PROBLEM TO BE SOLVED: To provide a torsion beam-type suspension that can improve durability while securing high roll rigidity.SOLUTION: A torsion beam-type suspension 1 comprises: a torsion beam 3 arranged to extend in a vehicle width direction; a pair of trailing arms 2 connected to both end parts in a shaft direction of the torsion beam 3; and a pair of reinforcing members (a first reinforcing member 4 and a second reinforcing member 5) arranged across the torsion beam 3 and each trailing arm 2 at both end parts in the shaft direction of the torsion beam 3 and fixed by welding to the torsion beam 3 and each trailing arm 2. In the torsion beam 3, at positions in the vicinities of tip parts (an inner tip part 401 and an inner tip part 501) inside a vehicle, of the reinforcing members (the first reinforcing member 4 and the second reinforcing member 5) are provided depressed parts 34 and 35 formed by depressing an outer surface 302 of the torsion beam 3.SELECTED DRAWING: Figure 2 |
