<p><P>PROBLEM TO BE SOLVED: To expand an expansion object in a lightweight and simple structure with a big expansion torque. <P>SOLUTION: The expansion object includes: a first low rigid member 5 provided ranging over a first expansion object and second expansion objects 1 and 2 which are combined by a connecting member 3; and a holding member 10 which holds a first intermediate part of the first low rigid member 5, and connected to the connecting member 3. One end side of the first low rigid member 5 is fixed to the first expansion object 1, and the other end side of the first low rigid member 5 is fixed to the second expansion object 2. When the first and second expansion objects 1 and 2 are contained, strain energy of the first low rigid member 5 is accumulated, and when the first and second expansion objects 1 and 2 are expanded, the first and second expansion objects 1 and 2 are expanded by releasing the strain energy of the first low rigid member 5. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
