A monolayer metal gasket is disclosed, which may be kept against deformation around a bolt hole(4) and further made stable in sealing stress around a gas hole(3) between mating surfaces(8,9) of confronting components(25,26). A first extra thickness(10) around the gas hole(3) is provided by turning back a part of a metallic sheet on a major flat(2) of the metallic sheet, with leaving a space(13) open between them to form a folded construction(12) having elasticity. A second extra thickness(15) around a bolt hole(4) is a closely layered construction of nearly rigid body little to be deformed. When the monolayer metal gasket is squeezed between the mating surfaces(8,9) of the confronting components(25,26), a clearance between the mating surfaces(8,9) may be regulated to a preselected distance by virtue of the second extra thickness(15) that is little to be deformed. <IMAGE> |
