Abstract: A torsion beam is configured in an arch shape and comprised of an open cross-section member including an arch lower-half portion and an arch upper-half portion. A sectional shape of the arch lower-half portion in a cross section perpendicular to a longitudinal direction of the arch lower-half portion is configured to be substantially horizontal when a vehicle is in a standard state, and a central portion, in the vehicle width direction, of the torsion beam is configured such that a front edge portion of the arch lower-half portion and a front edge portion of the arch upper-half portion are located substantially at the same position in a vehicle longitudinal direction when the vehicle is in a full-rebound state. Thereby, the rigidity and the productivity can be endured, attaining low floor-level of the vehicle.
