A caulked holding member, method for holding a component by caulking, structure of a caulked holding member and caulking apparatus

摘要

During a caulking process, pressure is applied to a pressure receiving shoulder portion (8y) in the same direction as the direction of a clamping force generated by a caulked portion (8b). The clamping force for holding an outer ring (14a) can thereby be increased. Further, a pressure receiving surface (8d) of the pressure receiving shoulder portion (8y) is set higher than an end surface (14b). Thus, no pressure is generated which results from plastic deformation in a direction perpendicular to the direction of the clamping force of the caulking section (8b). In addition, a groove (8z) is formed between the pressure receiving shoulder portion (8y) and an end (8x) that serves as the caulking portion (8b).
