A twist beam (10) is made from a tube, having a short circumferential end face in the middle section of the shape "V" or "U" cross-section has a longer circumference at the beam ends 14,16. Accordingly, the specification proposes to use a tubular member having a predetermined length. The tubular member is deformed in a "V" or "U" shape in the central section of the tube, it is then expanded at both ends. This structure is formed using a closed die internal pressure forming process, for example hydraulic forming or blow molding and the like. End of the tubular member may have a substantially elliptical cross-section or of square. The tubular member of the present disclosure may be heat treatment inside a closed die molding process in order to obtain a higher material strength. In this manner, the twisted beam in the present description is optimized to preferably use at least a cross-section over its entire length and, as a result, substantially can be further manufactured at a lower cost by substantially using less material has a small mass as .
