PROBLEM TO BE SOLVED: To provide a luggage door structure enabling reduction in resonance frequency.SOLUTION: Rubber bushes 18B, 18C newly lie between a luggage door hinge 14 and a luggage door, and thereby in a luggage door structure 10 comprising the luggage door, the luggage door hinge 14 and the like, vibration is transmitted to the luggage door from the side of a vehicle body via the luggage door hinge 14 and the bushes 18B, 18C. Namely, a spring constant of the luggage door structure is reduced by adding one of series elements transmitting the vibration, and the resonance frequency of the luggage door structure is reduced. Also, because only the rubber bushes 18B, 18C are added, the change in vehicle weight is minor, the capacity of a luggage chamber is not varied, and moreover standardized luggage door hinge 14 can be applied.SELECTED DRAWING: Figure 2

    【課題】共振周波数を低減できるラゲージドア構造を提供する。【解決手段】ラゲージドアヒンジ14とラゲージドアとの間に新たにゴム製のブッシュ18B、18Cを介在させたため、ラゲージドアとラゲージドアヒンジ14等からなるラゲージドア構造10において、車体側からラゲージドアヒンジ14、ブッシュ18B、18Cを介してラゲージドアに振動が伝達される。すなわち、振動を伝達する直列要素を一つ追加したことによって、ラゲージドア構造のバネ定数が低下し、ラゲージドア構造の共振周波数が低減される。また、追加されるのが、ゴム製のブッシュ18B、18Cのみなので、車両重量の変化も軽微であり、荷室の容量も変化せず、さらに、標準化されたラゲージドアヒンジ14を適用することができる。【選択図】図2
