Abstract

A heat-resistant shift member is disclosed which comprises (i) a fundamental body having substantially a desired configuration and formed of one or more of compressed heat-resistant materials such as expanded graphite with entangled wires being firmly embedded therein, and (ii) a shifting surface layer member integrally covering the shifting surface of the fundamental body which is formed of other compressed sheet-like heat-resistant materials such as asbestos, a heat-resistant sheet material made of fibers of asbestos, etc. laid thereon, one or more of powdered solid lubricant compounds such as metallic sulphide laid on the outer surface of the heat-resistant sheet material, polytetrafluoroethylene resin adhered to the outer surface of the powdered solid lubricant compound so as to partly penetrate into the porous surface thereof and partly form a coating thereon, and the metallic wires made of fine stainless steel wires to enclose the heat-resistant sheet material, the solid lubricant compounds and the polytetrafluoroethylene resin therein, whereby the wires of the fundamental body and the shifting surface layer are partially entangled with each other so that the solid lubricant …
