ABSTRACT:
A sliding contact 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 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. Raised ribs, for sandwiching the reinforcing plate, are disposed on opposed inner surfaces of the walls, and are oriented in the direction of insertion of the reinforcing plate into the slot. The guide suppresses shock noises due to wobbling of the guide during operation, and molding and assembly of the guide are enhanced.
