There is provided a stabilizer bar in which through holes are not positionally offset even if the attachment portions are bent after the through holes are formed therein. A stabilizer bar is composed of a steel pipe material bent to an approximate U- shape and has attachment portions formed by deforming the free ends of the steel material in a flat plate shape. Through holes are formed in the attachment portions to fix them to a vehicle body, and each of the attachment portions has a cross section configured as a three-layer structure that is partitioned by first and second overlapping surfaces of a folded hollow portion. That is, the three-layered structure is composed of an upper layer portion positioned on the first overlapping surfaces, an intermediate layer portion positioned between the first and second overlapping surfaces, and a lower layer portion positioned under the first overlapping surfaces. Here, the first and second overlapping surfaces are disposed such that the cross section thereof is formed in an X-shape.

L'invention porte sur un stabilisateur creux, dans lequel, même si le de stabilisateur creux est incurvé avec un trou traversant formé dans une section de montage, la position du trou traversant ne change pas. Un stabilisateur creux (10) est formé sous une forme sensiblement en U par courbure d'une ébauche de tuyau en acier, et une section de montage (18) écrasée sous une forme de type plaque plate est formée à l'extrémité avant du stabilisateur creux. Un trou traversant (20) pour fixer la section de montage (18) sur une carrosserie de véhicule est disposé dans la section de montage (18). La section de montage (18) possède une forme de section transversale ayant une structure en trois couches divisée par des surfaces superposées (36, 38) d'une section creuse pliée. Autrement dit, la structure en trois couches est composée d'une partie de couche supérieure (42) située au-dessus de la surface superposée (36), d'une partie de couche intermédiaire (44) située entre la surface superposée (36) et la surface superposée (38), et d'une partie de couche inférieure (46) située en dessous de la partie superposée (38). La surface superposée (36) et la surface superposée (38) forment une forme de X en section transversale.
