摘要： A metal gasket capable of preventing the occurrence of cracks in a stopper while employing a wave-shaped stopper, improving the contact pressure balance around the bead to enhance the engine performance, and improving the durability of the stopper. The metal gasket is constituted by a gasket component sheet having an opening formed to face a combustion chamber, and the gasket component sheet is provided with a combustion chamber bead surrounding the opening. An inner circumference side stopper lower than the height of the combustion chamber bead is formed along the combustion chamber bead in a portion between the combustion chamber bead and the opening such that at least a section of each wave where stress amplitude is large becomes thin, a thin portion and a thick portion are arranged alternately in each wave, and the hardness of the thin portion is higher than that of the thick portion.

摘要： To provide a seal layer-transferred metal gasket that can effectively prevent degradation in seal performance due to the wearing and peeling of the coating layer. A head gasket 1 is interposed between a cylinder block 2 and a cylinder head 3. In the metal gasket 1, seal layers 20 and 21 made by laminating a separation layer, a coating layer and an adhesive layer in this order from the bead sheet side is formed at least on the surface of the bead sheet 10 facing the cylinder block 2 and the cylinder head 3, and, in a state where the head gasket 1 is interposed between the cylinder block 2 and the cylinder head 3 and the three objects are closely attached to each other, the adhesive layer is adhered to the seal target members, and at least some portions of the coating layer and adhesive layer are separated from the bead sheet 10 with a boundary at the separation layer and then transferred to the seal areas 4 and 5 of the cylinder block 2 and cylinder head 3.
