PROBLEM TO BE SOLVED: To reduce a torque loss of a rolling bearing by suppressing the intrusion of a lubricant into the bearing.SOLUTION: A rolling bearing comprises an inner ring 2, an outer ring 3, a plurality of conical rollers 4, and an annular cage 5 which holds the plurality of the conical rollers 4. The cage 5 has a small-diameter annular part 11 which is arranged at one side of the conical rollers 4 in an axial direction, and a plurality of column parts 13 which extend to the other side in the axial direction from the small-diameter annular part 11. A recess 41 is formed at a side face 15 of one side of the small-diameter annular part 11 in the axial direction, and a straight face 43 which intersects with a bearing center line C is interposed between an end part 42 of the outside of the recess 41 in a radial direction, and an end part 33 of one side of an external peripheral face 32 of the small-diameter annular part 11 in the axial direction.SELECTED DRAWING: Figure 2 |
