STABILISER AND MANUFACTURING METHOD FOR PRODUCING SAME

A torsion portion (21) extending in a vehicle width direction and having a first cross-sectional area (S1), shoulder portions (22) located at both ends of the torsion portion (21) and having a second cross-sectional area (S2) larger than the first cross-sectional area (S1) and arm portions (23) extending from the shoulder portions (22) in a front and back direction of a vehicle, respectively and having the first cross-sectional area (S1), so that even when a hollow member is used for weight saving, can be realized by design and manufacturing method facilitating making uniform principal stress as in a solid member.
