PROBLEM TO BE SOLVED: To provide a holder for a ball bearing guiding a ball and capable of operating even at high speed.SOLUTION: In a holder 3 for a ball bearing, a ball interposed between inner and outer rings is held in a pocket Pt provided at a plurality of places in a circumferential direction of an annular ring part 5. The annular ring part 5 includes annular parts 6, 6 arranged on both sides in an axial direction, and a column part 7 connecting the annular parts 6, 6 and arranged at a plurality of places in the circumferential direction. The holder for a ball bearing is a ball guide system in which the pocket Pt is formed with the annular parts 6, 6 on both sides in the axial direction, and the column parts 7, 7 adjacent to each other in the circumferential direction. A circumferential contact part with the ball in each column part 7 is a plane 8 extending along the axial direction, and the ball is guided with the plane 8.SELECTED DRAWING: Figure 2 【課題】 ボール案内でありながら高速まで運転可能な玉軸受用保持器を提供する。【解決手段】 この玉軸受用保持器３は、内外輪間に介在するボールを、円環部５の円周方向複数箇所に設けられたポケットＰｔに保持し、円環部５は、軸方向両側に配置される環状部６，６と、これら環状部６，６を繋ぎ円周方向複数箇所に配置される柱部７とを備える。軸方向両側の環状部６，６と、円周方向に隣接する柱部７，７とでポケットＰｔが形成されるボール案内形式である。各柱部７における、ボールとの周方向の接触部を、軸方向に沿って延びる平面８とし、この平面８で前記ボールを案内させる。【選択図】 図２
