11. The compressor mounting device of claim 1 , wherein an opening hole is formed in the main body along a length direction, the length direction of the main body being a direction between the first and second frame mounting units.

12. The compressor mounting device of claim 1 , wherein the main body is formed with a “T” shape through the first frame mounting unit.

13. The compressor mounting device of claim 1 , wherein the first frame mounting unit is mounted through a bracket provided on the vehicle body frame.

14. A compressor mounting device for mounting a compressor to a vehicle body frame, the compressor mounting device comprising:

a main body to be mounted to the vehicle body frame through first and second frame mounting units that are integrally formed to one end of the vehicle body frame and the other end of the vehicle body frame, the main body including first and second compressor mounting units formed to be protruded upwardly between the first and second frame mounting units so as to be mounted to first and second lugs formed in the compressor;

a main bush unit mounted to the first and second compressor mounting units and connecting the compressor and the first and second compressor mounting units through the first and second lugs to lessen vibration generated from the compressor from being transmitted to the vehicle body frame through the main body; and

a sub-bush unit mounted to the first and second frame mounting units or the vehicle body frame and connecting the vehicle body frame and the main body to reduce an impact transmitted from the vehicle body frame to the compressor through the main body;

wherein the main bush unit comprises:

an outer ring mounted to the first and second compressor mounting unit;

a first insulator with an exterior circumference vulcanized-bonded to an interior circumference of the outer ring; and

an inner stud with the exterior circumference vulcanized-bonded to the center of the first insulator and engaged to the first or second lug.
