TANDEM ANGULAR TYPE BALL BEARING

PROBLEM TO BE SOLVED: To provider a structure by which a load carrying capacity can be increased without increasing a size in an axial direction or a size in the axial direction can be shortened without lowering the load carrying capacity.SOLUTION: A tandem angular type ball bearing includes a pair of holders 13d, 13e independent from each other and having diameters different from each other in respective rows. Both holders 13d, 13e are crown type holders in which a plurality of elastic pieces 15b, 15c are protruded in one faces in the axial direction of rims 14d, 14e, and parts whose three directions are surrounded by one faces of the rims 14d, 14e in the axial direction and the side faces in a peripheral direction of the pair of elastic pieces 15b, 15c adjacent in a peripheral direction are pockets 16b, 16 rollably holding respective balls 7A, 7B. The rims 14d, 14e constituting the crown type holder are located at both openings of an inner space 17. Distal ends of the respective elastic pieces 15b, 15c are not protruded to the opposite sides of the rims 14d, 14e beyond the respective balls 7A, 7B.
