Abstract
A low-noise chain preventing a roller or a bushing from contacting a bottom portion of a sprocket thus reducing impact noise. The low-noise chain includes pairs of inner link plates and pairs of outer link plates alternately lined up with each other, each of the link plates having two insertion holes; connecting pins inserted into the insertion holes of the link plates to couple the inner and the outer link plate; and bushing or rollers disposed around the connecting pin. The roller or bushing has a substantially triangular configuration in transverse cross section and has three intermeshing surfaces on its outer circumference.
