PURPOSE:To easily perform the mounting operation of a lid body by a method wherein a part, to be coupled and stopped, which is coupled and stopped to a coupling and stop part and a part, to be coupled, which is coupled to a coupling part are formed at the lid body and the coupling and stop part or the coupling part is made elastic. CONSTITUTION:When a lid body 2 is mounted on a box body 1, parts 23, to be coupled and stopped, at the lid body 2 are first coupled and stopped to coupling and stop parts 17 which have been formed at inserted pieces 15a on one side of the box body 1. Then, parts 24, to be coupled, at the lid body 2 are moved down, a hung-down piece 21 at the lid body is brought into contact with lid-body fitting-into prevention parts 19b, and the parts 24 to be coupled are coupled to coupling parts 18 while inserted pieces 15b on the other side are being bent. In this manner, the lid body 2 is mounted on the box body 1. Thereby, the lid body 2 can be held elastically by one side and the other side of peripheral walls 13, and the mounting operation of the lid body 2 can be performed easily without using any mounting screw. |
