Abstract
A cylinder head gasket is provided for an engine with low rigidity and a high maximum pressure. In the cylinder head gasket, it is possible to enhance the secondary sealing without greatly affecting the primary sealing. The cylinder head gasket is formed of a first metal plate with a first full bead under a folded portion around a cylinder bore, and a second metal plate with a second full bead around the first full bead. The second metal plate is made of a material with elasticity greater than that of the first metal plate, and is arranged with a gap relative to an outer edge of the folded portion so as not to overlap. The first full bead and the second full bead have top portions facing in opposite directions.
