PURPOSE: A device for reinforcing a torsion beam axle is provided to increase the durability span by reinforcing the torsion beam and decreasing the concentration of inner stress. CONSTITUTION: A first part(110) is reinforced by connecting a torsion beam of a rear wheel to an inner part through welding. The torsion beam(10) has a sharp shape in the opposite direction of direction connected with a trailing arm(12), and an upper side central part(111) is slantly round-shaped and is convex upward at a regular slant angle. A second part(112) is formed in a slant shaped from the first part(110) and has a smaller angle. A third part(114) deforms to have a flatten shape from a shape corresponding to the inner shape of the torsion beam and is connected to an inner face of the torsion beam by welding. A fourth part(116) is formed in a shape for spreading toward a part where the trailing arm is connected with the torsion beam form the third part and reinforces the outside of connection part between the torsion beam and the trailing arm.
