VIBRATION ISOLATING FLOATING FLOOR STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a vibration isolating floating floor structure of a vehicle body capable of improving riding comfort and reducing in-vehicle noise. SOLUTION: A seat floor plate 24 wherein a seat 16 is mounted is supported by a bush type vibration isolating device 26 and a hybrid type vibration isolating device 28 so as to float from a beam. In the seat floor plate 24, both side parts in a vehicular width direction (an arrow W direction) is supported by the bush type vibration isolating device 26 setting stiffness in horizontal direction to be high, and a center part in the vehicular width direction is supported by the hybrid type vibration isolating device 28 having high vertical damping force. Though vibrations from the beam intend to transfer to the seat floor plate 24, the bush type vibration isolating device and the hybrid type vibration isolating device 28 are interposed between the beam and the seat floor plate 24 to prevent the transmission of vibrations to the floor plate side, so that the seat floor plate 24 is hard to be vibrated.
