A seat unit includes a seat cushion, a tray compartment located under the seat cushion, a tray which is made storable in the tray compartment, a seat cushion swing mechanism which makes it possible to expose the top side of the tray compartment by swinging up the seat cushion about a support shaft provided at one end of the seat cushion, and a tray support provided on a seat-side member for supporting the tray in such a manner that the tray can be moved between a storage position inside the tray compartment and a service position on one side of the seat cushion after swinging up the seat cushion.
