PROBLEM TO BE SOLVED: To provide a fitting structure of a blade which can be loaded on a light truck without protruding from a load-carrying platform and can be located and stored in a narrow space in a warehouse without disassembly of an unmanned helicopter.SOLUTION: A fixation bolt is inserted between upper and lower grips of a blade holder 6 in which a root part of a blade 5 is inserted thereby holding the root part of the blade 5, and the blade 5 is rotatably fitted to the blade holder 6 with the fixation bolt as a support shaft. A lock pin 16 is so provided between the upper and lower grips of the blade holder 6 that the pin is freely capable of advancing and retracting and the advanced lock pin 16 can be inserted into a hole 7a of the blade 5. At an inserted position, the blade 5 is fixed between the upper and lower grips, the lock pin 16 is removed from the hole 7a by an operation for retracting the lock pin 16 thereby releasing fixation of the blade 5, and the blade 5 is rotated with the fixation bolt as a support shaft and folded.SELECTED DRAWING: Figure 5

    【課題】無人ヘリコプタの機体を分解することなく、荷台からはみ出させずに軽トラックに積載したり、倉庫内の狭小なスペースに設置して保管したりすることができるブレード取り付け構造を提供する。【解決手段】ブレード5の根元部が挿入されたブレードホルダー6の上下のグリップ間に固定ボルトを挿通してブレード5の根元部をグリップ間に保持し、且つ固定ボルトを支軸としてブレード5を回転自在にブレードホルダー6に取り付ける。ブレードホルダー6の上下のグリップ間にロックピン16を進退自在に、且つ進出移動したロックピン16がブレード5の穴部7aに挿入可能に設置し、挿入位置でブレード5を上下のグリップ間に固定し、ロックピン16を後退させる操作でロックピン16を穴部7aから外してブレード5の固定を解除し、固定ボルトを支点としてブレード5を回転させて折り畳む。【選択図】図5
