Abstract
A silent chain includes guide washers to prevent bending of the connecting pins during prestressing. The chain has multiple link plates, each with a pair of teeth and pin apertures. The links are interleaved in the transverse and longitudinal directions and are connected pivotally by connecting pins. The connecting pin is composed of a joint pin that is arcuate in cross-section and a rocker pin, which is shorter than the joint pin and arcuate in cross-section. A guide washer is provided for each connecting pin. The guide washer has guide parts that extend on both sides of the teeth of the link plate and includes a pin aperture for fixing the end of the joint pin.
