整することを特徴とする金属ガスケツト。 A sub-plate is laminated on a substrate made of an elastic metal plate formed with a bead that surrounds the combustion chamber hole, and the edge of the sub-plate on the side of the combustion chamber hole is folded over and overlaid with the substrate in between, or the sub-plate is placed to surround the combustion chamber hole. A metal gasket in which a sub-plate is laminated between substrates made of elastic metal plates having beads, and another sub-plate is laminated on the sub-plate, or the edge on the combustion chamber hole side is folded back and polymerized by itself. The plate thickness at the edge of the combustion chamber hole side of either or both of the base plate or the sub-plate is decreased as it approaches the bolted part in accordance with the amount of gap between the deck surfaces that occurs when the gasket is bolted. Further, by making the thickness of the folded part substantially constant around the entire circumference of the combustion chamber hole and creating a gap between the folded part and the reduced plate thickness part,
A metal gasket characterized in that the folded portion follows the amount of bolt tightening of the metal gasket to finely adjust the amount of gap between the deck surfaces.
