elastic metal plate having
an opening corresponding to the cylinder hole of the engine,
said gasket constituting plate including:
an annular stopper formed by folding back the peripheral
portion of said first gasket-constituting plate on an annular
pressure receiver portion of said first gasket-constituting
plate around the periphery of said opening, and
an annular bead formed in said first gasket-constituting
plate along the outer periphery of the stopper, said bead
projecting toward the side of said first gasket-constituting
plate on which the stopper is formed, wherein an inner
periphery of said bead functions as a stepped part to prevent
an overall deformation of said first gasket-constituting
plate,
wherein a raised spacer layer is formed by pattern
printing with a heat-resistant, compression-resistant material
between said stopper and said annular pressure receiver
portion of said gasket-constituting plate opposite said
stopper, and
wherein said heat-resistant compression-resistant
material adheres to said first gasket-constituting plate.
