Abstract

There is provided a silent chain that is reduced in weight and widthwise size by reducing the length of a short pin while preventing the occurrence of excessive stress concentration in the short pin of a rocker pin including a long pin and the short pin. The short pin of the rocker pin extends through all plates of the guide row and all plates of the non-guide row in the width direction. The short pin is provided with a first stopper, and a second stopper. A first end surface of the short pin is prevented from being positioned in a first adjacent pin hole by contact between the first stopper and the first contact portion, and a second end surface of the short pin is prevented from being positioned in a second adjacent pin hole by contact between the second stopper and the second contact portion.
