PROBLEM TO BE SOLVED: To effectively suppress vibrations of a rear floor panel, while suppressing the increase of weight of a vehicle.SOLUTION: In a vehicle rear floor structure S, a storing box 30 is configured as a foamed resin molding, so that the weight-reduction of the storing box 30 can be attempted. The storing box 30 abuts on a front part of a bottom wall portion 12A on a floor pan 12 at a projecting portion 44. Namely, a front part of a bottom wall portion 12A which becomes an antinode in a primary natural frequency mode of the rear floor panel 10 is received by the projecting portion 44 of the storing box 30. Therefore, the storing box 30 is acted as a dynamic damper. Consequently, a resonance frequency of the rear floor panel 10 including the storing box 30 is scattered, and a vibration level of the rear floor panel 10 can be reduced.SELECTED DRAWING: Figure 1

    【課題】車両の重量アップを抑制しつつリヤフロアパネルの振動を効果的に抑制する。【解決手段】車両リヤフロア構造Sでは、収納ボックス30が、発泡樹脂成形体として構成されているため、収納ボックス30の軽量化を図ることができる。また、収納ボックス30は、突出部44においてフロアパン12における底壁部12Aの前部に当接されている。すなわち、リヤフロアパネル10の1次の固有振動モードにおいて腹となる底壁部12Aの前部を収納ボックス30の突出部44で受けるようになる。このため、収納ボックス30をダイナミックダンパとして作用させるように構成できる。これにより、収納ボックス30を含むリヤフロアパネル10の共振周波数が分散されて、リヤフロアパネル10の振動レベルを低減することができる。【選択図】図1
