Summary:Provided is a ball bearing that can prevent the vibration of a retainer while preventing the deformation of the retainer in a harmonic drive gear device. This ball bearing (1) comprises: a deformable inner ring (2); a deformable outer ring (3) that is installed outside the inner ring (2); a plurality of spherical rolling elements (4) that are provided between the inner ring (2) and the outer ring (3); and a retainer (5) in which a plurality of pockets (10) are circumferentially provided at intervals therebetween, the plurality of rolling elements (4) being respectively accommodated in the pockets (10). Each of the plurality of pockets (10) has a pocket surface (11) that spreads around a pocket axis (x1) that extends in a radial direction, and a flange section (20) that protrudes toward the pocket axis (x1) from the pocket surface (11). The pocket surfaces (11) are formed so as to accommodate the rolling elements (4) with an interval therebetween, and the flange section (20) is formed so as to be in contact wi
