Abstract
A spherical annular seal member () has a seal body () in which a heat-resistant material () and a reinforcing member () made of a metal wire have been compressed to fill meshes of the metal wire net of the reinforcing member () with the heat-resistant material () such that the heat-resistant material () and the reinforcing member () are integrally formed in mixed form. The seal body () has a cylindrical inner peripheral surface () defining a through hole (); an outer peripheral surface () constituted by a partially convex spherical surface (); and annular end faces () respectively provided on a large-diameter side and a small-diameter side of the partially convex spherical surface (). In the seal body (), the reinforcing member () and the heat-resistant material () are respectively contained at a rate of 15 to 80 wt. % and at a rate of 20 to 85 wt. %. The heat-resistant material () in the seal body () has a density of 1.20 g/cmto 2.00 g/cm.
