When pushed down, the lower column 28 descends somewhat in the storage box 5, the lower portion of the column 10 is inserted to a height in the middle of the storage box 5, the lids 3 and 4 are in the normal positional relationship, and the outer wall portion A slight resistance is generated when it comes into contact with the bent portion 24 of the 19, but if the upper lid 4 is continuously pushed down, the outer wall portion
At least the lower portion of the bending portion 24 is flexed outwardly from the bent portion 24, and the wall spacing of the lower space portion 48 is locked with the contact angle between the lower end of the lower strut 28 and the bent portion 24 reduced.
It extends to a size equal to the thickness of the lower column 28 of the eleventh part. Therefore, the lower support column 28 can be lowered without damaging the locking claws 11, and when the locking claws 11 projecting from the inner surface of the lower support column 28 are in a horizontal position with the inner wall lower end surface 21, Since the frictional resistance between the apex of the retaining pawl 11 and the surface of the inner wall portion 18 disappears, the outer wall portion 19 restores to its original shape, and the retaining pawl 11 is caught on the inner wall lower end surface 21 as the retaining portion.
