<P>PROBLEM TO BE SOLVED: To provide a rolling bearing that can suppress uneven distribution of rolling elements in the circumferential direction, and can suppress non-repeatable runout of a rotary shaft. <P>SOLUTION: This rolling bearing 10 includes: an inner race 11 having an inner ring raceway surface 11a at an outer circumferential surface; an outer race 12 having an outer ring raceway surface 12a at an inner circumferential surface; a plurality of rolling elements 13 rollably arranged between the inner ring raceway surface 11a and the outer ring raceway surface 12a; and a synthetic resin cage 15 in which a cut part 14 is formed at one part or more in the circumferential direction and which holds the plurality of rolling elements 13 substantially equidistantly in the circumferential direction. A relation of S<SB POS="POST">3</SB>=S<SB POS="POST">1</SB>+S<SB POS="POST">2</SB>+ΔC is satisfied, where ΔC is the width dimension of the cut part, S<SB POS="POST">1</SB>is the width dimension of one columnar part in the cut part, S<SB POS="POST">2</SB>is the width dimension of another columnar part, and S<SB POS="POST">3</SB>is the width dimension of the columnar part not being cut of the cage. <P>COPYRIGHT: (C)2012,JPO&INPIT |
