The invention relates to a time delay cavity spring for an automobile seat. The time delay cavity spring comprises a sliding plug cylinder, a cylinder plug and a spring packaged and pressed in an inner cavity of the sliding plug cylinder through the cylinder plug. The time delay cavity spring is characterized in that the sliding plug cylinder and the cylinder plug are arranged in a sealed mode; air holes are formed in the cylinder plug and allow the interior and the exterior of the inner cavity to be communicated, a groove block with a hemispheric groove is arranged below the sliding plug cylinder, and a hemispheric structure is arranged at the lower portion of the sliding plug cylinder and matched with a hemispheric groove structure. According to the time delay cavity spring, due to the fact that air needs to go in and out of the air holes in the contractive pressing and popping unfolding processes, certain time is needed for air to go in and go out, shockproof vibration frequency is determined by air pressure and the spring property without being only determined by the internal spring property of the spring due to air pressure inside the cavity, the shockproof vibration frequency slows down to a certain degree and is not regular, resonance is not caused, and uncomfortable vibration frequency with long duration is not caused to the human body.
