With the model built-up crankshaft of mild steel, the diameter of its crank pin in 56mm, being used as a test piece, the fatigue tests under repeated bending were carried out to examine the fatigue strength of the crank pin, which was shrink-fitted. By changing the ratio of shrink-fit from 10×10^<-4> to 30×10^<-4>, the notch factor against the shrink-fitted section was sought. As a result, it was found that within the range where the ratio of shrink-fit was smaller than 20×10^<-4>, the notch factor increased proportionately with the growth of the ratio of the shrink-fit. On the other hand, however, when the range of the ratio of the shrink-fit was larger than 20×10^<-4>, the notch factor world remain constant.
