ABSTRACT:
A synthetic resin guide for a chain, or other flexible transmission medium comprises a synthetic resin guide body having a shoe on which the transmission medium slides, and a slotted, plate-receiving portion integrally molded on the back side of the shoe for receiving a reinforcing plate. The plate-receiving portion is composed of a pair of opposed, longitudinally extending, slot-defining walls. A convex pressing member, integrally molded with one of the walls protrudes into the slot through a partially cut-away portion of the wall and exerts a resilient pressing force on the reinforcing plate. The guide suppresses shock noises due to wobbling of the guide during operation. Increased molding tolerances are made possible, and higher productivity in the assembly of the guide is achieved.
