The invention discloses a transfer box structure suitable for a small aeroengine. The transfer box structure suitable for the small aeroengine comprises a base, a shell and an engine support structure, wherein the shell is mainly applied to the engine and provides a holding space for the engine; the engine support structure arranged on the upper surface of a support bottom plate is mainly used forsupporting the engine through a vibration isolation way and transmitting the mass of the engine onto the base; and the base is mainly used for supporting a whole transfer box. The transfer box structure provided by the invention is simple and convenient to process, has favorable conveying characteristic and hoisting characteristic, considers the characteristics of antivibration and rainproofnessin the conveying process, is light in mass and less in space occupation, and has the characteristics of safety and high efficiency.
