To provide an underfloor blocking plate for a railroad vehicle which can be simply removed at maintenance and inspection of equipment while preventing unprepared falling when the vehicle runs.SOLUTION: A railroad vehicle underfloor blocking plate 10 detachably blocks an opening 12 formed in an underfloor bottom face 11 of a railroad vehicle 1. The opening comprises a support shaft part 3 extending horizontally along an end edge 121 of the opening and a stop part 4 formed along the other edge 122. The underfloor blocking plate comprises: a blocking plate body 2 formed like a flat plate; a locking part 5 which is fixed to the blocking plate body, allows the blocking plate body rotate only a prescribed angle α in an upward direction X from a supporting position that is undetachably supported by the support shaft part, and also is formed detachably only at a detachable position shifted a prescribed length d1 in the shaft axis direction Y; and a stopping part 6 fixed to the blocking plate body and formed to be coupled with the stopping part at an another supporting position.SELECTED DRAWING: Figure 2

    【課題】機器等を保守点検するときには簡単に取り外しできると共に、車両走行時における不用意な脱落を防止できる鉄道車両の床下塞ぎ板を提供すること。【解決手段】鉄道車両1の床下底面11に形成される開口部12を着脱可能に閉塞する鉄道車両の床下塞ぎ板10である。開口部には、その一端縁121に沿って水平方向に延設された支持軸部3と、その他端縁122に形成された止め部4とを備えている。また、床下塞ぎ板には、平板状に形成された塞ぎ板本体2と、塞ぎ板本体に固定され支持軸部に対して係脱不能に支持される支持位置より塞ぎ板本体を上方向Xへ所定角度αだけ回動させ、かつ軸方向Yへ所定長d1だけ移動させた着脱位置のみで係脱可能に形成された被係止部5と、塞ぎ板本体に固定され支持位置で止め部に連結されるように形成された被止め部6とを備えた。【選択図】 図2
