To highly accurately detect a state of fluid transported by a fan along a flow path, or a state of structure through which fluid passes.SOLUTION: A fluid transport device comprises: a fan that transports fluid along a flow path through a rotational motion; a structure provided in the flow path, which causes pressure loss in the flow path when the fluid passes through the structure; and a detection unit that monitors a phenomenon correlated to variation in force that blades of the fan receives from the fluid due to disturbance of the fluid transported by the fan along the flow path, to detect a state of the fluid or a state of the structure.SELECTED DRAWING: Figure 5 【課題】流路に沿ってファンにより搬送される流体の状態又は前記流体が通り抜ける構造物の状態を高精度に検出すること。【解決手段】流路に沿って流体を回転運動により搬送するファンと、前記流路に設けられた構造物であって、前記流体が前記構造物を通り抜けることで前記流路内に圧力損失を発生させる構造物と、前記流路に沿って前記ファンにより搬送される前記流体の擾乱により前記ファンの羽根が前記流体から受ける力の変動に相関する現象を監視して、前記流体の状態又は前記構造物の状態を検出する検出部と、を備える、流体搬送装置。【選択図】図５
