To provide a tank truck capable of preventing fluid from flowing out from an unintended place during switching.SOLUTION: A tank truck includes: a first flow path R1 for discharging a liquid from a tank 5 for storing liquids or sucking in a liquid into the tank 5; a second flow path R2 that guides the liquid from the first flow path R1 to a discharge unit for discharging the liquid; a third flow path R3 for sucking in a liquid stored in a storage unit separate from the tank 5; a switching valve 9 to which the first flow path R1, the second flow path R2, and the third flow path R3 are connected; a control unit that switches the switching valve 9 between a state in which the first flow path R1 and the second flow path R2 communicate with each other so that the liquid in the tank 5 moves to the discharge unit and a state in which the third flow path R3 and the first flow path R1 communicate with each other so that the liquid in the storage unit moves to the tank 5. A second on-off valve 26 that can be opened and closed is installed in the second flow path R2. A third on-off valve 30 that can be opened and closed is installed in the third flow path R3.SELECTED DRAWING: Figure 2

    【課題】切替中に意図していないところから流体が流出してしまうことを防止することができるタンク車を提供する。【解決手段】液体を積載するタンク5内の液体を排出する、又はタンク5内へ液体を吸入する第1の流路R1と、第1の流路R1からの液体を吐出する吐出部へ案内する第2の流路R2と、タンク5とは別の貯留部内に貯留されている液体を吸入する第3の流路R3と、第1の流路R1と第2の流路R2と第3の流路R3とが接続される切替弁9と、タンク5内の液体が吐出部へ移動するように第1の流路R1と第2の流路R2とが連通する状態と貯留部内の液体がタンク5へ移動するように第3の流路R3と第1の流路R1とが連通する状態とに切替弁9を切り替え操作する制御部と、を備え、第2の流路R2に開閉可能な第2の開閉弁26を設けるととともに、第3の流路R3に開閉可能な第3の開閉弁30を設けた。【選択図】図2
