PROBLEM TO BE SOLVED: To simplify and miniaturize a device and prevent a start pump from sucking gasified gas when operation of the pump is changed over in a device supplying liquefied gas. SOLUTION: A tank 12 storing liquefied gas is enclosed by a heat insulating layer 18, and two pumps 14, 16 feeding liquefied gas in the tank are installed in the heat insulating layer 18. Suction pipes 24, 32 of the pumps 14, 16 are independently connected to the tank 12. Since the suction pipes are not commonized, gasified gas produced in a pump to be stopped is prevented from being sucked in the pump to be started when one pump is stopped and is switched to another pump.
