Abstract
A battery pack includes: a battery module formed by stacking battery cells; an upper frame positioned on an upper surface of the battery module; a first side frame positioned on a first side surface of the battery module; and a second side frame positioned on a second side surface of the battery module facing the first side frame. The upper frame includes one or more first hinge parts positioned at one end of the upper frame. The first side frame includes one or more first poles positioned at an upper edge of the first side frame and fastened to the first hinge part. A first opening into which the first pole is inserted is formed in the first hinge part, and the first opening is formed obliquely so as to face between a direction perpendicular to the upper frame and a direction parallel to the upper frame.
