Zusammenfassung:	To provide a manufacturing method of a ball screw device capable of improving a degree of freedom in assembly and reducing labor therefor.SOLUTION: A manufacturing method of a ball screw device includes a nut unit preparation step, a screw shaft preparation step, and an assembly step. In the nut unit preparation step, a nut unit is prepared by assembling a circulation component, a ball and a temporary shaft for falling prevention of the ball to a nut in which an inner peripheral track surface is provided. In the screw shaft preparation step, a screw shaft in which an outer peripheral track surface is provided is prepared. In the assembly step, the ball screw device is manufactured by exchanging the temporary shaft of any nut unit with any screw shaft after the nut unit preparation step and the screw shaft preparation step.SELECTED DRAWING: Figure 3 【課題】組み立ての自由度とその労力を軽減できるボールねじ装置の製造方法を提供する。【解決手段】ボールねじ装置の製造方法は、ナットユニット準備工程と、ねじ軸準備工程と、組み立て工程と、を含む。ナットユニット準備工程は、内周軌道面が設けられたナットに循環部品、ボール、及びボールの脱落防止のための仮軸を組み付けられたナットユニットを準備する。ねじ軸準備工程は、外周軌道面が設けられたねじ軸を準備する。組み立て工程は、ナットユニット準備工程とねじ軸準備工程の後に、任意のナットユニットの仮軸を任意のねじ軸に交換し、ボールねじ装置を製造する。【選択図】図３
