ABSTRACT:
A metal gasket of the invention is used for an internal combustion engine formed of a cylinder head and a cylinder block. The gasket is basically formed of one metal plate, and includes a plurality of cylinder bores arranged in a longitudinal direction of the gasket, and a plurality of bolt holes arranged to surround the cylinder bores. Edge support beads are formed on the plate around the cylinder bores located at the lateral side portions to substantially completely support tightening pressure of the bolts applied to the lateral side portions. Thus, deformation of the cylinder head is prevented, and substantially equal tightening pressure can be formed around the entire cylinder bores.
