PROBLEM TO BE SOLVED: To provide a multi-stage thrust bearing which enables the reduction of edge load and the like produced on rolling elements, by approximating the amount of deflection of an inner race to that of an outer race. SOLUTION: By adjusting a wall thickness of the inner race and that of the outer race facing the inner race through rollers 5, 6, the amount of deflections of both races can be brought to be closer. Because of this, the edge loads produced on the rollers 5, 6 can be alleviated, row load can be made uniform, and a longer life of the multi-stage thrust bearing can be attained. |
