PROBLEM TO BE SOLVED: To provide a cage for a thrust roller bearing constituted by fitting two cage members in the direction of a central axis and preventing the fitted holder members from rotating relatively in the direction around the central axis centered on the central axis of the cage when assembling the cage or using the bearing. SOLUTION: In the cage member 1a on one side, a small window 5 is formed continuously with a pocket from the pocket 4 to an inner flange 9 close to the central axis CL, and the width of the small window is smaller than that of the pocket. In the other cage member 1b, a projection 2 engaging with the small window of the cage member 1a is formed, and these two holder members 1a, 1b are fitted to constitute the cage 1.
