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, 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. The gasket has 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. Edge support shims are installed between the plates 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.
