Abstract
An engine gasket flattens the surface pressure occurring around holes, prevents the occurrence of impressions in and damage to a cylinder block and a cylinder head, and secures a stable sealing performance. This metal gasket has elastic metal plates and an intermediate metal plate interposed between these elastic metal plates. The elastic metal plates are provided with full beads along the circumferences of the holes so that the ridge portions of the full beads contact the intermediate metal plate. The intermediate plate has, on regions which are between the holes and full beads of the elastic metal plates, half beads extending toward the elastic metal plates. The elastic metal plates are folded back along the circumferences of the holes.
