<p>PROBLEM TO BE SOLVED: To prevent creep for a long time, which is easy to generate in a rolling bearing in which a shaft part of a rotation member is fitted, with clearance, into a bearing ring of either one of an inner ring and an outer ring, maintaining stable rotation.SOLUTION: A roller bearing 10 is mounted on a rotation shaft of a roller, and includes a cage 14 having a plurality of pockets 12 formed along a circumferential direction of a cylindrical cage body 11, and rollers 15 rotatably held in the pockets 12, respectively. A fixation device includes a rotation shaft and a pair of roller bearings mounted on the rotation shaft in both sides. A pair of flange parts 13 is provided to extend inward in a radial direction from opposite ends of the cage 14 in an axial direction.</p> |
