Abstract
A torsion beam of a vehicle torsion beam suspension has a closed cross section. A beam center portion has an inverse substantially v-shaped cross section or a substantially v-shaped cross section. Circumference increasing portions having a longer circumferential length toward the beam ends are disposed at opposite sides of the beam center portion. Each circumference increasing portion has a beam width that is a width in the fore and aft direction of a vehicle body, the beam width gradually increasing toward a beam end, and increasing at a higher rate as a position of the beam width is closer to the beam end.
