Abstract: A hollow stabilizer includes a curved part having eight regions defined in a cross section. A first region includes a 90° first part when the center of the inside of the curve is taken to be at 0° and the center of the outside of the curve is taken to be at 180°. A third region includes a 0° third part. A fifth region includes a 270° fifth part. A seventh region includes a 180° seventh part. The radii of curvature of the respective outer surfaces of the third part and the seventh part are larger and the radii of curvature of the respective outer surfaces of the second part and the sixth part are smaller than the radii of curvature of the respective outer surfaces of the fourth part and the fifth part.

Abstract: A stabilizer is provided with a restriction ring connected to a torsion portion at a connection portion adjacent to a bush. The restriction ring has a body, a female portion, a male portion, and a welded portion. The female portion has gripping portions with a spacing therebetween decreasing in the direction away from a valley bottom portion. The male portion has a neck portion, an expansion portion, and a contraction portion. The welded portion covers at least the range of the contraction portion and the valley bottom portion and melts in the plate thickness direction from the outer peripheral surface.

Abstract: A stabilizer link includes a support bar, and ball joints. The ball joint includes a ball stud including a ball portion and a stud portion, and a housing that turnably supports the ball portion of the ball stud. The stabilizer is formed of a rod-shaped member made of metal. Mounting portions to which the stabilizer links are to be joined are respectively provided at both ends of the stabilizer. Through-holes through which the stud portions of the ball studs are to be inserted are respectively provided in the mounting portions. The stabilizer link is joined to the stabilizer by press-fitting the stud portion of the ball stud into the through-hole of the mounting portion.
