Abstract
A fuel tank valve device equipped with a casing, and a valve mechanism. The valve mechanism has a first valve unit having a first valve connecting hole, and a second valve unit that opens and closes the first valve connecting hole. The first valve unit completely closes the valve flow path by moving by the force in the valve closing direction when the pressure of the second communication path exceeds a preset first pressure value. In a state when the first valve unit is closing the valve flow path, when the pressure of the second communication path exceeds a preset second pressure value that is greater than the first pressure value, the second valve unit receives the pressure from the first valve connecting hole and moves to open the first valve connecting hole, communicating with the valve flow path.
