PURPOSE:To keep the radial shaking quantity constant even when the relative position with a ball group is radially slipped, accompanied by the working error of the raceway surface of the inner ring of a ball bearing to be used, while minimizing the radial shaking quantity relative to the ball to be housed and held as much as possible. CONSTITUTION:In a corrugation holder 5 having two corrugated ring plates 6, 7 axially opposed and connected to each other, the radial clearance S1 between the outer circumferential edge of the swollen part 6a of the first corrugated ring plate 6 and a ball 4 and the radial clearance S3 between the inner circumferential edge of the swollen part 7a of the second corrugated ring plate 7 and the ball 4 are set smaller than the radial clearance S2 between the inner circumferential edge of the swollen part 6a of the first corrugated ring plate 6 and the ball 4 and the radial clearance S4 between the outer circumferential edge of the swollen part 7a of the second corrugated ring plate 7 and the ball 4 as much as possible, respectively. |
