Claims (2)

An inner ring having an inner ring raceway on the outer peripheral surface, an outer ring having an outer ring raceway on the inner peripheral surface, a plurality of balls disposed on a circumference between the inner ring raceway of the inner ring and the outer ring raceway of the outer ring, A rectangular hole pocket formed by combining split members formed by dividing in the axial direction between the inner ring and the outer ring and holding the balls in the circumferential direction. It is a rolling bearing that is configured to hold both balls in the part,
The structure in which the cage is positioned in the radial direction between the inner ring and the outer ring is configured such that the cage is in the radial direction with respect to the ball only by the axial inner wall surface of the pocket portion of the rectangular hole of the cage. As a ball guide-shaped configuration that cannot be relatively moved, a gap is formed between the outer circumferential surface of the cage and the inner circumferential surface of the outer ring, and the ball guide shape of the pocket portion of the cage is a rectangular hole pocket. Is a convex shape formed toward the ball at at least one position in the radial inner diameter side and outer diameter side positions of only the inner wall surface in the axial direction of the portion, and the convex shape abuts against the ball in the radial direction Accordingly , the rolling bearing is configured such that the cage cannot be moved relative to the ball in the radial direction . The rolling bearing according to claim 1,
A rolling bearing, characterized in that an axial end portion of the inner peripheral surface of the outer ring is formed in a tapered shape so as to expand from the outer ring raceway toward the end surface direction .
