PROBLEM TO BE SOLVED: To reduce the load when a fastening member is turned to be fastened to a screw part of a drive shaft.SOLUTION: The assembly apparatus includes: a press-fitting device 1 for grasping and pulling a tip of a drive shaft S inserted into an inner spline hole Ha of an axle hub H, and relatively press-fitting an outer spline Sa of the drive shaft S within the inner spline hole Ha; and a fastening device 5 for fastening a fastening member T to a screw part Sb at the tip of the drive shaft S, press-fitted within the inner spline hole Ha of the axle hub H. The press-fitting device 1 includes: a pilot screw 11 having a chuck 10 to be screwed with the screw part Sb of the drive shaft S, for thereby holding the tip; a push screw 12 disposed coaxially and rotating relatively, with respect to the pilot screw 11, for thereby displacing the pilot screw 11 in an axial direction; and rotation blocking means 13 for blocking the rotation of the axle hub H around the axis.

    【課題】締結部材を回転させてドライブシャフトのねじ部に締結する際の負荷を低減させる。【解決手段】組付け装置は、アクスルハブHの内スプライン孔Haに挿通されたドライブシャフトSの先端を把持して引っ張り、ドライブシャフトSの外スプラインSaを内スプライン孔Haに相対的に圧入させる圧入装置1と、アクスルハブHの内スプライン孔Haに圧入されたドライブシャフトSの先端のねじ部Sbに締結部材Tを締結させる締結装置5とを備えている。圧入装置1は、ドライブシャフトSのねじ部Sbに螺合することにより先端を把持するチャック10を備えたパイロットスクリュ11と、パイロットスクリュ11と同軸上に配置されて相対回転することによりパイロットスクリュ11を軸方向に変位させるプッシュスクリュ12と、アクスルハブHの軸周りの回転を阻止する回転阻止手段13とを備えている。【選択図】図2
