PROBLEM TO BE SOLVED: To keep lids opened to prevent the lids from hampering a work for putting an article stored in and out of a cubic storing space. SOLUTION: A storing box 1 is equipped with: four side faces 15 to 18 which form the cubic storing space 2; and inner lids 3 and 4 and outer lids 5 and 6, which are foldable to the sides of the upper sides 14 of the four side faces 15 to 18, respectively. The inner lid 3 is adjacent to the outer lid 5, and the inner lid 4 to the outer lid 6. The outer lids 5 and 6 have projecting pieces 7 and 10, respectively, and the inner lids 3 and 4 have recessed parts 8 and 11, respectively. When the inner lids 3 and 4 and the outer lids 5 and 6 are folded to the outside of the side faces 15 to 18 to open the storing space 2, the projecting pieces 7 and 10 engage with the recessed parts 8 and 11, respectively, to keep the inner lids 3 and 4 and the outer lids 5 and 6 in folded postures.
