Abstract
A spherical annular seal memberincludes a spherical annular base memberdefined by a cylindrical inner surface, a partially convex spherical surface, and an annular end facesand; and an outer layerformed integrally on the partially convex spherical surfaceof the spherical annular base member. The spherical annular base memberincludes a reinforcing membermade from a metal wire net and a heat-resistant materialfilling meshes of the metal wire net of the reinforcing memberand formed integrally with the reinforcing memberin mixed form. The outer layerincludes a base layerand a sliding layerconstituted of a lubricating composition and adherently formed integrally on the base layerat an outer layer intermediate surface, the base layerincluding a reinforcing membermade from a metal wire net and compressed and a heat-resistant materialfilling meshes of the metal wire net of the reinforcing memberand closely press bonded to the reinforcing member, the base layerbeing formed integrally with the partially convex spherical surface
