To provide a vibration-proof structure capable of remarkably reducing both a reaction magnification and a displacement amplitude in a specific vibration frequency range.SOLUTION: A vibration-proof structure comprises: a structure 2; a first support spring (first spring element) 5 provided on the structure 2; a first floating floor (first vibrating body) 3 provided on the structure 2 via the first support spring 5; a second support spring (second spring element) 6 provided on the first floating floor 3; a second floating floor (second vibrating body) 4 provided on the first vibrating body via the second support spring 6; and an inertia mass device 8 which is provided in parallel with the first support spring 5 between the structure 2 and the first floating floor 3. A mass of the first floating floor 3 is set equal to or more than a mass of the second floating floor, spring rigidity of the first support spring 5 is set smaller than spring rigidity of the second support spring 6, and an inertia mass of the inertia mass device 8 is set on the basis of a specific formula.SELECTED DRAWING: Figure 1
【課題】特定の振動数領域において反力倍率と変位振幅の両方を大幅に低減できる防振構造を提供する。【解決手段】構造体２と、構造体２の上に設けられた第１支持ばね（第１ばね要素）５と、第１支持ばね５を介して構造体２の上に設けられた第１浮き床（第１振動体）３と、第１浮き床３の上に設けられた第２支持ばね（第２ばね要素）６と、第２支持ばね６を介して第１振動体の上に設けられた第２浮き床（第２振動体）４と、構造体２と第１浮き床３との間に第１支持ばね５と並列に設けられた慣性質量装置８と、を有し、第１浮き床３の質量は、第２浮き床の質量以上に設定され、第１支持ばね５のばね剛性は、第２支持ばね６のばね剛性よりも小さく設定され、慣性質量装置８の慣性質量は、特定の式に基づいて設定される。【選択図】図１
