To protect a wing door.SOLUTION: A wing opening/closing device has a first hydraulic cylinder which is fitted to a first end of a wing door and comprises a first open-side oil chamber, and a second hydraulic cylinder which is fitted to a second end of the wing door and comprises a second open-side oil chamber. The wing opening/closing device has a shunt valve which is connected to a discharge oil passage of a hydraulic pump, connected to the first open-side oil chamber through a first oil passage, and connected to the second open-side oil chamber through a second oil passage. The wing opening/closing device has a relay which is provided at a power supply circuit for an electric motor driving the hydraulic pump, and operates between a connection state for supplying electric power to the electric motor and a disconnection state for cutting off the power supply. The relay operates from the connection state to the disconnection state if the working hydraulic pressure in the first oil passage exceeds a threshold with the wing door opened.SELECTED DRAWING: Figure 4

    【課題】ウイング扉を保護する。【解決手段】ウイング開閉装置は、ウイング扉の第1端部に取り付けられて第1開側油室を備える第1油圧シリンダと、前記ウイング扉の第2端部に取り付けられて第2開側油室を備える第2油圧シリンダと、を有する。前記ウイング開閉装置は、油圧ポンプの吐出油路に接続され、前記第1開側油室に第1油路を介して接続され、前記第2開側油室に第2油路を介して接続される、分流バルブを有する。前記ウイング開閉装置は、前記油圧ポンプを駆動する電動モータの電源回路に設けられ、前記電動モータに通電する接続状態と通電を遮断する切断状態とに作動するリレーを有する。前記リレーは、前記ウイング扉が開かれる状況のもとで、前記第1油路内の作動油圧が閾値を上回る場合に、前記接続状態から前記切断状態に作動する。【選択図】図4
