PURPOSE: An elastic structure with a variable forming piston made of a flexible sealing membrane is provided to highly improve the degree of freedom of design and the performance of a designed product in technical fields such as vehicles, vessels, and aircrafts etc. by using a pressure container having various forms with the superior degree of freedom and large size as the role of a cylinder. CONSTITUTION: An elastic structure with a variable forming piston made of a flexible sealing membrane comprises a pressure container and a variable forming piston. The pressure container comprises an opening at one end and performs the role of a cylinder. The variable forming piston is made of at least one flexible sealing membrane and is connected to the close position of the opening. A first pressure space formed by the variable forming piston and the pressure container is set up as a different pressure with the nth pressure space of outside. The sealing membrane moves the variable forming piston by separating in the state of being adhered to the inside of the pressure container when being pulled in the outside direction of the pressure container as a tensile direction. |
