<p>A low-noise chain (1) preventing a roller (6) or a bush from contacting with a bottom portion of a sprocket (10) thus reducing impact noise. The low-noise chain includes pairs of inner link plates (2) and pairs of outer link plates (3) alternately lined up with each other, each of the link plates having two insertion holes (21, 31); connecting pins (5) inserted into the insertion holes of the link plates to couple the inner and outer link plates; and bushes or rollers (6) disposed around the connecting pin, whereby the roller (6) or bush has a substantially triangular configuration in transverse cross section and has three intermeshing surfaces (62) on its outer circumference. <IMAGE> <IMAGE></p> |
