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.

Sandwich-molded guide for transmission device

A plastic movable guide is disclosed wherein a reinforcing plate for reinforcing a guide body is simplified in shape, permitting easy assembly and prevention of disengagement. The movable guide is constituted by a guide body and a reinforcing plate fitted into the guide body. The guide body has a slit which receives the reinforcing plate which has a pair of recesses. A pair of windows are formed in the guide body to register with the reinforcing plate recesses. Each window has a tongue piece having a face which projects angularly into the slit and terminates in a retaining portion. When the reinforcing plate is advanced into the slit, the retaining portions of the tongue pieces are deflected out of the slit and when the plate is seated, the retaining portions are engaged in the recesses and retain the plate in the guide body.
