The invention provides a rubber sealing strip used for an outer protective plate of an automobile door. The rubber sealing strip used for the outer protective plate of the automobile door is composed of a middle plate-shaped supporting portion, a first insertion claw portion, a second insertion claw portion and an outer arc protruding portion. The two insertion claw portions are located on the two sides of the plate-shaped supporting portion respectively, and the outer arc protruding portion is located on the two sides of the plate-shaped supporting portion. The rubber sealing strip is characterized in that a multi-body co-extrusion forming technology is adopted by the rubber sealing strip, and the hardnesses of the two insertion claw portions, the hardness of the plate-shaped supporting portion and the hardness of the outer arc protruding portion become smaller gradually. According to the rubber sealing strip, the hardnesses of the materials of different portions are adjusted by utilizing the multi-body co-extrusion technology, the two insertion claw portions have high hardness, so that the tension of the two insertion claw portions in the installation groove become larger, enough anti-disengagement strength is guaranteed, curling deformation caused in the assembly process is reduced, the assembly speed is increased, it is guaranteed that the rubber sealing strip can be installed in place, and the assembly quality is improved; the plate-shaped supporting portion has the moderate hardness, and therefore ineffectiveness caused by deformation of the sealing strip is avoided; the hardness of the outer arc protruding portion is low, so that the fit performance between the outer arc protruding portion and a metal plate of a door frame is improved, and therefore the leakproofness between the automobile door and the door frame is improved.
