Abstract
A laminated gasket is provided, which ensures desired bore sealing surface pressures on the side of a cylinder head and on the side of a cylinder block, which is excellent in sealing ability and durability preferably by virtue of its double sealing function and which has a comparatively simple structure. This gasket has a core plate and elastic plates laminated to both surfaces of the core plate. The core plate has thin-walled portions each surrounding a bore opening and a thick-walled portion extending outwardly from each thin-walled portion. The elastic plates respectively have folded-back portions each of which is formed so as to create, together with a base portion, a clearance around its associated bore opening.
