Abstract
A metal gasket is disclosed in which a sealing stress exerted on a deck-surface from any one of confronting bead plates is dispersed slantwise along the direction leaving its associated cylinder bore aperture so that the cylinder bores are protected from deformation owing to the high sealing stress occurring in the open-end portions of the cylinder bores. The bead plates have sealing beads confronting flanges of an first intermediate plates at their borderlines smaller radially of their associated cylinder bore apertures while confronting the first intermediate plate, less in thickness than the flanges, at their borderlines larger radially of their associated apertures. The sealing stress on the deck-surfaces of the cylinder block and cylinder liner due to deformation of the beads may be dispersed uniformly over the flanges to thereby reduce the influence of the sealing stress on the liner section of the cylinder liner.
