Description

【０００２】
【従来の技術】
所謂デフレクタを用いてボールの無限循環路を形成したボールねじ装置としては、例えば、特開平６−２８８４５８号公報に開示されたものが知られている。このボールねじ装置は、螺旋状のボール転動溝が形成されたねじ軸と、上記ボール転動溝に対向する螺旋状の負荷転動溝を有すると共にボールを介して上記ねじ軸に螺合するナット部材と、このナット部材の内周面に嵌合してボールの無限循環路を形成するデフレクタとを備えている。 0002.
[Conventional technology]
As a ball screw device in which an infinite circulation path of a ball is formed by using a so-called deflector, for example, a ball screw device disclosed in Japanese Patent Application Laid-Open No. 6-288458 is known. This ball screw device has a screw shaft in which a spiral ball rolling groove is formed and a spiral load rolling groove facing the ball rolling groove, and is screwed to the screw shaft via a ball. It includes a nut member and a deflector that fits on the inner peripheral surface of the nut member to form an infinite circulation path for the ball.
