In this report, the fatigue strengtn and impact strength of roller chain link-plates subjected to various conditions of heat treatment are shown. The experimental results are as follows : (1) The most favorable condition for heat treatment of roller chain link-plates for their fatigue strength will be that the link-plates will be first hardened and tempered, and then austempered and tempered, and that the temperature will be 370℃, H_<RA> 72 for both tempering and austempering. (2) For resistance to repeated impact energy from 20 Kg・cm to 50 Kg・cm, the most favorable condition for heat treatment of link-plates will be that the link-plates will be austempered, and that the temperature for austempering will be 370℃ and H_<RA> 72. (3) The link-plates of H_<RA> 78 have proved strongest for repeated impact energy from 80 kg・cm to 640 kg・cm, but have turned out weakest for fatigue strength.
