摘要： A metal gasket for a cylinder head of an internal combustion engine comprises at least one narrow portion extending between cylinder bores of the cylinder head to be sealed by the gasket, and beads extending along circumferences of the cylinder bores. The adjacent beads extend in opposite directions with respect to the gasket, thereby enabling the adjacent beads to be smoothly and gently connected. Such smoothly connected beads prevent any cracks or permanent deformations in the proximity of the beads from occuring when the gasket is firmly clamped between the cylinder head and an engine body. Restoring faculty of the gasket is not lost after being clamped therebetween, so that the sealing capacity in the proximities of the beads is remarkably improved in comparison with the prior art.
