    摘要: A cage element 18 in which pillar element portions 17, 17 are made to project from a rim portion 11 is manufactured by performing a punching process and a bending process on a metal plate. With rim portions 11, 11 of a pair of cage elements 18, 18 disposed concentrically with each other and phases in a circumferential direction of the respective pillar element portions 17, 17 made to coincide with each other, distal ends of the respective pillar element portions 17, 17 are butted to each other to be welded together, whereby respective pillar portions are made. The roundness of the respective rim portions 11, 11 and the shape accuracy and interval accuracy of these respective pillar portions are improved without performing troublesome processes, so as to solve the problem.
