Abstract
In machining a pocket () installing therein a rolling element, tools () are prepared whose milling parts () have contours which coincide with the sectional configuration of the pocket resulting when the pocket has been machined along a retainer radial direction (Z), and the milling parts () of the tools () are inserted into a prepared hole for the pocket which is provided in advance and are then translated in a retainer revolving direction (Y) and axial direction (X), respectively, for forming the pocket. Accordingly, it is possible to provide a retainer for rolling bearings that has high accuracy in machining pockets and which is suitable for an integral one-piece retainer.
