PROBLEM TO BE SOLVED: To provide impact-resistant structure constituted not to transmit impact acceleration to internal structure, regardless of the deformation quantity of a buffer element and the frequency characteristic of impact load when external structure having the internal structure receives the impact load from the outside. SOLUTION: A gap 5 and an elastoplastic spring 3 connected in series are provided between the external structure 1 and the internal structure 2, and a hydraulic damper 4 is provided in parallel with the gap 5.
