To form a light-weight floor structure having sound insulating properties and fire resistance easily.SOLUTION: A floor structure of a railway vehicle includes: a lower plate placed on an underframe; a lower heat insulation material disposed on the lower plate; a vibration control plate held on the lower plate by a supporting base; and a refractory panel disposed on the vibration control plate. An expansive refractory paint is applied to at least one of an area between the lower plate and the lower heat insulation material and an area between the lower heat insulation material and the vibration control plate.SELECTED DRAWING: Figure 1
