PROBLEM TO BE SOLVED: To provide a floor structure for a railway vehicle in which a topical potent magnetic field may be hardly generated on a floor surface of a cabin while suppressing increment in weight.SOLUTION: In a floor structure 10, a power line 20 extending in a rail direction at a center part in a railroad tie direction is arranged below a cabin floor 7a and a shield plate 30 suppressing a magnetic field generated on the cabin floor 7a is arranged between a floor plate 2 and the cabin floor 7a. The shield plate 30 comprises a first shield plate 31, second shield plate 32 and third shield plate 33 constructed in a thin plate. The first shield plate 31 covers upper side of the power line 20 in an upper surface 2a of the floorboard 2. The second shield plate 32 covers: an upper surface 31a and an end surface 31b of the first shield plate 31 at one side in the railroad tie direction: and the upper surface 2a of the floorboard 2 at one side in the railroad tie direction. The third shield plate 33 covers: the upper surface 31a and an end surface 31c of the first shield plate 31 at the other side in the railroad tie direction; and the upper surface 2a of the floorboard 2 at the other side of the railroad tie direction.

    【課題】重量の増加を抑えつつ、客室床面に局所的に強い磁界を生じ難くできる鉄道車両床構造を提供すること。【解決手段】床構造10では、客室床面7aより下側に枕木方向の中央部でレール方向に延びる動力線20が配置され、床板2と客室床面7aとの間に、客室床面7aで生じる磁界を抑制するシールド板30が配置されている。このシールド板30は、薄板状に構成された第1シールド板31と第2シールド板32と第3シールド板33とを有する。第1シールド板31は、床板2の上面2aのうち動力線20より上側を覆っている。第2シールド板32は、第1シールド板31の枕木方向の一方側の上面31a及び端面31bと床板2の上面2aのうち枕木方向の一方側とを覆っている。第3シールド板33は、第1シールド板31の枕木方向の他方側の上面31a及び端面31cと床板2の上面2aのうち枕木方向の他方側とを覆っている。【選択図】 図3
