To provide an unmanned flight body having improved quietness.SOLUTION: An unmanned flight body 1 has: a housing 2 which is configured from a bottom plate member, a ceiling member, and a wall member which connects the vicinity of the bottom plate member and the vicinity of the ceiling member; plural arm parts 8 which extends outward from the housing 2; and a motor 10 which is located at an end part at a free end side of the arm part 8 and rotates a propeller 12. The unmanned flight body 1 has an intermediate member which is located between the motor 10 and an end part 8a of the arm part, and reflects and/or absorbs oscillation due to rotation of the motor 10. The arm part 8 is formed from a material with prescribed oscillation damping performance, and a principal surface of at least one of the bottom plate member and the ceiling member is divided into plural portions, thereby improving quietness.SELECTED DRAWING: Figure 1
【課題】静粛性を向上した無人飛行体を提供する。【解決手段】無人飛行体1は、底板部材、天井部材、及び、底板部材の周縁部近傍と天井部材の周縁部近傍を接続する壁部材と、で構成される筐体2と、筐体2から外側へ延在する複数の腕部8と、腕部8の自由端側の端部に配置される、プロペラ12を回転させるためのモーター10と、を有する。無人飛行体1は、モーター10と腕部の端部8aの間に配置され、モーター10の回転に起因する振動を反射及び/または吸収する中間部材を有し、腕部8は所定の振動減衰能を有する材料で形成されており、底板部材及び天井部材の少なくとも一方の主面は、複数の部分に区分されており、これにより、静粛性を向上する。【選択図】図1
