Abstract
A torsion beam axle includes a torsion beam, a plurality of trailing arms made of a material different from that of the torsion beam, and connecting tubes made of a material better than that of the trailing arms with respect to weldability with the torsion beam, and integrally coupled to the trailing arms at one end part thereof, and welded to the torsion beam at the other end part thereof. Thereby, the coupling force between the trailing arms and the torsion beam made of different materials can be improved.
