Abstract
In the inner portion of a spherical annular seal member (55) extending from a cylindrical inner surface (52) to an outer surface (53) formed in the shape of a partially convex spherical surface, a heat-resistant sheet member (3) having a heat-resistant coating (2) on overall surfaces of a heat-resistant sheet and a reinforcing member (9) constituted by a metal wire net (8) are compressed and intertwined with each other, and are thus arranged to be provided with structural integrality. The outer surface (53) formed in the shape of the partially convex spherical surface is constituted by an exposed surface of an outer surface layer (56) formed of the heat-resistant coating (2), and the reinforcing member (9) constituted by the metal wire net (8) formed integrally with the outer surface layer (56) is disposed in the outer surface layer (56). The outer surface (53) formed in the shape of the partially convex spherical surface, where the outer surface layer (56) and the reinforcing member (9) constituted by the metal wire net (8) formed integrally with the outer surface layer (56) in mixed form are exposed, is formed into a smooth surface.
