To provide a floor panel structure which can effectively suppress vibration of a floor panel.SOLUTION: In each of areas A1 to A12 which are surrounded by respective vehicle body skeleton members in a floor panel, plural step parts 8 having a ridge line along a shorter direction thereof are provided over a longer direction of the areas A1 to A12. A damping material 9 is coated along an outer marginal part along the longer direction of each area and an outer marginal part along the shorter direction respectively. Thus, even if the damping material 9 is not coated onto a surface of a midship part of each area A1 to A12, vibration can be sufficiently suppressed as a whole of a floor panel 1, and vibration of the floor panel 1 can be sufficiently suppressed while reducing a quantity of the damping material 9.SELECTED DRAWING: Figure 9
【課題】フロアパネルに生じる振動を効果的に抑制することができるフロアパネルの構造を提供する。【解決手段】フロアパネルにおいて各車体骨格部材で囲まれた領域A1〜A12それぞれに、その短手方向に沿う稜線を有する複数の段部8を前記領域A1〜A12の長手方向に亘って設ける。前記各領域の長手方向に沿う外縁部および短手方向に沿う外縁部それぞれに沿って制振材9を塗布する。これにより、各領域A1〜A12の中央部の表面に制振材9を塗布しなくてもフロアパネル1全体としては十分に振動を抑制することができ、制振材9の量を少なくしながらも、フロアパネル1の振動を十分に抑制することができる。【選択図】図9
