Abstract
In a spherical annular seal member, a spherical annular base memberis constructed so as to be provided with structural integrity as a heat-resistant materialand a reinforcing memberare compressed to each other and intertwined with each other. In an outer layer, the heat-resistant material, a sintered solid lubricant constituted by a lubricating composition, and the reinforcing membermade from a metal wire net are compressed such that the sintered solid lubricant and the heat-resistant materialare filled in meshes of the metal wire net of the reinforcing member, and the solid lubricant, the heat-resistant material, and the reinforcing memberare integrated in mixed form, an outer surfaceof that outer layerbeing thus formed into a smooth surfacein which a surfaceconstituted by the reinforcing memberand a surfaceconstituted by the sintered solid lubricant are present in mixed form.
