Abstract

　ねじみぞ内のボールがスプラインみぞへ肩乗り上げするおそれがないボールスプライン付きボールねじを提供する。 　ボールスプライン付きボールねじは、ねじみぞ6および軸方向にのびる複数の直線状スプラインみぞ7が外周面に形成されたねじ軸1と、ねじ軸1が通されてねじ軸1のねじみぞ6に対応するねじ用ボール循環路が形成されたねじ用ナット2と、ねじ軸1が通されてねじ軸1のスプラインみぞ7に対応するスプライン用ボール循環路が形成されたスプライン用ナット3と、ねじ用ナット2のねじ用ボール循環路に配設された複数のねじ用ボール4と、スプライン用ナット3のスプライン用ボール循環路に配設された複数のスプライン用ボール5とを備えている。ねじ軸1におけるスプラインみぞ7の底7aの径方向の位置が、ねじみぞ6の最大負荷時のボール接触部分の最も径方向外側の部分よりも径方向外側にある。
