Abstract
A silent chain is provided in which a plurality of link plates of a certin configuration may have an identification indicator marked on a reference surface thereof at the time connecting pin inserting holes are punched into the link plates in order to ensure the link plates are properly directed in the same direction, are superposed on the connecting pins, and are constituted in a chain-like manner by the connecting pins so that meshing surfaces of the link plates mesh smoothly to prevent any meshing noise.
