Zusammenfassung:	To provide a ball bearing with a crown type cage for further suppressing the deformation of the crown type cage due to centrifugal force.SOLUTION: When axial components of distances between a pocket bottom Pb deepest in the axial direction out of pockets 44, 45 opened to one side face of the cage and front ends Pt1, Pt2 farthest in the axial direction from the pocket bottom Pb out of pocket claws 42a, 43b connected to the pocket Pb are the axial lengths of the pocket claws 42a, 43b with respect to the pocket bottom Pb, the cage 4 has the first pocket claw 42a extending to a first axial length A1 and the second pocket claw 43b extending to a second axial length A2 shorter than the first axial length A1.SELECTED DRAWING: Figure 1 【課題】冠形保持器を備える玉軸受において、遠心力による冠形保持器の変形をさらに抑える。【解決手段】保持器の一側面に開口したポケット４４，４５の中で軸方向に最も深いポケット底Ｐｂと、当該ポケットＰｂに接続するポケット爪４２ａ，４３ｂの中で当該ポケット底Ｐｂから軸方向に最も遠い先端Ｐｔ１，Ｐｔ２との間の距離の軸方向成分を当該ポケット底Ｐｂに対する当該ポケット爪４２ａ，４３ｂの軸方向長さとしたとき、保持器４が、第一の軸方向長さＡ１まで延びる第一のポケット爪４２ａと、第一の軸方向長さＡ１よりも短い第二の軸方向長さＡ２まで延びる第二のポケット爪４３ｂとを有する。【選択図】図１
