PROBLEM TO BE SOLVED: To provide a thrust roller bearing capable of reducing a lubricant which stagnates inside of a bearing, reducing a torque and increasing an amount of penetrating oil, while securing rigidity of a retainer.SOLUTION: A thrust roller bearing 1 includes: a retainer 5 having an annular portion 52 composed of an annular plate and provided with a plurality of pockets 51 in the circumferential direction, and a pair of flanges 53, 54 extended in an axial direction respectively from an outer peripheral edge part and an inner peripheral edge part of the annular portion 52; and a plurality of rollers 4 each locked in each of the pockets 51 and rotatably held. Here, lubricant is passed from the inner diameter side toward the outer diameter side. A plurality of cutouts 53a are formed in the circumferential direction in the retainer 5 in a state of radially penetrating the outer flange 53. |
