Claims

[Scope of utility model registration request]

An inner tube protrudes from the end face of the vacuum outer tube, surrounds the outside of the double tube made up of the inner tube and the vacuum outer tube, and is provided with a sealing mechanism between the inner tube and the vacuum outer tube so as to be movable relative to the vacuum outer tube. A second outer tube is provided, and a valve seat is provided at the lower end of the second outer tube in contact with the lower end of the inner tube and communicates with the thin tube, and when the valve seat is separated from the inner tube, the liquefied gas flows between the inner tube and the inner tube. In the transfer pipe, in which a plurality of holes are bored in the valve seat and the upper part of the second outer pipe is attached to the tank inlet to communicate the thin pipes, a plurality of holes are formed in the second outer pipe at a position inside the tank. A liquefied gas transfer pipe, characterized in that a small hole and a cutoff valve mechanism that closes when the tip of the inner pipe and the valve seat are separated are provided in the lower part of the small hole.
