PROBLEM TO BE SOLVED: To provide a tank truck capable of supplying liquefied gas without emitting compressor working noises around a liquefied gas storage tank of a customer. SOLUTION: When delivered to a customer, first a liquefied gas 7 is transferred from a master tank of a gas sale firm, etc., to a liquefied gas tank 1 on the tank truck. When the tank truck starts running for the customer, a compressor 3 is operated with the power of the tank truck engine so as to pressurize a pressure tank 2. When the tank truck has reached the customer, the operator couples a liquefied gas supplying piping 6 with the liquefied gas storage tank of the customer and opens a first 4 and second valves 5. At this time, the pressure tank 3 is put in communication with the liquefied gas tank 1 to cause inside the liquefied gas tank 1 to be pressurized, and the liquefied gas 7 is sent by pressure and supplied to the storage tank of the customer.
