  • Patent number: 11161385
    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.

  • Patent number: 10266029
    Abstract: A semi-finished product (31) includes a first curved portion on one end of a plate-shaped bridge portion (33), and a second curved portion (37) on the other end of the bridge portion (33). The second curved portion (37) includes at the end a second lock portion (51) to lock with a first lock portion (41). The bridge portion (33) and the inner circumferential surfaces of the first and second curved portions (35, 37) are pressure-contacted and caulked on the outer circumferential surface of the stabilizer bar (11) by first and second dies (61, 62). At least one of the inner circumferential surfaces (31c) of the first and second curved portions (35, 37) and the outer circumferential surface of the stabilizer bar opposed to the inner surfaces (31c) is formed with an anti-slippage portion (38). The inner circumferential surfaces (31c) of the first and second curved portions (35, 37) and the outer circumferential surface of the stabilizer bar (11) have an anti-slippage material (Co) therebetween.
