Abstract
A seat structure includes a torsion bardisposed along the width direction, and an armwhich is connected to the torsion bar, enforced in the direction of falling backward at a normal state by the torsion barin the rear of a seat cushion, and disposed is a flat-type supporting memberbetween the supporting framesupported by the armand a frame member provided in front of the seat cushion, being strained by the elastic force of the torsion bar. Through this structure, the spring characteristic to give an influence on comfortability and riding comfort at the time of being seated can be given by the torsion bar, so that the number of coil springs which have been necessary in the vicinity of the body side can be reduced or the use of the coil spring can be stopped.
