Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a railway vehicle having a lightweight and low-noise floor structure. SOLUTION: In a vehicle body, an upper floor 61 is placed on an underframe 51 of a lower floor in the width direction of the vehicle through continuous joists 71. The disposition position of the joists 71 in the longitudinal direction of the vehicle corresponds to a body bolster or a cross beam which are highly rigid and hard to vibrate, and the joists are disposed on them. The vibration propagated to the upper floor 61 from the lower floor through the joists 71 is reduced by providing the joists 71 to support the upper floor 61 in a part having small vibration of the lower floor, and a solid borne sound generating in the vehicle can be reduced.
