The front and the back folding side walls 2, 3 can be folded at a center to be in a contained condition, and they can be developed from a folded condition to be in a usage condition. In this usage condition, mounting parts 6, 6 provided from lower parts of the folding side walls 2 to lower parts of the right and left side walls 1, 1 are developed right and left, and an observation aperture (n) is formed under the right and the left side wall 1. Mounting parts 7 provided from lower parts of the right and the left side walls 1, 1 to the back folding side wall 3 are developed backward, and an observation aperture is also formed under the back folding side wall 3. |
