[Problem] To more smooth a surface of a resin coating layer which is provided on a sliding portion of a torque transmission shaft, when the torque transmission shaft is manufactured. [Means for Solution] In a method of manufacturing an intermediate shaft 5 comprising: an internal shaft 35 having an external spline 37; a tubular external shaft 36 having on an inner circumference thereof an internal spline 38; and a resin coating 139 provided on the external spline 37, a central axis line of an internal shaft manufacturing intermediate product 147 and a central axis line of an external shaft manufacturing intermediate product 46 are aligned with each other, and the internal shaft manufacturing intermediate product 147 and the external shaft manufacturing intermediate product 46 are held in such a way that the central axis lines thereof can be adjusted, in a heating adaptation step (Fig. 4(h)). In this state, the internal shaft manufacturing intermediate product 147 and the external shaft manufacturing intermediate product 46 slide relatively in an axial direction X1. Thus, a surface of the resin coating 139 is made smooth. In the heating adaptation step, a grease 48 is interposed between the internal shaft manufacturing intermediate product 147 and the external shaft manufacturing intermediate product 46.
