<P>PROBLEM TO BE SOLVED: To provide a roller bearing which is easily assembled while suppressing degradation in the strength of a bar. <P>SOLUTION: The roller bearing 1 includes an inner ring 5, an outer ring 3, a cage 6A, and a plurality of rollers 7. The cage 6A includes: a pair of annular rims which are arranged concentrically with each other and at an interval in an axial direction; and a plurality of bars bridged between both rims. A part surrounded in four directions with the inner side surfaces of both rims and the circumferential direction-side faces of bars adjacent to each other in the circumferential direction is set as a pocket. An axial slit is formed in a part excluding the axial center of the peripheral surface of at least one bar of the plurality of bars. <P>COPYRIGHT: (C)2012,JPO&INPIT |
