The present invention improves an absorption characteristic of low-cycle vibrations resulting from rolling. A seat support member (20) supporting a seat is provided via a rolling absorption mechanism (30) for absorbing rolling on brackets (13) to (16) as a vehicle body side attachment member attached to the vehicle body side. Thus, rolling (low-cycle vibrations) generated by a phase shift or the like of a hydraulic suspension of the vehicle can be absorbed by the rolling absorption mechanism (30), a lateral displacement of the body of the seated person can be prevented, stability of a seated posture can be increased, and moreover occurrence of motion sickness can be suppressed. |
