Abstract
A plastic movable guide for a chain or other traveling transmission medium, comprises a guide body composed of a shoe and a slotted plate-receiving portion integrally molded as a unit from a resin, and a reinforcing plate inserted into the slot. A mounting hole adjacent one end of the guide body is aligned with a hole adjacent one end of the reinforcing plate. The diameter of the hole in the reinforcing plate is larger than the diameter of the mounting hole in the guide body, so that the inner periphery of the hole in the reinforcing plate does not extend inward past the edge of the mounting hole. The guide so configured exhibits excellent quietness and assembly efficiency and can be produced at a relatively low cost.
