PROBLEM TO BE SOLVED: To solve the difficulty of securing rigidity and strength against an airtight pressure by a hollow-shaped material, the hollow-shaped material avoiding interference with air conditioning ducts and underfloor equipment densely disposed on both sides of an underframe in a high-speed vehicle.SOLUTION: A rail vehicle includes: a roof structure forming a top face; a side structure forming a side face; an end structure forming an end face in a longitudinal direction; and an underframe forming a bottom face. The underframe is formed with a hollow-shaped material made of two surface plates and ribs connecting the surface plates to each other. The thickness of the hollow-shaped material forming the center portion in a width direction of the underframe is arranged thicker than the thickness of the hollow-shaped material forming the end parts in the width direction of the underframe.SELECTED DRAWING: Figure 2
【課題】高速車両の台枠では、その上下に空調用ダクトや床下機器が密集しているため、それらとの干渉を回避した中空形材によって気密圧力に対する剛性や強度を確保することは困難な状態にある。【解決手段】軌条車両は、上面を構成する屋根構体と、側面を構成する側構体と、長手方向の端面を構成する妻構体と、下面を構成する台枠とから成り、台枠を二枚の面板と該面板同士を接続するリブから成る中空形材で構成し、台枠の幅方向中央部を構成する中空形材の厚みを台枠の幅方向端部を構成する中空形材の厚みより厚くする。【選択図】図2
