PROBLEM TO BE SOLVED: To easily assemble a rolling element in safety even when a bearing ring is integrally mounted, while preventing the come-off of the rolling element in a rolling bearing wherein the spin slip of the rolling element and the bearing ring is inhibited, and the torque is lowered by lowering the rolling resistance. SOLUTION: This rolling bearing has a small groove 4 on an inner ring raceway groove for assembling the rolling element 5 in a raceway groove space while rotating the same, after outer and inner rings 1, 2 and a ball-cage 6 are assembled. This rolling bearing satisfies A/D is 98.0-99.5% in a state in which the relative raceway grooves 3 in the pair of raceway rings 1, 2 are aligned, when a distance connecting a rolling element insertion-side edge part 3a of the raceway groove 3 in the outer ring 1 and a rolling element anti-insertion side edge part 4a of a rotating groove 4 for assembling the rolling element in the inner ring 2, is A, and a maximum diameter of the rolling element is D. The ball-cage 6 is mounted only on an axial pocket face 7b of a pocket 7, and the other face side is opened. COPYRIGHT: (C)2005,JPO&NCIPI
