Abstract
A rolling includes an inner race and an outer race, which rotate relative to each other, balls, which are interposed between the inner and outer races, and a retainer, which is arranged between the inner and outer races, for retaining the balls equiangularly. The retainer includes two annular members facing each other in an axial direction and having opposing surfaces each including hemispherical pockets formed in a plurality of circumferential positions, for receiving the balls, the two annular members being coupled together so that the opposing surfaces are brought into abutment on each other. A flange portion extends radially and is provided on a radially inner or outer side of an axial end portion of each of the two annular members.
