Abstract
In a sliding contact guide for a chain, a guide body is composed of a shoe having a front surface on which the chain slides, and a plate-receiving portion provided on the back of the shoe. The shoe and plate-receiving portion are integrally molded from a synthetic resin. A reinforcing plate is inserted and fitted into a longitudinal slot in the plate-receiving and the sliding contact guide is attached to a frame by a pivot pin which extends through aligned mounting holes in the guide body and the reinforcing plate. Locking pieces formed in the plate-receiving portion, have tapered surfaces on their tips that engage locking holes in the plate and exert a biasing force on edges of the locking holes which urges the plate against the back of the shoe. The reinforcing plate and the guide body are reliably secured together and, even when the guide is vibrated, movement of the reinforcing plate in the slot of the guide body is prevented, so that low noise and long life are attained.
