摘要：
A metal gasket (G) is formed of a metal plate (15) having a base portion (15a) extending substantially throughout an entire area of the gasket and a hole (Hc) in the metal plate. A main bead (16) is formed in the plate to surround the hole, and has a first head portion (16a) located above the base portion. Two auxiliary beads (17) are formed in the plate to sandwich the main bead therebetween. Each auxiliary bead (17) has a second head portion (17a) located below the base portion and a height (HB) less than a height (HA) of the main bead (16). When the gasket is tightened, the surface pressures are concentrated at the head portions to secure seal around the hole and to provide balanced surface pressures.
