To provide a vibration control structure of a plate-like member capable of using a vibration suppression effect of a mass damper to appropriately suppress resonance with respect to a plate-like member, such as a heat insulator, for example, attached to an engine, thereby reducing vibration.SOLUTION: In a vibration-proof structure of a plate-like member that suppresses vibration of a plate-like member 4 that has a vibration source or is attached to a boss part 2 formed in a structure 1 in which vibration propagates from the vibration source, the plate-like member 4 is attached to the boss part 2 at an attachment position 6 depending on the boss part 2 via an elastic member 3 having a higher elasticity than the structure 1, and a mass part 5 having a predetermined weight is provided on an outer edge 8 close to an attachment position 6 of the plate-like member 4.SELECTED DRAWING: Figure 1 【課題】例えばエンジンに取り付けられるヒートインシュレータのような板状部材に対して、マスダンパの振動抑制効果を利用して、適切に、共振を抑制し、振動を低減することが可能な板状部材の防振構造を提供する。【解決手段】振動発生源を有するまたは振動発生源から振動が伝播する構造体１に形成されたボス部２に取り付けられる板状部材４の振動を抑制する板状部材の防振構造において、板状部材４は、ボス部２に対応する取り付け位置６で、構造体１よりも弾性が高い弾性部材３を介して、ボス部２に取り付けられており、板状部材４の取り付け位置６に近接する外縁８に、所定の重量を有するマス部５を設ける。【選択図】図１
