PROBLEM TO BE SOLVED: To provide an underfloor arrangement appliance for a railway vehicle comprising: a housing 2 disposed on an underfloor of a railway vehicle; a component stored in the housing 2; and a lid body 4 detachably attached to an opening 21 which is opened on a bottom face of the housing 2, in which plural tongue piece parts 43 projecting toward outsides of one set of opposite sides of the lid body 4 are provided on the lid body 4, and plural reception piece parts 23 that are disposed below the tongue piece parts 43 when the lid body 4 is attached to the opening 21, and with which the tongue piece parts 43 contact when the lid body 4 is fallen, are provided on the bottom face of the housing 2, thereby, falling of the lid body 4 from the housing 2 can be surely prevented.SOLUTION: Respective tongue piece parts 43 are formed into a groove-shape in which side edge parts 43b in a direction orthogonal to an opposite direction of the opposite sides, are bent downward, and directed downward, and respective reception piece parts 23 are formed into a groove-shape in which side edge parts 23b in a direction orthogonal to the opposite direction of the opposite sides, are bent upward and directed upward.SELECTED DRAWING: Figure 2
【課題】鉄道車両の床下に設けられる筐体2と、この筐体2内に収容される部品と、筐体2の底面に開設された開口21に着脱自在に装着される蓋体4とを備える鉄道車両用床下配置機器であって、蓋体4に、蓋体4の一組の対辺の外方に張り出す複数の舌片部43が設けられると共に、筐体2の底面に、蓋体4が開口21に装着された状態で舌片部43の下方に位置して、蓋体4が落下したとき舌片部43が当接する複数の受片部23が設けられるものにおいて、蓋体4が筐体2から脱落することを確実に防止できるようにする。【解決手段】各舌片部43は、前記対辺の対向方向と直交する方向両側の側縁部43bが下方に屈曲した下向きの溝形に形成され、各受片部23は、前記対辺の対向方向と直交する方向両側の側縁部23bが上方に屈曲した上向きの溝形に形成される。【選択図】図2
