Zusammenfassung: | The purpose of the present invention is to provide a metal gasket whereby sealing properties can be improved as a result of being capable of sufficiently compressing a full bead even if an elastic coating is formed along the full bead. In a gasket having formed on a metal substrate (10) a full bead (13) having a mountain-shaped protruding surface formed on one side thereof in the thickness direction and a valley-shaped recessed surface formed on the other side in the thickness direction, an elastic coating (20) is formed along the entirety of the protruding surface of the full bead (13) and the elastic coating (20) is formed on the recessed surface of the full bead (13), except for on a slit-shaped elastic coating-free section (14) along a bottom section (13a) of the recessed surface.
本发明的目的是提供种如下的金属垫片:沿着全凸缘形成弹性包覆膜,也能够充分压缩全凸缘,进而提高密封性能。在金属垫片的金属制基板(10)上形成全凸缘(13)所述全凸缘(13)在全凸缘(13)在厚度方向侧形成山形的凸面,在厚度方向的另侧形成谷形的凹面,在全凸缘(13)的整个凸面上形成弹性包覆膜(20),同时在全凸缘(13)的凹面上,保留沿着该凹面的底部(13a)的狭缝形的弹性包覆膜非涂敷部(14),进而形成弹性包覆膜(20)。 |
