To realize a structure capable of efficiently reflowing lubricant adhering to a rolling surface of a ball between an outer ring raceway and an inner ring raceway even in a case where an inner diameter of a pocket approaches an outer diameter of the ball.SOLUTION: The inner surface of a pocket 12 of an inclined holder 5 comprises a one-side surface in the axial direction of a small diameter rim part 10, and has an inside guide surface 16 that is a concave curved surface constituting the other side part in the axial direction of a radially inside part, and an outside guide surface 19 that is a concave curved surface constituting a one-side part in the axial direction of a radially outside part. Also, the inner surface of the pocket 12 is an inside retraction surface 17 and an outside retraction surface 20 in which a portion deviated from the inside guide surface 16 and the outside guide surface 19 exists at a position retracted from the rolling surface of a ball with respect to the inside guide surface 16 and the outside guide surface 19, and the inside guide surface 16 and the outside guide surface 19 are separated by the inside retraction surface 17 and the outside retraction surface 20.SELECTED DRAWING: Figure 5

    【課題】ポケットの内径を玉の外径に近づけた場合でも、玉の転動面に付着した潤滑剤を外輪軌道と内輪軌道との間で効率良く還流させることができる構造を実現する。【解決手段】傾斜型保持器5のポケット12の内面は、小径リム部10の軸方向片側面を含み、径方向内側部の軸方向他側部を構成する凹曲面である内側案内面16と、径方向外側部の軸方向片側部を構成する凹曲面である外側案内面19とを有する。また、ポケット12の内面は、内側案内面16及び外側案内面19から外れた部分が、内側案内面16及び外側案内面19よりも玉の転動面から退避した位置に存在する内側退避面17及び外側退避面20であり、内側案内面16と外側案内面19は、内側退避面17及び外側退避面20により離隔されている。【選択図】図5
