PROBLEM TO BE SOLVED: To surely prevent a partitioning plate 4 from being removed from a wall body by the engagement of hook-shape engaging parts into a hooked state even if a confronted distance between the wall bodies is increased by an opening force when an excessive weight of housed small articles is applied, or small articles being too large are forcibly tried to be housed, and the partitioning plate separates from the wall body due to the increase of the distance and tries to come off. SOLUTION: This box body 1 made of a synthetic resin is equipped with an attaching/detaching mechanism 5 which can detachably arrange the partitioning plate 4 between the confronted wall bodies 3 and 3. The attaching/detaching mechanism is constituted of a pair of confronted attaching/detaching parts 6 and 7 which are respectively formed on the wall surfaces of the wall bodies, and the side end surfaces of the partitioning plate. On respective attaching/detaching parts, hook-shape engaging parts 8 and 9 which can prevent the partitioning plate from being removed from the wall bodies by engaging with each other into a hooked state when the confronted distance L between the wall bodies is increased are formed.
