Abstract
A metallic gasket includes two base plates and a subplate interposed between the base plates, and cylinder bore holes are formed respectively in the base plates and the subplate concentrically. Beads are respectively formed on the base plates circumferentially along a periphery of the cylinder bore hole. An inner edge of the subplate facing the cylinder bore hole is folded back to form a folded section having two layers, and a starting point of a substantially round-shaped folded end portion of the folded section of the subplate is positioned on a line perpendicular to a surface of the gasket, which line passes through ends of the base plates defining the cylinder bore hole, or the starting point of the folded end portion of the folded section of the subplate is positioned slightly at an inside towards the cylinder bore hole beyond the ends of the ends of the base plates. As a result, the folded end portion of the subplate protrudes beyond the ends of the base plates.
