摘要：An interlocking groove (37c) extending in a circumferential direction is formed inan outer ring (31), in a stepped part outer peripheral surface (37a) of a small-diameterstepped part (37). A securing plate (40) is provided with a plurality of interlocking pawls

(49) that protrude diametrically inward from the inner periphery of the securing plate(40) sectioning off a fitting hole (41), and that interlock with the interlocking groove (37c).With the fitting hole (41) fitted over the small-diameter stepped part (37), the

interlocking pawls (49) are formed by axially pressing a back surface (46) of the securingplate (40) and a tapered part (47) formed in advance in the peripheral edge between theback surface (46) and the inner peripheral surface of the fitting hole (41), and elasticallydeforming the inner periphery of the securing plate (40) so that the inner peripherybulges diametrically inward, and the interlocking pawls (49) interlock with theinterlocking groove (37c). It is thereby possible to stably mold the interlocking pawlsthat interlock with the interlocking groove of the small-diameter stepped part whilepreventing interference with the outer ring, and productivity can be improved.
