To provide a seat support mechanism that is provided with a lifter, as well as is able to perform a cushion frame suspension function no matter to what height a cushion frame is adjusted. Torsion bars 330, 340 extending in the width direction of a cushion frame 10 and elastically supporting the cushion frame 10 are supported by a link mechanism 40 disposed between sliders 20 and the cushion frame 10. Even if the attitude of the link mechanism 40 is displaced when the lifter 30 adjusts the height, the positions of the torsion bars 330, 340 are displaced so as to follow the displacement. The torsion bars 330, 340 elastically support the cushion frame 10 no matter to what height the torsion bars are displaced. Thus, no matter to what height the cushion frame 10 is adjusted, the torsion bars 330, 340 are able to support the cushion frame 10 with predetermined elasticity and to exhibit predetermined vibration absorption characteristics.
