Abstract
A metal laminate 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 two metal plates laminated together. The gasket has a rectangular shape extending in a longitudinal direction, and two lateral side portions, each being defined between a lateral edge and a line linking centers of bolt holes located adjacent to the lateral edge. At least two edge support beads are integrally formed in at least one of the plates. The bead has a V shape opening toward the lateral edge. Thus, the lateral side portions are widely supported to thereby prevent deformation of the cylinder head and provide substantially equal tightening pressure around the entire cylinder bores.
