PROBLEM TO BE SOLVED: To prevent a lower end of a shelf from coming in contact with a floor surface inside a box upon storing the shelf even when the height of a locking part for hanging and holding the shelf is low.
SOLUTION: One shelf 9 is configured by connecting a front shelf 9a to a rear shelf 9b by a hinge 10. The rear shelf 9b is provided with a shaft body 13, and hooks 12 are provided on both lateral sides of the front shelf 9a and on both lateral sides of the rear shelf 9b further in front than the shaft body 13. The shaft body 13 is rotatably provided around the axis on a bearing fitting 23 provided on a side wall inside the box, and when storing the shelf 9, the shaft body 13 is hung at the back side of the box. On the other hand, during use of the shelf 9, each hook 12 is locked to a shelf receiving fitting 21 to keep the shelf 9 horizontal. The distance from the floor surface inside the box to the lower end of the shelf 9 can be secured further when the shaft body 13 is hung as the distance from a rear end of the rear shelf 9b to the shaft body 13 is made longer.
