The invention relates to a car seat shock absorber rotating chamber spring device. The car seat shock absorber rotating chamber spring device 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 and the two chamber springs are separated and arranged in parallel. Hemispherical structures can buffer force coming from a tilting direction on a seat and can guarantee the chamber springs to have certain radial rotation flexibility, the lower free ends of sliding plug cylinders are restricted in hemispherical grooves and do not run out of the groove blocks due to excessive great vibrating amplitude, the tilting of a shock absorber integral body is facilitated and the car seat plate flexibility is guaranteed; when the seat plate tilts to the direction of one chamber spring, the corresponding spring is compressed, the spring on the other side can produce certain restoring force through the tensile force of the spring and thus the tilting extent of the seat plate is reduced.
