Abstract
A cylinder head gasket is formed by a metal substrate, and a supporting plate laminated on the metal substrate. The metal substrate and the supporting plate include cylinder bores, fluid holes, and a plurality of bolt holes. The metal substrate includes a sealing bead around the cylinder bore thereof to form a bore sealing portion. The cylinder bore of the supporting plate is greater than the sealing bead without laminating the sealing bead, so that a total plate thickness at the bore sealing portion is less than a laminated portion of the metal substrate and the supporting plate outside the bore sealing portion.
