PURPOSE: An air damping mount is provided to implement a stopper function when a first insulator is excessively elastic-transformed, by coupling a second insulator to a center core. CONSTITUTION: An air damping mount comprises a center core(10), a first insulator(20), a first air hole(51), a bottom plate(50), a housing(30), a second insulator(40), and a second air hole(31). The first insulator is coupled to the center core in the upper part and recessed upward in the bottom. The bottom plate is coupled to the bottom of the first insulator to form a first chamber, and has the first air hole passing air in and out of the first chamber according to elastic deformation of the first insulator. A protruded hole is formed in the top of the housing and the first insulator is built in the housing. The second insulator is coupled between the housing and the center core capable of elastically deforming. The second air hole is formed in the housing passing the air in and out of a second chamber according to elastic deformation of the second insulator.
