In a sandwich molded guide for an endless, flexible, transmission medium such as a silent chain or roller chain, a slide rail and a rail support are sandwich-molded. The slide rail and the rail support are integrally molded from a high strength first polymer resin and the entire outer surface of the integrally molded structure is covered with a wear-resistant second polymer resin. A lightweight and inexpensive sandwich-molded guide, having excellent mechanical strength and wear resistance, can be easily molded in a single mold in a short molding cycle time, and can be readily recycled.
