Document Type and Number:
Japanese Patent JP4714252
Kind Code:
B2
Abstract:
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.
