In addition to the pressure for swaging applied when swaging is performed, a pressure in the direction the same as the direction of the holding force exerted by a swaged portion is applied to a pressure receiving edge portion of a bearing holder by the pressure applied by a swaging roller. As a result, the elastic deformation in a circumferential wall portion that is not bent is advanced and the amount of elastic deformation of the bearing holder in the axial direction is reduced, so that it is possible to increase the difference in the amount of elastic deformation between the bearing holder and an outer race. Thus, the axial residual stress in the bearing holder is increased after the swaging is completed, as compared to the case of the ordinary swaging. Accordingly, it is possible to increase the holding force for holding the outer race.
A swaging hold method of swaging for holding a held member, comprising forming a swaged portion by bending an end portion of a workpiece by swaging to hold the held member along a base portion of the workpiece by a holding force exerted by the swaged portion,
A swaging hold method of swaging for holding a held member, comprising:
A swaging roller for forming a swaged portion by bending an end portion of a cylindrical workpiece by swaging to hold a held member along a base portion of the workpiece by a holding force exerted by the swaged portion, the swaging roller comprising:
A swaging hold workpiece, of which an end portion is bent by swaging to form a swaged portion to hold a held member along a base portion of the workpiece by a holding force exerted by the swaged portion,
