PROBLEM TO BE SOLVED: To provide a container for storing a liquefied gas which can withstand shocks and vibrations even under an extremely low temperature and also has high thermal insulation effects. SOLUTION: A heat insulating layer 3 is formed by winding a tubular or planar cold resistant material with a constitution that a cavity part is formed inside and the inside of the cavity part is vacuum or sealed with dry air. The heat insulating layer 3 is provided between an inner vessel 1 to store the liquefied gas and an outer vessel 2 to be exposed to the outside air in the liquefied gas container. Materials such as polyester elastomers, polyamide elastomers, and silicone rubber or a material which is formed by mixing carbon particles to the above materials can be used for the cold resistant material. By this constitution, the vacuum parts or the dry air in multiple layers have thermal insulation action and also the cold resistant material becomes a shock absorbing material. As a result, the liquefied gas container can withstand the shocks and the vibrations. COPYRIGHT: (C)2004,JPO
