摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a drive shaft which can improve dimensional accuracy without relying upon cutting and increasing strength by suppressing the nonuniformness of quenching.SOLUTION: The maximum and minimum diameters of a solid bar body 10 (shaft-like body) conveyed in the longitudinal direction are obtained by measuring the diameter at a same portion from multiple directions, and the difference between the maximum and minimum diameters (diameter difference) is obtained. A product the deviated diameter difference of which is within a preset threshold is selected as an acceptable one, and a product the deviated diameter difference of which exceeds the threshold is selected as a rejected one. The rejected one is excluded, and the acceptable one is cut off, machined, and induction hardened. Consequently, a drive shaft is obtained from the acceptable product.
