For the improvement on transmissional functions of roller chains, it is one of the most important matters to take measures for reduction of the own-weight of roller chains. From this point of view, in this report, we propose to take away the unnecessary parts of the pin-link plate stronger than the roller-link plate, and to reduce the own-weight of roller chains, as far as its maximum stresses increase to the maximum circumferential stresses produced at the eye-end parts of the roller-link plate. For the above purpose, two practical methods, i.e. reducing the plate-thickness and equeezing the form at the center of the pin-link plate, were examined by numerical calculations. Moreover, results of fatigue tests conducted on bicycle roller chains and standard roller chains for power transmission, which have each properly squeezed form at the center of the pin-link plates, indicate the appropriateness for squeezed forms of produced pin-link plates.
