At least two divided boards and a flexible net-like sheet that is attached in the vicinity of the adjacent edge on the storage unit side of the divided boards adjacent to each other when the opening is closed, and is stored in the storage when the opening is closed In the vicinity of the opening on the inner side surface of the storage portion, a fitting groove portion into which each anti-adjacent edge of the adjacent divided boards is inserted is formed. When the adjacent edge is inserted into the fitting groove portion, the both ends stand up against each other, and the net-like sheet is suspended in the vicinity of the adjacent edge of each divided board. Characterized in that it is suspended on a suspension bridge shape between over de.

  According to the present invention, the load is placed on the net-like sheet suspended like a suspension bridge between the two split boards in the standing posture, and the movement is restricted by being held at the bottom of the net-like sheet by its own weight. Therefore, even a load that is easy to roll can be transported in a stable state.

  In addition, since the net-like sheet is stored in the storage unit when not in use and the floor board covers the upper part of the net-like sheet, the net-like sheet does not appear in the rear cargo compartment, the appearance of the rear cargo compartment is good, and the net-like sheet is in the rear part. It does not interfere with the storage of other luggage in the luggage compartment.

  Furthermore, since the net-like sheet can be easily switched between the use state and the accommodation state simply by raising or lying the divided board, the net-like sheet can be changed between the use state and the accommodation state as in Patent Document 2 above. It is easier to use than attaching / detaching the net-like sheet to / from the hook each time it is switched.
