For example, the technology of the above-mentioned Japanese Patent Application Laid-open Nos. 56-10816 and 59-126112 has an arm a, as shown in FIGS. 5a and 5b.
The cylindrical part b of the housing c is fixed by caulking into the groove d of the housing c, but in the case of a, a tight connection cannot be obtained unless the height of the cylindrical part b and the groove c are made accurately. Figure b shows a tool for forming an outwardly expanding portion e at the tip of the cylindrical portion b, a tool for fitting this outwardly expanding portion e into a groove c, and a tool for pressing the apex of the outwardly expanding portion e. There was a problem in that the equipment and process became complicated.

る。(Means for Solving the Problems) The present invention employs caulking as a means for fixing the arm and housing, instead of using welding that is prone to rust or clips that are prone to looseness, but the caulking means has been improved. The arm and the housing are securely fixed together by an extremely simple means, and its structure is such that a ball joint is caulked to the cylindrical portion of the arm end, and a ball joint is attached to the outer surface of the housing 6.
A cylindrical surface 11 press-fitted into a cylindrical portion 15 formed on the arm 7, a flange 10 supporting one end of the cylindrical portion 15, and shoulders 12 and 19 of the cylindrical surface 11 formed into an annular groove shape with a deep inner circumferential side of the cylindrical portion 15. It is characterized by having caulked portions 12a and 19a caulked at the other end.

2. A reduced diameter part 13 and a bottom plate caulking part 14 are provided, and on the other hand, a cylindrical part 15 is formed to protrude by burring on the arm 7, and its tip is cut off and the length l is formed on the cylindrical surface of the housing 6. 11 length L
Make it slightly lower than The shoulder portion 12 is sloped inwardly and downwardly and has a thin outer peripheral portion to facilitate caulking. In the figure, reference numeral 16 indicates a reinforcing rib formed by bending the side of the arm 7.

める。 To fix both members 6 and 7, press fit the cylindrical surface 11 of the housing 6 into the cylindrical portion 15 of the arm 7 so that the flange 10 is in contact with the lower surface of the arm 7, and place it on the pedestal 17. Then, the punch 18 is lowered to press the shoulder portion 12 downward. This results in
The shoulder portion 12 is caulked as shown at 12a in FIG. 3, and the arm 7 is fixed by sandwiching the cylindrical portion 15 between the caulking portion 12a and the flange 10. As shown in FIG.
The tip of No. 8 also has a launch angle that is smaller in angle than the slope, but slopes in the same direction. Therefore, the amount of deformation of the corner portion 12 is large, and sufficient plastic deformation is performed.
A strong caulked portion 12a that does not loosen can be obtained. At this time, the diameter of the cylindrical surface 11 expands slightly as the pressure is applied in the axial direction, further strengthening the pressing force with the cylindrical portion 15.

ることができる。(Effect of the invention) The present invention holds the inner peripheral surface of the cylindrical portion 15 of the arm 7 with the cylindrical surface 11 of the housing 11, and the flange 1
Since both ends of the cylindrical portion 15 can be held by the crimped portion 12a or 19a and a strong tightening force can be applied to these portions, the cylindrical portion 15 can be held in both the radial and axial directions. It can be fixed securely. And the cylindrical part 15 is the housing 6
Since the cylindrical portion 15 has the axial length l, the stress against the load in the radial direction or bending direction applied to the cylindrical surface is reduced, and the durability is improved. Furthermore, even if the lengths l and L in the axial direction and the value of the dimensional difference L-l are slightly different, there is no play in the caulked portion 12a or 19a.
Since it does not cause any cracking or large variations in caulking force, it can be firmly fixed without loosening. Furthermore, since the caulked portions 12a, 19a are plastically deformed at an ejecting angle in which the inner peripheral side becomes deeper, a large plastic deformation can be performed even though the caulking width is small, and a strong caulked connection can be obtained. Furthermore, unlike fixing by welding, no heating is required, so it is possible to prevent a decrease in product value due to rusting.
