Zusammenfassung:	To provide a ball bearing for a wave reduction gear capable of suppressing generation of excessive stress on a retainer.SOLUTION: In a retainer 324, 0.05≤K10/D2≤0.15 ... (1) is satisfied, when a minimum dimension of a clearance in an I direction represented by a difference between a distance between pole portions 324B adjacent to each other in the I direction and a diameter of a ball 323 in a pocket 324p in a state that a center of the pocket 324p and a center of the ball 323 in the pocket 324p are agreed with each other, is K10 and a diameter of the ball 323 is D2.SELECTED DRAWING: Figure 5 【課題】保持器への過大な応力の発生を抑制し得る波動歯車減速機用の玉軸受を提供する。【解決手段】保持器３２４は、ポケット３２４ｐの中心とポケット３２４ｐ内の玉３２３の中心とが一致した状態で、ｌ方向に隣り合う柱部３２４Ｂ間の距離と、上記ポケット３２４ｐ内の玉３２３の直径との差で表されるｌ方向の隙間の最小寸法をＫ１０、玉３２３の直径をＤ２としたとき、０．０５≦Ｋ１０／Ｄ２≦０．１５...（１）が成立する。【選択図】図５
