摘要： PROBLEM TO BE SOLVED: To provide a thrust roller bearing for a swash plate type compressor, wherein a roller does not come out of a cage when a PCD length is increased while the inner diameter of the cage remains unchanged. SOLUTION: In the thrust roller bearing 200 to be used for the swash plate type compressor 100, an inner diameter side peripheral wall portion 11 of the cage 9 is forcibly widened into a truncated cone shape with a joint portion 14 to a roller 8 holding portion 15, as a base point. Thus, a clearance between the roller and the inner diameter side peripheral wall portion 11 is reduced, and the roller 8 hardly comes out of pockets 18 in the holding portion 15 even when the PCD length P1 of the roller 8 is increased while the inner diameter D of the cage 9 remains unchanged.
