Zusammenfassung:	To provide a method for manufacturing a nut for a ball screw capable of suppressing vibration or noise occurring when a ball passes through a boundary part between a nut and a top, and a ball screw.SOLUTION: A nut 20 of a ball screw 1 is manufactured by forming a through hole 23 that penetrates in a radial direction at a position where a ball return passage 42 of the nut 20, press-fitting a circulation top 40 into a predetermined position of the through hole 23 using an insertion jig 50 and a reference jig 60, and pouring an adhesive G into the through hole 23 from which the insertion jig 50 and reference jig 60 have been removed and hardening it.SELECTED DRAWING: Figure 1 【課題】ボールがナットとこまとの間の境界部を通過する際に発生する振動や騒音を抑制することができる、ボールねじ用ナットの製造方法及びボールねじを提供する。【解決手段】ボールねじ１のナット２０は、ナット２０のボール戻し通路４２が設けられる位置に、径方向に貫通する貫通孔２３を形成し、循環こま４０を挿入治具５０と基準治具６０とで貫通穴２３の所定位置に圧入し、挿入治具５０と基準治具６０を取り外した貫通穴２３に接着剤Ｇを流し込んで硬化させて製作される。【選択図】図１
