<p>PURPOSE:For increasing multi-directional vibration damping effect, to provide stoppers on a circumferential line on the outer surface of an inner tank and stopper restraining bodies on the inner surface of an outer tank. CONSTITUTION:A restraining mechanism is made of a plurality of stoppers 7 protruded uniformly in the radial direction thereof on at least one circumferential line on the outer surface of an inner tank 2 and a plurality of stopper restraining bodies each uniformly faced with, at a fixed distance from, said stoppers 7 on at least one circumferential line on the inner surface of said outer tank. Thereby, the generation of inertia force that is made due to the own weight of said inner tank when the vibration of said outer tank is generated due to earthquake for example, particularly when tank is in operation, can be prevented by said stoppers and stopper restraining bodies.</p> |
