PROBLEM TO BE SOLVED: To provide a thrust roller bearing which secures long life by improving its lubricity and contact pressure of a roller. SOLUTION: Since cutouts 101d, 102d in an arc shape are smoothly connected with edges of guide parts 101b, 102b, waviness on race surfaces of the main bodies 101a, 102a hardly occurs when folding the guide parts 101b, 102b, and thus a long life of the thrust roller bearing 100 is secured by generating even contact pressure on the rolling roller 103.
