ントチユーブの開閉制御弁。[Scope of Claim for Utility Model Registration] A fuel sensor is installed near the filling port of a filler tube that supplies liquid fuel to the tank body to detect when a fuel gun is inserted into the filling port. The vent tube is equipped with an opening/closing control valve in which the valve body separates from the valve seat when receiving a detection signal from the refueling sensor and allows the fuel gas flowing through the vent tube to flow to the canister side during refueling. In this step, the valve body of the on-off control valve is moved upstream from the valve seat so that when the on-off control valve is inactive, it is pushed by positive pressure within the tank body and moves in the direction in which the on-off control valve closes. An opening/closing control valve for an automotive vent tube, characterized by the following:
