摘要

PROBLEM TO BE SOLVED: To facilitate ingress/egress of occupants by lifting and lowering the seat of a vehicle with an elevation device. SOLUTION: An arm 40 is provided on a floor panel 3 of a cab-over-engine vehicle 1 via a bracket 42, and a seat 60 is hung via a sheet plate 50. A bracket 20 attached to a rear mount rail 2 slidably supports a spiral rod 24. The spiral rod 24 is linked to the arm 40 via a link rod 26. When a motor 30 is driven, the arm 40 is swiveled between the cabin floor and a position near the round G. Inside the arm 40, a synchronization mechanism having a sprocket and a chain is mounted to maintain the seat 60 in the vertical attitude.
