Any one of synthetic fiber of a polyester fiber, a polyvinyl alcohol fiber and an aramid fiber. Any one of woven fabric of vertical double-woven, lateral double-woven, vertical and lateral double-woven and triple-woven is used. Any one of synthetic resin of a resol type phenol resin, an epoxy resin and an unsaturated polyester resin is used. The sliding surface material is integrally joined to a cylinder inner surface of a cylindrical back plate comprising a cylinder body made of metal, and the sliding surface material is made to a slide layer. The cylindrical back plate comprises a steel pipe. Thickness of the slide layer is 1 mm.
