題を招来する。Conventionally, this divine holder has been manufactured by the process shown in the block diagram of Fig. 1, and the concrete (/( is shown in Fig. 2)
1) or 4) As shown in K, on the band-shaped metal plate AO, -
Open holes 11a (see Fig. 2 (1)) at predetermined intervals (Fig. 2 (1)), then cut into pieces BO of a predetermined length (Fig. 2 (2)), and curl the pieces BO. Assuming the desired cylindrical shape (Fig. 2 (3)), 1f inside the nucleus.
i) A cage (FIG. 2 (4)) is manufactured by joining the Co end faces 2a by means such as electric resistance welding or brazing. However, according to this manufacturing method (as described above, since the belt-shaped metal plate AO has the opening tta at one end, the outer diameter part 3 of the cage becomes tapered 31 after welding as shown in FIG. occurs, which impedes circular rotation of the bearing, and in extreme cases, the pocket opening expands, causing the cage to come off while the bearing is rotating, and even damage the outer periphery of the cage and the inner diameter of the outer ring ( (not shown) come into contact with each other.

Next, the present invention will be explained with reference to examples. FIGS. 4 and 4 are block diagrams showing the steps, and FIG. 5 (11 to 5) is a specific explanatory diagram. That is, holes (1) for two cages are formed on the band-shaped metal plate A1 at predetermined intervals (see FIG. 5(I)
), then the fragment 131K of a predetermined length is cut to a regular length (FIG. 5 (2)), and the fragment B1 is cut into a desired cylindrical cylinder C1 (FIG. 5 (3)), inside the nucleus @ (-1 The end faces 2 of the cage intermediate body D1 are joined by means such as electric resistance welding or brazing to form the cage intermediate body D1.Then, the cage intermediate body is cut and separated at the center stone in the width direction, thereby forming two pieces. It is possible to obtain a retainer El for 10 minutes.

That is, a gold silk plate is drawn and processed to form a cylinder C2 (Fig. 7 (1)), and then finished to a predetermined width dimension to form a cylinder C2 (Fig. 7 (2)). A pocket for two cages is formed on the cylindrical surface of the cylinder. space 12 for communicating the respective pockets is provided at a predetermined interval to hold the retainer intermediate body (Fig. 7 (3)); By cutting and separating at , two cages E2 can be obtained.

のである。As explained by hIQ'tlJ, according to the present invention, there is a method for manufacturing two cages at the same time, by welding the ends of pieces cut to a predetermined length or by drawing After manufacturing a cage intermediate body finished to a certain width and with good dimensions and shape, the middle position kK cut 141 of the MfJ cage intermediate body is separated, so there is no deformation in the cage after separation. In addition, since two cages can be obtained at a time, the number of steps can be reduced and the cost can be reduced.
