[Problem] To achieve a structure of a retainer for an angular contact ball bearing, which is capable of reducing stirring resistance or friction generated between the retainer and cured grease. Each of the plurality of column sections has, at one axial end, a first branch section and a second branch section extending in two branches in the circumferential direction; a front end portion of a first branch portion of one column portion and a front end portion of a second branch portion of a column portion adjacent to the one column portion extend in a direction in which the first branch portion and the second branch portion approach each other in the circumferential direction and are connected in the circumferential direction. The front end portion of the second branch portion of the one column portion and the front end portion of the first branch portion of the column portion adjacent to the one column portion extend in the circumferential direction in a direction in which the first branch portion and the second branch portion approach each other, and are connected in the circumferential direction.

    实现能够降低搅拌阻力或者在与固化的润滑脂之间所产生的摩擦的角接触滚珠轴承用保持器的构造。多个柱部分别在轴向一方侧的端部具有:在圆周方向以两股状分支并延伸设置的第一分支部及第二分支部;和在它们之间部分所形成的润滑脂储留槽,一个柱部的第一分支部的前端部和与该一个柱部邻接的柱部的第二分支部的前端部,在圆周方向沿互相接近的方向伸长,且在圆周方向连结,上述一个柱部的第二分支部的前端部和与该一个柱部邻接的柱部的第一分支部的前端部,在圆周方向沿互相接近的方向伸长,且在圆周方向连结。
