Claims

[Claims for Utility Model Registration] 1. A bead substrate with inwardly directed beads formed in a contour shape along the periphery and outer periphery of parallel cylinder bore openings and other openings, and surface-treated on both sides, is used as an adjustment plate. A small protrusion 6 is formed along the surface of the adjustment plate 2 corresponding to the outside of the bead 4 at the periphery of the cylinder bore opening A of the bead base plate 3 on the cylinder head side.
A metal gasket characterized in that the gaskets are arranged side by side in an annular shape. 2. The metal gasket according to claim 1, wherein the height of the small protrusion 6 in the proximal portion 7 between the adjacent cylinder bore openings A, A is higher than the small protrusion 6 in the other annular portions.
