摘要:
To expand a body weight adjustment range and achieve thinning. An initial position adjusting member 15 which can adjust initial resilient forces of two torsion bars 31, 41 is 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 unit 52 is provided such that a moving direction of a moving body coincides with an approximately perpendicular direction to a mutual displacement direction of an upper frame 10 relative to a lower frame 20, the thickness (height) of a fixed magnet unit 51 is 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 frame 10 has come closest to the lower frame 20 (a lower limit position) can be made thin.
