摘要

A cage, which is annular, and is used in a thrust roller bearing, includes a plurality of cage segments arranged in a circumferential direction. Each of the cage segments includes an arc portion; and a bar portion that extends radially inward from the arc portion and that maintains a circumferential interval between rollers adjacent to each other. A groove portion extending along an axial direction is formed at each of end faces of the arc portions, the end faces facing each other in the circumferential direction. In the cage, elastic bodies are inserted into the groove portions and urge the arc portions in the circumferential direction, each of the elastic bodies is disposed between the end faces facing each other, and the cage segments are connected to each other by the elastic bodies.
