Abstract
A synthetic resin 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 integrally molded 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. A convex pressing member, integrally molded with one of the walls protrudes into the slot through a partially cut-away portion of the wall and exerts a resilient pressing force on the reinforcing plate. The guide suppresses shock noises due to wobbling of the guide during operation. Increased molding tolerances are made possible, and higher productivity in the assembly of the guide is achieved.
Claims8
A synthetic resin guide for a flexible transmission medium comprising an elongated synthetic resin guide body, said guide body including a shoe extending along the longitudinal direction of the guide body, said shoe having a front surface arranged to contact a transmission medium, and a back side, and a plate-receiving portion provided on said back side of the shoe and integrally molded as a unit with said shoe, the plate-receiving portion also extending along the longitudinal direction of the guide body and comprising a pair of opposed walls extending along the longitudinal direction of the guide body and defining a slot between them, and a reinforcing plate fitted in said slot, between said opposed walls, wherein the improvement comprises a convex pressing member integrally molded as a unit with one of said walls, said pressing member protruding into said slot through an opening formed in said one of said walls, and resiliently pressing against said reinforcing plate.
