Abstract
To expand a body weight adjustment range and achieve thinning. An initial position adjusting memberwhich can adjust initial resilient forces of two torsion barsis provided. Therefore, a body weight adjustment range is expanded as compared with a conventional configuration where a resilient force of only one torsion bar is adjusted. Since a moving magnet unitis provided such that a moving direction of a moving body coincides with an approximately perpendicular direction to a mutual displacement direction of an upper framerelative to a lower frame, the thickness (height) of a fixed magnet unitis made thin as compared with a case where the moving magnet unit is provided such that the moving direction of the moving body coincides with approximately the same direction as the mutual displacement direction of the upper frame relative to the lower frame, so that the thickness of the whole seat suspension at a position at which the upper framehas come closest to the lower frame(a lower limit position) can be made thin.
