To provide an explosion-proof unmanned aircraft capable of preventing a machine body from becoming an ignition source in an explosion-proof area which has such a possibility that combustible gas exists.SOLUTION: An explosion-proof unmanned aircraft includes: a body which stores electric instruments therein; tubular fixed pipes which is fixed communicably with the inside and the outside of the body; propellers which generates a thrust; hollow tube-shaped arm pipes which support the propellers and through which cables of the propellers are made to pass, respectively; and sealing structures which are each provided inside the fixed pipe to seal the communication of the inside and the outside of the body. Further, the arm pipe is fixed in such a state as to be inserted to the fixed pipe. Furthermore, the body includes, in a predetermined range surrounding the fixed pipe, a thick part configured to have thickness thicker than thickness in other ranges.SELECTED DRAWING: Figure 6

    【課題】可燃性ガスが存在する可能性がある防爆エリアにおいて、機体が着火源となることを防止することのできる防爆無人航空機を提供する。【解決手段】防爆無人航空機は、電気機器を内部に収納するボディと、ボディの内外に通じるように固定された筒状の固定パイプと、推進力を発生させるプロペラと、プロペラを支持するとともにプロペラのケーブルが通される中空管状のアームパイプと、固定パイプの筒内に設けられ、ボディの内外の連通を封止する封止構造と、を備える。そして、アームパイプは、固定パイプに挿し込まれた状態で固定される。また、ボディは、固定パイプを囲む所定範囲に、肉厚が他の範囲の肉厚よりも厚くなるように構成された厚肉部を備えている。【選択図】図6
