Abstract
A method of manufacturing a spline telescopic shaft, includes a sliding step of sliding in an axial direction an inner shaft manufacturing intermediate member and an outer shaft manufacturing intermediate member, in one of which a resin coating is disposed on splines. In the sliding step, a sliding load of the inner shaft manufacturing intermediate member and the outer shaft manufacturing intermediate member is detected, and sliding is ended at a timing when the detected sliding load reaches a threshold load which is determined based on an initial sliding load detected at a start of the sliding.
