Abstract
A silent chain is constituted by a number of articulately connected link plates each having an engagement surface for meshing engagement with teeth of a sprocket. The link plates are press-formed so that the engagement surface includes a smooth sheared surface. All of the link plates have respective sheared surfaces along not more than 60% of the thickness of the link plates. In order to reduce noises produced when the link plates mesh with the sprocket teeth, more than 50% of the link plates have respective sheared surfaces along 7 to 15% of the thickness of the link plates and are arranged randomly in the silent chain.
