To provide a vibration control structure of an unmanned aircraft which enables reduction of an impact input to an unmanned aircraft during landing of the unmanned aircraft to inhibit overturning and damage of the unmanned aircraft.SOLUTION: A vibration control structure reduces an impact input to a leg part of an unmanned aircraft during landing of the unmanned aircraft and includes: a rubber leg 41 which is attached to the leg part 21 and elastically deforms to reduce the impact when the impact is input; and an air spring which compresses air enclosed in an internal space 47 of the rubber leg 41 when the impact is input to reduce the impact. The leg part 21 includes: a fixed leg part 31 which is fixed to an airframe body and holds the rubber leg 41; and a movable leg part 51 which is connected to a lower end part of the fixed leg part 31 so as to be slidable in a vertical direction. The movable leg part 51 includes a rubber leg contact part 53 disposed below the rubber leg 41.SELECTED DRAWING: Figure 2

    【課題】無人航空機の着陸時に無人航空機に入力する衝撃を低減することができ、もって無人航空機が転倒したり破損したりするのを抑制する。【解決手段】無人航空機の着陸時に無人航空機の脚部に入力する衝撃を低減する防振構造であって、脚部21に取り付けられ、衝撃入力時に弾性変形することにより衝撃を低減するゴム足41と、ゴム足41の内部空間47に封入する空気を衝撃入力時に圧縮することにより衝撃を低減する空気ばねとを備える。脚部21は、機体本体に固定され、ゴム足41を保持する固定脚部31と、固定脚部31の下端部に上下方向スライド可能に連結された可動脚部51とを備える。可動脚部51は、ゴム足41の下方に配置されるゴム足接触部53を備える。【選択図】図2
