PROBLEM TO BE SOLVED: To reduce removal of a cover from an outside plate.SOLUTION: A vehicle under-floor structure 10 comprising: a housing 11 which is provided at a lower part 2 of a railway vehicle 1 and of which an outside plate 12 covers underfloor equipment 34 of the railway vehicle 1; an opening 13 formed in the outside plate 12; a cover 14 which is so fitted to the outside plate 12 as to close the opening 13; a latch 23 which is provided on the cover 14, and is fitted to a latch fitting part 22 of the cover 14; and a latch receiver 25 which is provided on the outside plate 12, and is brought into contact with a latch reception contact part 24 of the latch 23 separated from the latch fitting part 22 so that the cover 14 is removed from the outside plate 12. A deformation suppression member 29 is brought into contact with a deformation suppression member contact part 28 of the latch 23 from a side opposite to the latch reception contact part 24 against a force which acts on the latch 23 from the latch receiver 25 via the latch reception contact part 24 by an external force F onto the cover 14, whereby deformation of the latch 23 is suppressed. Thus, removal of the cover 14 from the outside plate 12 can be reduced.SELECTED DRAWING: Figure 1
【課題】カバーが外板から外れることを低減する。【解決手段】鉄道車両1の下部2に設けられ、その外板12で鉄道車両1の床下機器34を覆う筐体11と、外板12に形成された開口部13と、開口部13を塞ぐように外板12に取付けられたカバー14と、カバー14に設けられ、カバー14の掛金取付部22に取り付けられた掛金23と、外板12に設けられ、カバー14が外板12から外れないように掛金取付部22から離隔した掛金23の掛金受当接部24に当接する掛金受25とを備えた車両床下構造10において、カバー14に対する外力Fによって掛金受25から掛金受当接部24を介して掛金23に作用する力に対して、変形抑制部材29が掛金受当接部24とは反対側から掛金23の変形抑制部材当接部28に当接することにより、掛金23の変形が抑制される。これにより、カバー14が外板12から外れることを低減することができる。【選択図】図1
