To caulk a ring in a housing to enable processing of fixing a ball seat in a short tact time, thereby reducing a manufacturing cost.SOLUTION: A ball joint J1 comprises a circumferential groove 21c1 provided on an outer periphery of a trunk part of a housing 21, and further comprises a ring 24 arranged inside an opening end part of the housing 21 and set on a ball seat 12. Then, a roller 31 is inserted into the groove 21c1 of the housing 21, a groove forming trunk part 21d is projected into the housing 21 in a circumferential manner while pressing the groove forming trunk part 21d at a portion where the groove 21c1 is formed in the insertion direction with the inserted roller 31, and this projection forms a convex part 21e that caulks the ring 24.SELECTED DRAWING: Figure 2

    【課題】ハウジング内のリングをカシメてボールシートを固定する加工を短いタクトタイムで可能とし、製造コストを下げること。【解決手段】ボールジョイントJ1において、ハウジング21の胴部の外周に、周回状に形成された溝21c1を備え、更に、ハウジング21の開口端部の内側に配置され、且つボールシート12の上にセットされたリング24を備える。そして、ハウジング21の溝21c1にローラ31を挿入し、この挿入されたローラ31で、溝21c1が形成された部位の溝形成胴部21dを挿入方向に押圧しながら溝形成胴部21dをハウジング21内に周回状に突出させ、この突出によりリング24をカシメる凸部21eを形成する。【選択図】図2
