A silent chain has a plurality of interconnected plates adapted for operative engagement with toothed surfaces of a sprocket. Each of the plates has flank surface portions and crotch surface portions, with the crotch surface portions having protruding portions. The protruding portions of the crotch surface portions make contact with the toothed surfaces of the sprocket at the beginning of engagement of each plate with the sprocket and are spaced away from the toothed surfaces of the sprocket at least during engagement of the flank surface portions with toothed surfaces of the sprocket.
