<p><P>PROBLEM TO BE SOLVED: To provide a vibration-proof floating floor structure with improved riding comfort suitable to a high-speed moving body such as rolling stock for high speed traveling. <P>SOLUTION: A floor plate 24 for seats having seats 16 on it are supported by a vibration-proof device 26 to float from a beam. Vibration from the beam is transmitted to the floor plate 24 for seats, while a metal spring 46 of the vibration-proof device 26 is provided between the beam and the floor plate 24 for seats to prohibit transmission of vibration to the floor plate, so that the floor plate 24 for seats is less likely vibrated. As the floor plate 24 for seats is vibrated, a shaft member 32 and an outer cylinder 30 in the vibration-proof device 26 are relatively displaced in the axial direction, and a slide member 42 slides to an outer circumferential surface of the shaft member 32 to generate damping force. In addition, air in a main fluid chamber 44 formed inside the shaft member 32 and the outer cylinder 30 passes through a gap between the slide member 42 and the shaft member 32 to generate damping force, thus effectively damping vibration of the floor plate 24 for seats, and improving ride comfort. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
