Abstract
A chain guide for automobile camshaft drive chains and the like comprises a lever arm having a mounting hole for receiving a pivot shaft, and a synthetic resin chain-engaging shoe having a pair of tongues, which embrace the arm on both sides, and which have holes aligned with the mounting hole of the arm, so that the shoe cannot disengage the arm when the shoe and arm are mounted on the pivot shaft. The tongues have convex portions which engage concave contoured steps on the sides of the arm with a snap fit, so that the shoe is held in proper relationship to the arm before mounting on the pivot shaft.
