Abstract
In a silent chain composed of interleaved rows of link plates held by connecting pins secured to guide plates disposed along the sides of the chain, the guide plates are formed with protrusions, and are deformed so that they exert a spring action on the rows of link plates through the protrusions, pressing the link plates against one another to increase the frictional contact between the link plates, and thereby reduce vibration and vibration noise.
