<p>A metal laminate gasket (10) for an internal combustion engine is formed of first, second and third metal plates (11, 13, 12). The first metal plate (11) includes a base portion (11a), a curved portion (11b) extending from the base portion to define a hole for a cylinder bore (Hc), and a flange (11c) extending from the curved portion and disposed under the base portion. The flange has a plurality of wide flange portions (11c1) and narrow flange portions (11c2) alternately arranged to each other such that the wide flange portions are located near bolt holes (Hb) arranged around the cylinder bore to support high tightening pressures applied thereto. The second plate (13) is situated under the base portion, and has a first bead (13c) formed around the cylinder bore and disposed between the base portion and the flange. The third plate (12) is situated between the base portion and the second metal plate, and is located outside the flange. The tightening pressures by bolts are supported by the wide and narrow flange portions to securely seal around the cylinder bore. <IMAGE></p> |
