<P>PROBLEM TO BE SOLVED: To obtain a deployment structure and a shock absorber capable of being installed in a narrow and small part, not requiring a great deal of power for deploying, and capable of deploying from a flat surface to a three-dimension state to effectively absorb impact energy. Ž<P>SOLUTION: The deployment structure 10 comprises a fixing plate 22, a deployment plate 24 arranged facing to and in parallel with the fixing plate 22, a plurality of first rotation parts 28 rotatably provided for the fixing plate 22, a plurality of second rotation parts 30 rotatably provided for the deployment plate 24, a plurality of arm members 32 connected to the first rotation parts 28 and the second rotation parts 30, and an air bag device 16 for separating the deployment plate 24 from the fixing plate 22. At the time of deploying, the deployment plate 24 is separated from the fixing plate 22 by the air bag device 16, the arm members 32 rotate, and the deployment plate 24 slidably stands up. When impact force acts on the deployment plate 24, the impact force is transmitted to the arm members 32, and impact energy is absorbed by axial force, bending resistance, and plastic deformation of the arm members 32.
