Cargo shelves 10 (objects) are arranged on the ceiling of the aircraft so as to face each other across the aisle, and a plurality of cargo shelves 10 are provided along the longitudinal direction L of the fuselage. Here, in FIGS. 1 and 2, the left side of the figure is referred to as the “front side” and the right side is referred to as the “rear side”. For example, in the case of an aircraft having one aisle, luggage racks 10 are arranged at both ends in the width direction of the fuselage across the one aisle, and the aisle side, that is, the inside of the aircraft is the "front side". And the outside of the aircraft is the "rear side".

Each luggage rack 10 includes a bottom plate 11, a side plate 12, a back plate 13, a top plate 14, and a front door 15. The bottom plate 11, the side plate 12, the back plate 13, the top plate 14, and the front door 15 have a honeycomb sandwich structure made of synthetic resin or the like in order to reduce the weight and maintain the strength. The bottom plate 11, the side plate 12, the back plate 13, and the top plate 14 form a box shape having an opening on the front surface, and the front door 15 is provided so that the opening can be opened and closed. In an aircraft, the front door 15 faces the aisle side, and the audience seats are arranged below the bottom plate 11.

An inclined surface 16 is formed on the front side of the bottom plate 11 over the entire width of the bottom plate 11 (width in the longitudinal direction L). The tip side of the inclined surface 16 is inclined obliquely upward, and here, the inclined surface 16 is a concave curved surface. The inclined surface 16 may be a flat surface or a convex curved surface as long as the space S described later can be formed. An assist grip 20A is also attached to the lower part of the luggage rack 10, specifically, to the tip of the inclined surface 16 on the front side of the bottom plate 11 over the entire width of the bottom plate 11.
