This spherical band-shaped sealing body (38) is a spherical band-shaped sealing body that is used for an exhaust pipe joint, and comprises: a spherical band-shaped base body (36) defined by a cylindrical inner surface (32), a partially convex spherical surface (33), and annular end surfaces (34, 35) each on the large-diameter side and the small-diameter side of the partially convex spherical surface (33); and an outer layer (37) formed integrally with the partially convex spherical surface (33) of the spherical band-shaped base body (36). The spherical band-shaped base body (36) comprises: a reinforcement material made of a metal wire netting (5); and a heat-resistant material that fills the meshes in the metal wire netting (5) of the reinforcement material, is intermingled and integrated with the reinforcement material, and includes expanded graphite which has been compressed. In the outer layer (37), the reinforcement material, the heat-resistant material, and a solid lubricant are intermingled and integrated together. |
