から放出され、車外騒音を高める問題があった。Among the above-mentioned prior arts, in which the hood is composed of an elastic body having a hollow cross section, the inside of the hollow hood is pressure-controlled to improve the vibration or the running performance of the vehicle. It was supposed to work, and to change the shape of the hood in response to the movement of the vehicle on curved lines. The diaphragm shock absorber is an integrally molded product that surrounds only the through passage made of an elastic material, but is limited to the through passage structure in the inter-vehicle space. Furthermore, regarding noise, it is common to prevent rolling noise, such as rolling noise of a trolley, from penetrating inside the vehicle through the hood, and the two-piece outer hood installed in high-speed vehicles is not deformed by wind pressure. The hood, which is easy to wake up and once deformed, is apt to be subjected to wind pressure and further deforms, resulting in the generation of high aerodynamic noise. In addition, there are few cases where the entire circumference including the roof of the vehicle interior is covered with a hood. Moreover, in some experimental examples of the roof and the all-around hood surrounded by the sides, noise from the underfloor carriage is butt-jointed between the two-piece outer hoods on the side and the roof because there is no sound absorbing device on the inner surface. There is a problem that the noise is emitted from the gap generated in the part to increase the noise outside the vehicle.

The part is cut out. In order to reduce noise, the sound absorbing area is expanded by a plurality of vertical holes opened under the floor, and the vertical hole member is made of a foam material having high sound absorbing power. The outer surface of the outer surface is made of an elastic material to be a smooth surface, which is molded integrally with the foamable material or is a divided one that is inserted between the vehicles in a compressed state to connect them. The connecting device is displaced even during the expansion displacement that occurs during driving,
Alternatively, it is assumed that the movement between vehicles is followed without the division plane opening.

Since it is inserted, there is no curling or denting phenomenon due to wind pressure, and there is no generation of aerodynamic noise due to deformation from this connection part. Further, since noise from under the floor is absorbed by a plurality of vertical holes opened under the floor, no noise is generated from the inter-vehicle area. Further, since the elevating step arranged near the vehicle end side outer plate is incorporated in a smooth state with the running side outer plate, noise is not generated from this portion.
