はめ込んだものである。As shown in the partial cross section passing through the ball shaft in FIG. 1, the lower arm of the wheel support device for a dynamic rolling vehicle is inserted into the hole 2a of the cylindrical burring part 2 at the end of the lower arm 1 made of sheet metal.
A housing 4 that holds the ball 3a of the ball joint 5 is fitted therein.

ある。The housing 4 has a stepped part 4a that matches the inner diameter d of the burring part cylindrical hole 2a, and a groove 4b in which the edge 2b of the first cylindrical hole 2a is narrowed, with a diameter D+ slightly smaller than the outer diameter D1 of the cylindrical hole 2a. ) A stepped portion 4C having a relationship of D is provided. Therefore, in order to attach the housing 4 to the cylindrical hole edge 2b of the burring part, first insert the screw 4 so that the stepped part 4a is attached to the cylindrical hole edge 2b.
a and press until the stepped part 4C abuts against the cylindrical hole edge 2b.
Two presses are required. In this way, the present invention uses one press instead of two presses as a two-step stroke consisting of an inner die and an outer die, and in the first stroke, the inner die presses the nozzle into the burring cylinder in a secondary manner. We have developed a press that can squeeze the cylindrical edge into the groove of the cylindrical edge with the outer die once with a stroke of .
