PROBLEM TO BE SOLVED: To provide a hollow stabilizer such that flatness of a cross section of a bent part is suppressed.SOLUTION: A bent part 21 of a hollow stabilizer 10 bent by a stabilizer manufactured by a stabilizer manufacturing apparatus according to an embodiment has, with respect to cross sections in radial directions of a pipe: a first cross section part 41 within a range of 60-300° based upon 0° as the center; a second cross section part 42 within a range of 120-240° based upon 180° as the center; a third cross section part 43 formed within a range of 60 to less than 120° based upon 90° as the center; and a fourth cross section part 44 formed within a range of 240 to less than 300° based upon 270° as the center. The second cross section part 42 is smaller in curvature than the first cross section part 41. The third cross section part 43 and fourth cross section part 44 are smaller in curvature than the second cross section part 42, respectively.SELECTED DRAWING: Figure 3

    【課題】曲げ部の断面の偏平度が抑制された中空スタビライザを提供する。【解決手段】本実施形態のスタビライザ製造装置によって曲げられた中空スタビライザ10の曲げ部21は、パイプの径方向の断面に関し、0°を中心に60°から300°の範囲の第1の断面部41と、180°を中心に120°から240°の範囲内の第2の断面部42と、90°を中心に60°を越え120°未満の範囲内に形成された第3の断面部43と、270°を中心に240°を越え300°未満の範囲内に形成された第4の断面部44とを有している。第2の断面部42の曲率は第1の断面部41の曲率よりも小さい。第3の断面部43と第4の断面部44の曲率は、それぞれ第2の断面部42の曲率よりも小さい。【選択図】図3
