To provide a folding hook structure for putting a first component and a second component which are rotatable relative to each other into an extended state or a folded state.SOLUTION: A folding hook structure includes: a rotating disk provided with a folding hook groove on the disk surface thereof; a folding hook which is inserted in the folding hook groove and movable between a locked position and a released position along the folding hook groove; and a sliding member movable between an extended position close to the rotating disk and a retracted position away from the rotating disk along the radial direction of the rotating disk. The folding hook groove includes: a circumferential direction section extending in the circumferential direction of the rotating disk with the rotation center of the rotating disk as a circle center; and a radial direction section extending from the circumferential direction section in the radial direction of the rotating disk. A first component and a second component are put into an extended state when the folding hook is located in the circumferential direction section, and are put into a folded state when the folding hook is located in the radial direction section.SELECTED DRAWING: Figure 5B
【課題】相対回転可能な第1部品及び第2部品を展開状態又は折り畳み状態にするための折り畳みフック構造の提供。【解決手段】折り畳みフック構造は、盤面に折り畳みフック用溝が設けられる回転盤と、前記折り畳みフック用溝に挿入され、前記折り畳みフック用溝に沿ってロック位置と解放位置との間で移動可能である折り畳みフックと、前記回転盤に近づく伸出位置と前記回転盤から離れる退避位置との間で前記回転盤の径方向に沿って移動可能なスライド部材と、を含み、前記折り畳みフック用溝は、前記回転中心を円の中心として前記回転盤の周方向に伸びる周方向区間と、前記周方向区間から前記回転盤の径方向に伸びる径方向区間と、を含み、前記第1部品及び前記第2部品は、前記折り畳みフックが前記周方向区間に位置する場合、展開状態になり、前記折り畳みフックが前記径方向区間に位置する場合、折り畳み状態になる。【選択図】図5B
