The invention discloses a damper for a lifting rod of an automobile trunk. The damper comprises a shell; the shell is internally provided with an input shaft, an inner core, an outer core and an output shaft; the upper end of the inner core is inserted into the outer core; the lower end of the output shaft is sequentially inserted into the outer core and the inner core; the upper end of the input shaft is sequentially inserted into the inner core and the output shaft; the upper end of the input shaft is connected with the lower end of the output shaft through a screw; the outer wall of the inner core is sleeve with an inner core spring, and the inner core spring makes contact with the inner wall of the outer core; the outer wall of the outer core is sleeved with an outer core spring, and the outer core spring makes contact with the inner wall of the shell; the inner core spring is squeezed to be expanded through the output shaft, the jacking force of the inner core spring to the inner wall of the outer core is increased, then, the outer core and the inner core are driven to rotate in sequence, and the effect that reduced power is transmitted into the input shaft is achieved. The damper is reasonable in overall structural design, high in stability and capable of providing appropriate resistance for the stretching out and drawing back processes of the lifting rod, so that a door of the trunk is opened or closed with appropriate strength, and opening and closing are more convenient and quicker.
