PROBLEM TO BE SOLVED: To provide a ball screw device including a retainer of low costs, disposed between the ball screw device and a ball nut and having a flange portion, a steering device using the ball screw device, and a manufacturing method of the retainer of the ball screw device.SOLUTION: A ball screw device 40 includes a ball screw shaft 20, a ball nut 21, rolling balls 24, and a retainer 27. Both side faces 26a, 26b of a retainer groove 26 are formed to permit radial outward movement of the rolling balls 24 and to restrict radial inward movement of the same, and weld joints 27c1, 27c2 are disposed on both ends of the retainer groove 26 in an axial direction of the retainer 27.SELECTED DRAWING: Figure 5B

    【課題】ボールねじ軸とボールナットとの間に配置される鍔部を有した低コストなリテーナを備えるボールねじ装置、ボールねじ装置を用いたステアリング装置、及びボールねじ装置のリテーナの製造方法を提供する。【解決手段】ボールねじ装置40は、ボールねじ軸20と、ボールナット21と、転動ボール24と、リテーナ27と、を備える。そして、リテーナ溝26の両側面26a、26bは、転動ボール24の径方向外方への移動を許容し且つ径方向内方への移動を規制するように形成され、リテーナ27の軸方向におけるリテーナ溝26の両端に溶接継手27c1、27c2を備える。【選択図】図5B
