A seat structure includes a torsion bar 40 disposed along the width direction in the vicinity of the bottom end of a back frame 20, a pelvis supporting plate 50 is connected to the torsion bar 40, and a flat-type supporting member 60 for the seat back is engaged with the vicinity of the bottom end of the pelvis supporting plate 50 and strained. Slack of the flat-type supporting member 60 can be eliminated by the pelvis supporting plate 50 to enhance the appearance.
