[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.
