PROBLEM TO BE SOLVED: To provide a cage which can be prevented from breaking early and is easy in maintenance.SOLUTION: An annular cage 5 is formed by aligning a plurality of cage segments 50 in the circumferential direction, and used in a thrust roller bearing 1. Each of the cage segments 50 includes a circular part 51 and a cage bar part 52 which extends out to the radial-direction inside of the circular part 51, and holds gaps in the circumferential direction between adjacent conical rollers 4. Grooves 51b along the axial direction are formed at end faces 51a circumferentially opposed to each other, of the circular parts 51. Furthermore, in the cage 5, plate springs 55 inserted into the grooves 51b and energizing the circular parts 51 to the circumferential direction are arranged between the end faces 51a, and the cage segments 50 are connected to each other by the plate spring 55. |
