There are improved a vibration absorption characteristic and an impact absorption characteristic. A seat suspension mechanism (1) of the present invention is set so that links (131, 132) of a first link mechanism (130) on a base frame (100) side and links (231, 232) of a second link mechanism (230) on a seat support frame (200) side, between which an intermediate frame (300) is put, differ in operating angles, that is, so that the links (231, 232) of the second link mechanism (230) operate in the range of an angle closer to a vertical to a front-rear direction of a vehicle body. This allows front-rear movement of the seat support frame (200) through the second link mechanism (230) to mainly respond to input vibrations of front-rear movement to thereby improve a vibration absorption characteristic and an impact absorption characteristic in the front-rear direction.
