    • A metal gasket is described which has a structure with no beads so that the need for dies used for molding is eliminated, thereby facilitating the processing of the gasket and achieving good cost performance, and which is excellent in sealing ability. The metal gasket comprises (i) an elastic metal plate having a base and folded-back portions each of which is formed so as to create a clearance together with the base and disposed so as to extend around a bore hole and (ii) a metal plate which is thicker than the elastic metal plate and has lower level portions each of which is located at a position closed to each bore hole, and the elastic metal plate and the metal plate are laminated such that each folded-back portion of the elastic metal plate faces the lower level portion of the metal plate.
    • 描述了一种金属垫圈,其具有不具有珠的结构,从而消除了用于模制的模具的需要,从而有助于垫圈的加工并实现良好的成本性能,并且密封性能优异。 金属垫片包括(i)弹性金属板,其具有基部和折回部分,每个弹性金属板形成为与基部一起形成间隙并且设置成围绕钻孔延伸,以及(ii)金属 该板比弹性金属板厚,并且具有较低的水平部分,每个部分位于与每个钻孔相邻的位置处,并且弹性金属板和金属板被层压,使得弹性金属的每个折回部分 板面向金属板的下部。
