The main housing H may include the main boundary portion M surrounding each of the different accommodation spaces G and an opening surrounded by the main boundary portion M. For example, the opening may be formed for each accommodation space G. The opening may be formed at the bottom of the accommodation space G corresponding to the lower surface of the cell assembly B, and the main boundary portion M may be formed to surround the opening formed in each accommodation space G. Here, the lower surface of the cell assembly B may mainly face the opening and may also face a portion of the main boundary portion M surrounding the opening.
The opening of the main housing H may be closed by the first plate P1. For example, the first plate P1 may include a plurality of first plates P1 arranged in the first through fourth accommodation spaces G1 through G4, respectively. That is, the opening formed in each of the first through fourth accommodation spaces G1 through G4 may be closed by each of the plurality of first plates P1 separately formed for each of the first through fourth accommodation spaces G1 through G4. Also, while each of the plurality of first plates P1 may form the bottom of the accommodation space G, the first plate P1 may provide a supporting base of the cell assembly B accommodated in each of the first through fourth accommodation spaces G1 through G4. The first plate P1 may be coupled with the main boundary portion M surrounding the opening and may form the first coupling line L1 to close the opening.
