PROBLEM TO BE SOLVED: To provide an unmanned flight vehicle which prevents entry of foreign objects, such as water droplets and dust, into, in particular, a power unit to secure desired performance.SOLUTION: An unmanned flight vehicle of the invention includes: a fixed part having a motor housing 51 for housing a motor 50; and a rotary part which has a propeller shaft 53 supported so as to rotate relative to the motor housing 51 through a bearing 1 and integrally rotates with a propeller 30. Foreign object prevention means 10A which prevents entry of foreign objects into the interior of the motor housing 51 is provided at a facing part A where a fixed side component 51 forming the fixed part and a rotary side component 53 forming the rotary part face each other.SELECTED DRAWING: Figure 7
【課題】水滴や塵埃等の異物が特に動力部内に侵入することを防止して所望の性能を確保できる無人飛行体を提供する。【解決手段】本発明の無人飛行体は、モータ50を収容するためのモータハウジング51を有する固定部と、軸受1を介してモータハウジング51に対して回転可能に支持されるプロペラシャフト53を有し、プロペラ30と一体で回転する回転部とを備える。固定部を構成する固定側構成要素51と回転部を構成する回転側構成要素53とが対向する対向部Aには、モータハウジング51の内部に対する異物の侵入を防止する異物侵入防止手段10Aが設けられる。【選択図】 図7
