Abstract
There are improved a vibration absorption characteristic and an impact absorption characteristic. A seat suspension mechanism set so that links of a first link mechanism on a base frame side and links of a second link mechanism on a seat support frame side, between which an intermediate frame is put, differ in operating angles, that is, so that the links of the second link mechanism 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 through the second link mechanism 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.
