Abstract

PURPOSE:To prevent contact of a shaft part and a fall-stop ring and to improve durability by regulating the seating position of the fall-stop ring by way of providing a projection for the positioning of the fall-stop ring on the upper edge part of a bearing. CONSTITUTION:A spherical head part 4 of a ball stud 2 surrounded by a bearing 5 is inserted in a housing 8 at first. Next, a cutout 20 of a fall-stop ring 18 is engaged to a projection 7 provided on the bearing 5, the fall-stop ring 18 is placed on a shoulder part 10 of the housing 8 and is fixed at a caulking part 19. Successively, a large open part 15 of a duct cover 13 is fit to a dust cover fitting groove 9 of the housing 8, a cisclip 12 is mounted on the outer periphery of the large open part 15 and a small open part 14 is mounted on the outer periphery of a holder part 3 of the ball stud 2. Consequently, it is possible to get rid of a gap between the inner peripheral surface of an opening 11 of the housing 8 and the outer peripheral surface of the fall-stop ring 18 and accordingly, it is also possible to prevent contact of a shaft part 3 and the fall-stop ring 18.

Therefore, when assembling the ball joint 101 as described above, the inner circumferential shoulder 110 of the housing 108 containing the bearing 105 and the ball head 104 of the ball stud lO2 is assembled.
When the retaining ring 118 is seated, the retaining ring 118 is seated as shown in FIGS.
A bias may occur, and a maximum clearance S may occur on one side (at this time, the clearance r generated on the opposite side of the clearance S is approximately O). When the ball stud 102 swings in this state and swings toward the clearance S side, the handle 108 of the ball stud 102 comes into contact with the retaining ring 118 and wear occurs.
A problem arises in that durability is reduced.
