Battery housing structures and battery apparatuses including the same are provided. A battery housing structure may include a case including an accommodation region in which a battery unit is accommodated, and an elastic member assembly provided in the case and configured to apply a pressure to the battery unit accommodated in the accommodation region. The elastic member assembly may include at least one first elastic member having an elastic coefficient that increases when a displacement increases and at least one second elastic member having an elastic coefficient that decreases when a displacement increases. The at least one first elastic member and the at least one second elastic member may have different structures or may be arranged in different directions.

Battery housing structure including plurality of elastic members, and battery apparatus including the same
