MOUNTING STRUCTURE OF INTERIOR MEMBER OF RAILWAY VEHICLE

To provide a mounting structure of an interior member of a railway vehicle by which the interior member can be mounted on a vehicle body structure without requiring drilling work which causes generation of chips.SOLUTION: A vehicle structure body 11 covers a boundary between an interior panel 14 and a floor mat 13 with a baseboard 20 and includes an inner skeleton member 19 supporting at least the interior panel 14 from the side of a rear surface 142 of the interior panel 14. The inner skeleton member 19 includes a joint part 193 joined with the interior panel 14 on the side of the rear surface 142. The interior panel 14 includes a fixing member 16 and a floating nut 18 at an end part on the side of the floor mat 13, of the rear surface 142. The fixing member 16 can be moved between a separation position where a gap G11 is generated into which the joint part 193 can be inserted from a direction parallel to a surface 141 between the fixing member 16 and the rear surface 142 by being separated from the rear surface 142 and a proximity position where the fixing member 16 and the rear surface 142 hold the joint part 193 inserted in the gap G11 to be joined with each other.SELECTED DRAWING: Figure 3 【課題】切り粉の発生原因である穴あけ作業を要することなく内装部材を車両構体に取り付け可能な、鉄道車両の内装部材の取付構造を提供すること。【解決手段】車両構体１１は、内装パネル１４と床敷物１３の境目を巾木２０で覆い隠しており、少なくとも内装パネル１４を、内装パネル１４の裏面１４２側から支持する内骨部材１９を備え、内骨部材１９は、裏面１４２側で内装パネル１４と結合する結合部１９３を備え、内装パネル１４は、裏面１４２の、床敷物１３の側の端部に、固定部材１６とフローティングナット１８とを備え、固定部材１６は、裏面１４２から離間することで、固定部材１６と裏面１４２との間に、表面１４１と平行な方向から結合部１９３を挿し込み可能な間隙Ｇ１１を生じさせる離隔位置と、固定部材１６と裏面１４２とが、間隙Ｇ１１に挿し込まれた結合部１９３を挟持し、結合を行うための近接位置と、の間を移動可能であること。【選択図】図３
