Abstract
A silent chain includes double rocker joint pins articulately connecting together adjacent links of the chain. The double rocker joint pins are each composed of a longer pin and a shorter pin. The longer pin has a cross-sectional shape different from that of the shorter pin, and the thickness of the longer pin as measured in a direction parallel to a chain pitch line is made greater than the corresponding thickness of the shorter pin. By thus designing the longer pin relative to the shorter pin, the longer pin has a large mechanical strength sufficient to withstand not only an impact force applied when the longer pin is swaged or riveted at opposite ends thereof, but also a shear force and a bending force applied at one time to opposite end portions of the longer pin during power-transmitting operation of the chain.
