In a cylindrical gasket 23, a heat-resistant material 1 made from expanded graphite and a reinforcing member 2 made from a metal wire net are provided with structural integrity by being compressed and intertwined with each other. A cylindrical inner peripheral surface 19, a cylindrical outer peripheral surface 20, and axial annular end faces 21 and 22 which are exposed on the cylindrical gasket 23 are each formed by a surface where a surface constituted of the heat-resistant material 1 and a surface constituted of the reinforcing member 2 are present in mixed form, and in the cylindrical gasket 23, the density of the heat-resistant material 1 is in the range of 1.21 to 1.58 Mg/m 3 , and the mass of the reinforcing member 2 occupies 50 to 80% of the total mass of the cylindrical gasket 23. |
