。 In a liquefied gas overfill prevention device that is installed in a liquefied gas tank and prevents overfilling of liquefied gas in conjunction with a float, a diaphragm and a pilot valve are separately provided, and one side of the diaphragm has an outlet opening in the center. A peripheral portion thereof is in contact with the annular inflow chamber, and the other side is in contact with the diaphragm chamber, and the outlet port and the annular inflow chamber are blocked by a valve seat wall, and the tip of the valve seat wall can be in contact with the diaphragm. The valve seat is annular, the diaphragm is biased away from the valve seat, the annular inflow chamber communicates with an inlet, and the annular inflow chamber and the diaphragm chamber are bored in a peripheral edge of the diaphragm. The overfill prevention device for liquefied gas is characterized in that the diaphragm chamber can be opened into the liquefied gas tank through a pilot valve interlocked with the float when the float is lowered. .
