ABSTRACT:
In a pivoted plastic movable guide for a chain or belt transmission, having a reinforcing plate disposed in a slot on a plate-receiving portion on a back side of the guide, a plunger-engaging part of the plate protrudes slightly from the opening of the slot for contact with the plunger of a tensioner. The plunger-receiving portion of the plate has a curved profile, preferably in the form of a convex or concave circular arc, which engages the plunger over a contact area which does not vary with a changing angle between the plunger and the guide. The edge of the reinforcing plate is also preferably in the form of a circular arc, or has beveled or rounded edges to avoid excessive wear due to load concentration.
