PRESSURE CONTAINER COUPLING STRUCTURE

PROBLEM TO BE SOLVED: To provide pressure container coupling structure capable of strongly coupling a support structure and a pressure container to each other and capable of preventing breakdown and a coupling failure even if the internal pressure of the pressure container changes and shrinkage and deformation occur. SOLUTION: This pressure container coupling structure for coupling a pressure container 10 to be shrunken and deformed by a change of the internal pressure to support structures 20 and 30 supporting the pressure container 10 has a load support member 50 for coupling the pressure container 10 to the support structures 20 and 30 and for supporting a load to be applied to the pressure container 10 and the support structures 20 and 30, and has an extension and shrinkage absorbing member 40 for absorbing extension and shrinkage of the load support member 50 extended or shrunken by shrinkage and deformation of the pressure container 10. The load support member 50 and the extension and shrinkage absorbing member 40 are arranged between the pressure container 10 and the support structures 20 and 30 so as to be overlapped with each other in at least one part thereof.
