To make it possible to prevent flight from stopping when a flight body moving in a vertical direction is brought into contact with an object.SOLUTION: A propeller guard 11 surrounds propellers 27 of a flight body 13 including: at least three pieces of horizontal ribs 17 extending in a radial direction from a body 15; outermost annular ribs (second outermost annular ribs 21) respectively connecting the tip ends of the horizontal ribs 17; a motor 25 which is fixed to the horizontal ribs 17 and has the propellers 27 fixed to an almost vertical driving shaft thereof; and connected annular ribs 53 disposed to the body 15 on the upper side in a vertical direction. The propeller guard is provided with a bumper 55 which is disposed in a radial direction around the connected annular ribs 53, has an upper end part 57 fixed to the connected annular ribs 53, and a lower end part 59 fixed to the outermost annular ribs, and has the inclination angle gradually increased toward the outermost annular ribs from the connected annular ribs 53.SELECTED DRAWING: Figure 2

    【課題】鉛直方向に移動している飛行体が物体に接触した際に飛行が停止することを抑制できる。【解決手段】本体15から放射方向に延出する少なくとも3本以上の水平リブ17と、水平リブ17の先端を連結する最外環リブ(第2最外環リブ21)と、水平リブ17に固定されて略鉛直方向の駆動軸にプロペラ27が固定されるモータ25と、本体15に対し鉛直方向上側に配置される連結環リブ53と、を備える飛行体13のプロペラ27を囲うプロペラガード11であって、連結環リブ53を中心に放射方向に配置され、連結環リブ53に上端部57が固定されるとともに下端部59が最外環リブに固定され、連結環リブ53から最外環リブに向かって傾斜角度が徐々に大きくなるバンパー55を備える。【選択図】図2
