PROBLEM TO BE SOLVED: To facilitate mounting/demounting of a gasket, by constituting a gasket assembly by a substantially cylindrical sleeve provided with a slit extended between both ends and a plurality of slots, and a metal-made gasket provided with a plurality of lug part loosely inserted to the slot of this sleeve in a peripheral edge. SOLUTION: A gasket 10 is integrally molded by a metal-made material displaying a good seal characteristic so as to have opposed first/second seal surfaces and a circular center opening part 16, and in the periphery of this material, a pair of lug parts 20, 22 protruded to the outside are provided in a position opposed in a diametric direction. On the other hand, a substantially cylindrical sleeve 24 is formed of an elastic metal material, and this sleeve is formed with a continuous slit 29 extended in a vertical direction and a pair of slots 30, 32 in a position opposed to a diametric direction. A gasket assembly is constituted by mounting the lug parts 20, 22 fitted of the gasket 10 to these slots 30, 32. Here, mounting of the sleeve 24 is performed by diametrically spreading it. |
