<p>A metal laminate gasket (G) for an internal combustion engine is formed of a first metal plate (10), a second metal plate (11) situated under the first metal plate (10), and a plurality of annular plates (12). The first metal plate (10) includes a base portion (10a), a plurality of curved portions (10b) extending from the base portion (10a) to define first hol es (Hc), and a plurality of flanges (12) extending from the curved portions (10b) to be disposed over the base portion (10a). Each annular plate (12) is situated between each flange (10c) and the base portion (10a), and has at least one flat section and at least one partial bead section (12a) disposed at an intermediate portion between the first holes (Hc). The partial bead (12a) does not extend throughout an entire length of the annular plate (12). Therefore, when the gasket (G) is tightened, the surface pressure at the intermediate portion can be increased to securely seal thereat. In case the rigidity of a cylinder head is not strong, the gasket (G) is especially useful. <IMAGE></p> |
