There are improved a vibration absorption characteristic and a impact absorption characteristic. In a seat suspension mechanism (1) of the present invention, an intermediate frame (300) is supported through a first link mechanism (130) by a base frame (100), and a seat support frame (200) is supported through a second link mechanism (230) by the intermediate frame (300). A first spring mechanism (140) which elastically biases the intermediate frame (300) and a second spring mechanism (240) which elastically biases the seat support frame (200) are included, and meanwhile, a damper (150) is suspended between the base frame (100) and the seat support frame (200) excluding the intermediate frame (300). Phases with respect to vibrations differ between the seat support frame (200) on which damping force of the damper (150) acts directly and the intermediate frame (300) on which a characteristic of the damper (150) does not act directly, which makes it possible to exhibit high vibration absorption characteristic and impact absorption characteristic.
