<p><P>PROBLEM TO BE SOLVED: To provide a rolling bearing in which a cage is stably disposed. <P>SOLUTION: The rolling bearing comprises a plurality of rollers and the cage segment 15a retaining the rollers and divided by a line extending along the axial direction. The cage segment 15a includes a plurality of beam portions 22a, 22b, 22c, 22d extending along the axial direction to form first pockets 23a, 23c, a second pocket 23b for retaining the rollers, and a connecting portion connecting the above and extending in the circumferential direction. Outer diameter side roller stopping portions 24a, 24b, 24c, 24d for restricting movement of the rollers retained in the first pockets 23a, 23c to the outer diameter side are provided on the outer diameter side of the beam portions 22a-22d on both sides in the circumferential direction of the first pockets 23a, 23c. An inner diameter side stopping portion for restricting movement of the rollers retained in the second pocket 23b to the inner diameter side is provided on the inner diameter side of the beam portions 22b, 22c on both sides in the circumferential direction of the second pocket 23b. The cage segment 15a becomes a roller guide. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
