A plastic movable guide for a belt or chain transmission has a plunger-engaging portion for contact with the plunger of a tensioner at a location remote from its pivot axis. A reinforcing plate is located in a slot in a resin guide body, and is slightly recessed at the location of the plunger-engaging portion so that it does not protrude from the slot opening and is not contacted by the plunger of the tensioner. Superior quietness of operation, ease of assembly, and reduction of production cost are achieved.
