PROBLEM TO BE SOLVED: To provide a thrust roller bearing preventing a central axis of a race movable in the radial direction without guiding by a counterpart member from shifting from the center of rotation of a shaft. SOLUTION: This thrust roller bearing 10 is disposed between a counterpart member 30 and a counterpart member 32 on the outside diameter side of the shaft 34. The thrust roller bearing includes: a plurality of rollers 12; a cage 14; a race 16; and a race 20. A cylindrical receptor part 24 extending to the counterpart member 32 side is formed at the inside diameter side end of the race 20 on the inside in the radial direction from the inside diameter side end of the counterpart member 32. The race 20 is set movable in the radial direction without guiding by the counterpart member 32. A lubricant passage 36 for supplying lubricant is formed at the axis part of the shaft 34. Oil holes 38 reaching the lubricant passage 36 are formed on the two circumferential portions at positions facing the receptor part 24 of the race 20 in the outside diameter part of the shaft 34.
