Gasket

Abstract

A gasket is formed by extrusion and easily fastened into a groove which can be easily formed by presswork. A gasket is configured to seal a gap between a first member that has a sectionally curved groove and a second member. The gasket includes a rubber-like elastic base and at least two pairs of rubber-like elastic fins. The base can be inserted into the groove, and has a height allowing the base to be compressed when the first member and second member are coupled to each other. The fins protrude at different heights from the both side surfaces of the base, and can elastically deform in a direction opposite to an insertion direction when the base is inserted into the groove so that the fins contact the side walls of the groove. The base and the fins are integrally formed with each other as one unitary member by extrusion.
