摘要： 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.

摘要： PROBLEM TO BE SOLVED: To provide a lightweight, low noise floor structure as to the constitution of a floor in a railway vehicle.
SOLUTION: In a vehicle body, a lower floor 1 as a reinforcement member is structurally supported by a horizontal beam 2. The lower floor 1 is fixed through a joist 3 to an upper floor 4. The joist 3 is installed along the length of the vehicle body. The joist 3 has cuts 3a along the length to vibration-insulate the lower floor 1 and the upper floor 4 from each other. As for the range of the cut 3a, its length is short to be between adjoining horizontal beams 2 and 2, or long to be over a plurality of horizontal beams 2 and 2. Vibration is thus insulated by the joist 3 provided between the floors to devices mounted on the vehicle, thereby solid born sound can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a heat and sound insulating device which is excellently adiathermanous and has improved sound insulating properties while the device is made lightweight and thin.
SOLUTION: A sound wave reflecting material 2 is formed in a flat bag shape sealed with flexible metal foil. Gas differing in sound impedance from air is charged in the sound wave reflecting material 2. A sound wave (noise) is reflected by the sound wave reflecting material 2 by variation in sound impedance. The sound wave reflecting material 2 is arranged adjacently to a heat insulator 3 which insulates heat.
