The invention relates to a bumping-resistant cylinder spring for an automobile seat. The bumping-resistant cylinder spring for the automobile seat comprises a sliding plug cylinder, a cylinder plug and a spring body sealed and pressed in the inner cavity of the sliding plug cylinder through the cylinder plug. The cylinder plug is provided with an air hole so that the interior of the inner cavity and the exterior of the inner cavity can be communicated. The air hole is provided with a small-end-up wedged hole is formed in the air hole. The lower portion of the wedged hole is sealed by a net body so that a hole cavity can be formed. A polyhedral-structure plugging block is arranged in the hole cavity, and the size of the plugging block is larger than the radial size of the upper portion of the wedged hole. According to the spring, due to the fact that air needs to enter or leave the wedged hole in the compressing and rebounding process, the air needs certain time to enter or leave the wedge hole; thus, because of air pressure in the cavity, the vibration frequency of a shock absorber is not determined only by the nature of the inner spring, but is determined by the air pressure and the nature of the spring; and the vibration frequency of the shock absorber becomes low to a certain extent and is not regular any more, and accordingly no resonance is caused, and long-time vibration frequency making human bodies uncomfortable is not caused, either.
