の下端に他端小開口部11を密接させる。First, the handle 8 of the stud 2 and the ball head 9 are formed by forging and cutting. A screw groove 22 is formed in the handle 8 by a rolling process, and a hexagon nut is screwed into the screw groove 22 to form the large flange portion 12. The cup-shaped housing 6 is formed by cutting the inner circumference, the outer circumference, the opening end, and the like, and the cylindrical rod 13 is welded to the outer wall of the cup-shaped housing 6. The sliding member is formed by resin molding to form a cup-shaped sliding member sheet 3. Next, after inserting the ball head 9 of the stud 2 into the opening of the sliding member sheet 3, the sliding member sheet 3 is press-fitted from the opening of the housing 6. Further, an annular press-fitting metal fitting 5 having an L-shaped cross section, which is formed into a substantially cylindrical shape by performing injection molding and vulcanization bonding on the rubber elastic body and having an opening having a smaller diameter than the outer diameter of the sliding member sheet 3 at one large opening 10. Create a buried dust boot 4. The press fitting 5 buried in the large opening 10 of the dust boot 4 is press-fitted and fixed until it hits the opening end 15 of the housing 6, and the small opening 11 at the other end is brought into close contact with the outer periphery of the stud 2 handle 8. large rib portion 12 a hexagonal nut 2 of the shank 8 threaded grooves 22 with the formation of large rib portion 12 is screwed
The small opening 11 on the other end is brought into close contact with the lower end of.

ッド2の柄部8方向へ抜けることがない。Therefore, the annular press fitting 5 having an opening smaller in diameter than the inner diameter of the housing 6 is provided in the dust boot 4.
Since the press fitting 5 is embedded in the large opening 10 and the press fitting 5 is fixed to the opening of the housing 6, it is not necessary to form the annular convex portion by cutting as in the conventional example, and it is not necessary to perform caulking. Further, when a force for pulling out the stud 2 is applied, the inner diameter of the large opening 10 of the dust boot 4 is smaller than the outer diameter of the sliding member sheet 3. Inner circumference of annular press-fitting fitting 5 fitted to
Star stud 2 from sliding member seat 3 housing 6 embracing because it is fixed by the flange 5a lower end 16
It does not come off in the direction of the handle 8 of the pad 2 .

い。In addition, since the lower end 16 of the inner peripheral flange 5a of the annular press fitting 5 is abutted against the opening end 15 of the housing 6, the size in which the sliding member sheet 3 is compressed in the axial direction of the stud can be easily obtained. Incidentally, the sliding torque of the ball joint 1 largely depends on the size of the sliding member sheet 3 compressed in the axial direction of the stud. In the present invention, the inner peripheral flange of the annular press fitting 5 is provided at the opening end of the housing 6.
Since the lower end 16 of the 5a is abutted, its compression dimension is substantially determined by the length of the opening end face and the bottom in the axial direction of the housing 6. However, since it is a part that can be easily obtained with high dimensional accuracy by cutting or the like, it is a conventional example. As described above, in mass production, there is no variation in sliding torque due to a variation in caulking load.

できる。As described above, according to the present invention, an annular press fitting having a cylindrical dust boot large opening with an opening smaller in diameter than the housing inner diameter is buried in the dust boot large opening, Since the press fitting is fixed to the housing opening, it can withstand the load in the pulling direction of the ball joint.
The sliding member sheet moves from the housing to the stud handle.
The housing is open because the press-in fitting prevents it from coming out
Since it is not necessary to caulk the part, it is possible to produce a ball joint with stable sliding torque in mass production , and the number of machining steps is reduced, so that productivity can be improved.
