Abstract
A heat-resistant shift member is disclosed which comprises 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 a shifting surface layer member integrally covering the shifting surface of the fundamental body which is formed of one or more of compressed other heat-resistant materials, such as asbestos as well as one or more of powdered solid lubricant compounds such as metallic sulphide with entangled other metal wires made of copper alloy being firmly embedded therein, whereby both of the metal wires are also partially entangled with each other. There is also disclosed a method for manufacturing the same.
