PROBLEM TO BE SOLVED: To provide a cage for a thrust rolling bearing which is suitable for stabilizing a roller guide.;SOLUTION: A cage 14 for a thrust rolling bearing comprises an annular first plate part 16, a second plate part 21, a third plate part 22 and pockets 15 which are formed by punching these plate parts. The first to third plate parts have pocket shearing faces s and pocket fracture faces b as pocket sidewall faces 17w, 21w and 22w for defining the pockets, respectively. At least either of the pocket shearing faces s of the second plate part 21 and the third plate part 22 adjoins the pocket shearing face s of the first plate part 16 in an axial line O direction. In the other case, at least either of the pocket fracture faces b of the second plate part 21 and the third plate part 22 adjoins the pocket fracture face b of the first plate part 16 in the axial line O direction.;SELECTED DRAWING: Figure 4;COPYRIGHT: (C)2019,JPO&INPIT
