PROBLEM TO BE SOLVED: To provide a vehicle floor panel structure which enables further improvement of rigidity of a floor panel without adding reinforcing components and further reduction of noise caused by vibration during traveling etc.SOLUTION: The vehicle floor panel structure (a floor panel structure 100) according to the invention includes: a floor panel 110 forming a floor surface of a vehicle; a cross member extending over the floor panel in a vehicle width direction; a center tunnel 112 formed in a center of the floor panel when viewed in the vehicle width direction and protruding to the vehicle inner side in a vehicle fore and aft direction; a bead 114 which is formed at a portion of the floor panel, which is located at the outer side of the center tunnel when viewed in the vehicle width direction, ranges from a front end to a rear end of the floor panel so as to intersect with the cross member, and expands upward; and expansion parts 116a to 116d formed at areas of the floor panel which are partitioned by the bead and the cross member and expanding downward.SELECTED DRAWING: Figure 2

    【課題】補強用の部品を追加することなくフロアパネルの更なる剛性の向上を図ることができ、走行時等の振動に起因する騒音をより低減することが可能な車両用フロアパネル構造を提供する。【解決手段】本発明にかかる車両用フロアパネル構造(フロアパネル構造100)の構成は、車両の床面を構成するフロアパネル110と、フロアパネル上を車幅方向に延びるクロスメンバと、フロアパネルの車幅方向中央に形成されていて車両前後方向にわたって車内側へ隆起したセンタートンネル112と、フロアパネルのうちセンタートンネルよりも車幅方向外側に形成されていてクロスメンバと交差するようにフロアパネルの前端から後端までわたっている上方に膨出したビード114と、フロアパネルのうちビードおよびクロスメンバによって区画された領域に形成されていて下方に膨出している膨出部116a〜116dとを備えることを特徴とする。【選択図】図2
