PROBLEM TO BE SOLVED: To provide a spline fitting body for suppressing the wobbling of a spline fitting part while facilitating assembling work, and a manufacturing method of the spline fitting body.SOLUTION: A spline fitting body comprises a shaft member 8 in which a shaft spline 9a is formed, and a shaft cylinder member 10 in which a hole spline 11 is formed. Shaft spline teeth 20 have first teeth 21 extending to an axial direction, and second teeth 22 separating from the first teeth 21 in the axial direction. The first teeth 21 and the second teeth 22 are different from each other in phases, the first teeth 21 abut on hole spline teeth 12 of the hole spline 11 located at one side in a peripheral direction, the second teeth 22 abut on the hole spline teeth 12 located at the other side in the peripheral direction, and the shaft member 8 comprises a first shaft part 31 in which a plurality of the first teeth 21 are formed, a second shaft part 32 in which a plurality of the second teeth 22 are formed, and a torsion part 33 which is interposed between the first shaft part 31 and the second shaft part 32, and torsionally deformable.SELECTED DRAWING: Figure 2
