Abstract
In a silent chain, cushion pads are provided in the inner flank regions of at least every second link row. These cushion pads restrict inward flexion of the chain and reduce vibration of the free span regions of the chain. The cushion pads can be individual pads each associated with a link plate, or elongated pads each associated with a row of link plates. In either case, side parts protruding toward the outside of the loop formed by the chain can also restrict outward flexion of the chain.
