PURPOSE: A moving tube trailer for charging of a compressed natural gas vehicle is provided to prevent waste of unnecessary travel, and to cut down cost for a gas station by supplying fuel to the vehicle on the spot with moving the moving tube trailer into the vehicle. CONSTITUTION: A tube trailer stores, transports and charges compressed natural gas. A tube(2) of the tube trailer is installed in a skid(1), and a safety valve is combined with the tube in the front of the skid. A manifold mounting the safety valve, a pressure gauge, a drain valve and a ball valve is installed in the rear part of the skid. The moving tube trailer charges compressed natural gas to the vehicle at high pressure, middle pressure, or low pressure stage. A charger is connected to the tube trailer through a high pressure hose to fill the vehicle with gas, and fuel fillers are formed in the lower center of the rear part of the tube trailer.
