    摘要: A metal gasket (G) for an internal combustion engine is basically formed of a main plate (11). The main plate includes a first hole (Hb') for constituting one of bolt holes, a second hole (Ho) corresponding to a fluid hole and situated adjacent to the first hole, and a full bead (13) having a first half bead (13a) and a second half bead (13b) situated outside the first half bead. The first half bead (13a) completely surrounds only the second hole (Ho), and the second half bead (13b) surrounds the first and second holes (Hb', Ho). Thus, a portion away from the first hole is surrounded by the first and second half beads to securely seal around the second hole. Also, the tightening pressure by the bolt can be supported with good balance.
