The invention provides a deceleration strip which comprises a fixing seat, wherein fixing mechanisms are arranged at two ends of the fixing seat; 3-6 support columns are arranged at the middle part of the fixing seat; a spring body and a cylinder are sequentially arranged on each support column from bottom to top; the upper ends of the cylinders are connected with the bottom of a curved plate; upper hook bodies are arranged at the bottom of the curved plate; lower hook bodies are arranged on the fixing seat and positioned in the same axial direction with the upper hook bodies; and the ends of the upper and lower hook bodies are rounded and smooth. The deceleration strip provided by the invention can effectively avoid the conditions that when a vehicle passes the deceleration strip, a torsion beam of the vehicle breaks because of too severe vibration and passengers in the vehicle feel uncomfortable.
