Abstract
A guide for as transmission device such as a chain or belt, is injection molded using a sandwich-molding process. The sandwhich-molded guide comprises a slide rail on which a chain or belt slides, and a rail supporting member intergrally provided along with the slide rail. The slide rail is composed of a material the principle component of which is first polymeric material having wear resistance and heat resistance, and the rail supporting member is composed of a material the principle component of which is a second polymeric material having higher strength than the material having the first polymeric material as its principle component. The slide rail and the rail supporting member are intimately joined to each other by injection molding using the sandwhich molding process.
