PURPOSE: A tube-shaped torsion beam for a rear suspension system of a vehicle is provided to have strength required for a torsion beam and improve the strength of a transition part. CONSTITUTION: A tube-shaped torsion beam for a rear suspension system of a vehicle comprises both ends(A), and a transition part(B). A tube-shaped reinforcing bar(30) formed to cover the both ends and the transition part is inserted into both sides of a main steel material(10). The main steel material is pressed and molded so that the both ends and the transition part are thicker than a central part(C). |
