Abstract
A rocker-joint silent chain in which the pin insertion holes for each link have rocker-joint connecting pin means extending therethrough. Each pin insertion hole has two opposed, spaced-apart surfaces each having the cross-section form of arcs of uniform radius. The centers of curvature of said two surfaces are offset from one another so that they define an arcuate, but noncircular, cavity which is effective to wedge said connecting pin in load-transmitting relationship to its associated link when the chain is driven.
