PROBLEM TO BE SOLVED: To provide a vibration damping structure for an automobile capable of improving a vibration damping property.SOLUTION: A vibration damping structure 1 for an automobile comprises a vibration damping layer 10 disposed between an automobile body panel 810 and an interior material 820 for damping the vibration of the automobile body panel 810, and an adhesion layer 70 bonding the vibration damping layer 10 to the automobile body panel 810 by an adhesive 71. The adhesive 71 has the 100% modulus at 20°C of 0.6 MPa or less. The average density of the vibration damping layer 10 may be 6 kg/mto 900 kg/m, and Young's modulus of the vibration damping layer 10 may be 3 N/mmor more.SELECTED DRAWING: Figure 1

    【課題】制振性を向上させることが可能な自動車用制振構造を提供する。【解決手段】自動車用制振構造1は、車体パネル810の制振のため該車体パネル810と内装材820との間に配置される制振層10と、該制振層10と車体パネル810とを接着剤71で接着した接着層70と、を備え、接着剤71の20℃における100%モジュラスが0.6MPa以下である。制振層10の平均密度は、6kg/m3以上900kg/m3以下でもよい。制振層10のヤング率は、3N/mm2以上でもよい。【選択図】図1
