[Problem] To achieve a structure of an angular ball bearing cage capable of reducing stirring resistance or friction generated between the cage and solidified grease.[Solution] Each of a plurality of column portions includes a first branch portion and a second branch portion that are provided, in an end portion on one side in the axial direction, to extend in the circumferential direction in a form of a bifurcation; and a grease storage groove formed in a portion therebetween. The tip-end portion of the first branch portion of one column portion and the tip-end portion of the second branch portion of a column portion adjacent to the one column portion extend in directions approaching each other in the circumferential direction and are connected to each other in the circumferential direction. The tip-end portion of the second branch portion of the one column portion and the tip-end portion of the first branch portion of a column portion adjacent to the one column portion extend in directions approaching each other in the circumferential direction and are connected to each other in the circumferential direction.
