<p>A plurality of viscoelastic layers in the form of rubber films are sandwiched between two constraint plates in the form of iron plates via polyamide-adhesive films to form an alternatingly laminated structure. Materials of the respective elements are selected so that their degrees of elasticity satisfy the relationship: constraint plate > adhesive layer > viscoelastic layer. The thickness of each rubber film is limited below a predetermined value to maintain its thermal and pressure resistance, and the rubber films are laminated up to a total thickness required for obtain a desired vibration damping property. The vibration damper, thus obtained, is excellent in vibration property, thermal and pressure resistance, and resistance against oils and solvents, and effective even under a severe environment.</p> |
