て組み立てできる。2. Description of the Related Art A battery pack in a case in which a first case and a second case are connected by an elastic locking arm can be easily and efficiently assembled. This is because, after opening the opening of the first case to store the battery, the second case is connected to the first case, and the opening of the first case can be closed by the second case to assemble. In the case having this structure, an elastic locking arm projecting toward the second case is provided integrally with the first case. The second case has a concave portion on the inner surface of the peripheral wall as a locking portion for hooking the locking hook of the elastic locking arm. The case with this structure can be assembled by guiding the locking hook of the elastic locking arm connected to the first case to the locking portion of the second case and connecting the first case and the second case.

る。In the above-mentioned claw structure, if the elastic locking arm is easily released, the first case and the second case cannot be firmly connected. However, in recent years, many battery packs have a tendency to form a thin case due to a demand for space saving and thinning. A thin case is easily warped, and the strength of the connecting portion is also reduced, so that it is difficult to connect with a nail structure so that it is hard to come off. This problem can be solved by forming the elastic locking arm and the connecting portion thick. However, in order to realize this, it is necessary to enlarge the outer shape of the case, and it is required to secure enough space inside the case to provide the elastic locking arm. There is a disadvantage that it becomes heavy.

Can connect cases. That is, the first case and the second case are connected to the locking hook of the elastic locking arm and the locking portion of the second case, and to the laterally projecting portion of the elastic locking arm and the second case.
The case is connected by a double connection structure by connection with the overlapping rib of the case. Therefore, in the battery pack of the present invention, by this unique connection structure, the elastic locking arm and the connecting portion are not thickly formed, and a sufficient space is provided inside the case for providing the elastic locking arm. Without using the limited space effectively, the first case and the second case can be securely connected so as not to come off.
