The invention provides a novel damper suitable for an automobile tail door electric push rod. The novel damper comprises a brake coupling, a brake outer sleeve, brake gaskets, a brake friction plate,a brake disc elastic piece and a brake threaded end cover, the brake outer sleeve, the brake gaskets, the brake friction plate, the brake disc elastic piece and the brake threaded end cover are arranged on the brake coupling in a sleeving fit mode, the inner space of the brake outer sleeve is of a structure with the wider upper portion and the narrower lower portion, the lower portion of the brakeouter sleeve is attached to the lower portion of the brake coupling, the two brake gaskets are located above the attaching portion between the brake coupling and the brake outer sleeve, the brake friction plate is arranged between the two brake gaskets, the brake disc elastic piece is arranged on the brake gaskets, and the brake threaded end cover is arranged on the brake disc elastic piece. Thenovel damper has the beneficial effects that the structure is simple and reasonable, the assembly efficiency is improved, the requirements of the assembly process and the height of the damper are reduced; and the strength of the structural material is relatively high, the service life is prolonged, and the universality of the product is improved.
