In succesion to previous reports, repeated impact fatigue tests and repeated revolving tensile fatigue tests were carried out for the bicycle roller chains and the smalll size roller chains for power transmission. As the results of two kinds of fatigue tests, it is made clear that results obtained by revolving tensile fatigue tests completely coincide with those by impact fatigue tests, and that the critical part of the chains is the cross section of the eye-end part of the roller-links perpendicular to longitudinal direction, where bushes are press-fitted and concentrated stresses are produced. Fatigue limits of the bicycle and power transmission roller chains are 10kg/mm^2 and 14kg/mm^2 respectively, and taking the fact into consideration that the various link plates for the power transmission roller chains are similar figures, we shall be able to conclude that the fatigue limits of roller chains of any size for power transmission are approximately 14kg/mm^2 which was mentioned above, except certain chains made of the special materials.
