Abstract

The present invention relates to a gasket including an annular body having plural rows of protrusions protruding from top and bottom surfaces by a first desired height in a circumferential direction, so that the protrusions formed in a shape of a fish bone are bent in an axial direction to have a desired curvature; a first sealing portion formed along an inner circumferential surface of the body and having a C-shaped cross section; and a first core spring of a disc coil positioned in the first sealing portion. Air tightness is guaranteed by the fish born-shaped protrusions. Since the protrusions are bent at a desired angle in an axial direction, the air tightness is guaranteed even under the influence of turbulence. Since the first core spring leads to increase a restoring force of the gasket and yield ability, a lifespan of the gasket is extended. Also, since the first core spring does not need for a separate jacket, and the first sealing portion is formed on the body, the gasket is easily fabricated.
