PURPOSE: A cryogenic vessel is provided to improve insulation property by vacuously charging perlite between an inner vessel and an outer vessel, to prevent the breakage of the inner and outer vessels by removing the relative displacement of the inner vessel and the outer vessel, and to improve safety and convenience in use by supporting a cryogenic vessel on a pallet. CONSTITUTION: An inner vessel(1) is installed in an outer vessel(3). The space between the inner vessel and the outer vessel is vacuumed by the super insulation technique. An inner vessel support for supporting the inner vessel is installed between an inner vessel lower head(4) and the inner bottom surface of the outer vessel. A perlite insulating material(6) is vacuously charged in the space between the inner vessel and the outer vessel. An outer vessel seat(7) is attached to the outer lower portion of the outer vessel. The outer vessel seat is supported on a lower supporter of a pallet(8). Many shock absorbers(21) for protecting the inner vessel and the outer vessel are installed on the pallet.
