A valve device for fuel tank has a case having an air flow valve orifice connected to outside of the tank at an upper part and a fuel inflow part beneath this air flow valve orifice, and being divided into an upper chamber and a lower chamber by a partition formed between the air flow valve orifice and the inflow part; an upper float body being inside the upper chamber and ascending by fuel flowing into the case to be seated in the air flow valve orifice; and a lower float body being supported inside the lower chamber of the case with an upwardly projecting guide shaft being inserted to be movable vertically inside an insertion part formed on the partition, and ascending by fuel flowing into the case to close a main connect-through part between the lower chamber and the upper chamber formed on the partition. A receiving hole for receiving the guide shaft of the lower float body is provided on the upper float body.
