The invention relates to a chamber spring type seat shock absorber. The chamber spring type seat shock absorber comprises a seat plate at the upper part and two groove blocks at the lower part, wherein two chamber springs are arranged between the seat plate and the groove blocks, the two groove blocks are slidably connected onto a bottom plate, each chamber spring is provided with an upper cover and a lower cover which are buckled together, a spring is arranged in a chamber jointly formed by the upper cover and the lower cover, the upper end of the upper cover is rotatably connected with the seat plate, the lower end of the lower cover is rotatably connected with the corresponding groove block, the two chamber springs are obliquely arranged in a splayed structure, and the two groove blocks are in stretchable connection through a spring. The two chamber springs which are arranged in the splayed structure can guarantee that the seat plate can move up and down when the force in the vertical direction of the seat plate changes, and the displacement of the movement comes from the change of the angle between the two chamber springs which are arranged in the splayed structure and also comes from the change of the lengths of the chamber springs; the spring between the groove blocks favorably guarantees that the chamber springs do not fully tilt and can always provide restoring force for the change of the angle of the splayed structure, and thus elastic buffer is provided for the upward and downward displacement of the seat.
