PROBLEM TO BE SOLVED: To provide a thrust roller bearing for a swash plate compressor, capable of preventing the wear and fracture of a thrust race and rollers due to edge loading resulting from the wrong deflection of the thrust race.SOLUTION: In an abutment portion of a first race 21 or an abutment portion of a second race 22, an annular groove 25 is formed so that a distance La1 from a pitch circle diameter PCD of a thrust roller bearing 20 to a load fulcrum position Sa1 on the first race 21 is approximately equal to a distance Lb from the pitch circle diameter PCD of the thrust roller bearing 20 to a load fulcrum position Sb on the second race 22.SELECTED DRAWING: Figure 2 |
