A tank sealing valve arranged in a passage network through which a fluid flows between a fuel tank and a canister includes a first valve unit and a second valve unit. A first port and a second port of three ports included in an outer case body of the first valve unit are open toward a first chamber of two chambers divided by a diaphragm or a bellows of the first valve unit, and a third port of the three ports is open toward a second chamber of the two chambers. A valve body of the first valve unit includes a through passage penetrating a valve portion and a column portion of the valve body. The valve portion communicates with the first port and the second chamber through the through passage in a case where the first port is closed. The second valve unit opens and closes the third port.
