A sheet cushioning member includes front links coupled to a front torsion bar and rear links coupled to a rear torsion bar are arranged at a predetermined interval from each other in a front and rear direction of a seat, and when a predetermined load or larger is applied, the front links and the rear links rotate in opposite directions, and dampers are disposed to extend between lower portions of the front links and the rear links. When a predetermined load fluctuation or larger occurs, the dampers expand or contract to exhibit a damping force, and a load fluctuation smaller than this does not cause the dampers to expand or contract and is alleviated by elasticity of the front torsion bar and the rear torsion bar. An impact absorbing characteristic is thereby improved with a simple structure.
