Abstract
A metallic gasket having a first seal line SLarranged in a manner to encircle the peripheral edge of an exhaust gas hole, a second seal line SLarranged along the outer peripheral edge of a base plate, and full beadsformed each in a convex cross-section by bending the base platealong both seal lines. Elastic sealing materialto, the height of which is substantially equal to the height of a convex portion of the beads, are fixed to the convex portion and a flat surface continuous to the convex portion. The elastic sealing material on the flat surface is so arranged as to cover up to the opening mouth position of the exhaust gas holeor a peripheral edge position of the base plateand, furthermore, elastic material partsare filled in a concave portion of the bead on the reverse side of the convex portion. This structure of the gasket leads to cost reduction and enables the gasket to maintain a stable sealing performance for a long period of time.
