Abstract:
1. A battery pack, comprising: a cell having a surface including a coupling groove; a circuit board electrically connected to the cell; a coupling member, the coupling member having one end coupled to the circuit board, the coupling member having another end contacting the surface of the cell and having a coupling hole therein, the coupling hole corresponding to the coupling groove; a cover surrounding the circuit board, the cover contacting the surface of the cell adjacent to the coupling groove, the cover having a mounting groove and a through-hole corresponding to the coupling groove, the mounting groove surrounding the through-hole; a screw coupled to the coupling groove through the coupling hole and the through-hole, the screw having a head part and a body part extending from the head part, an underside of the head part contacting a bottom surface of the mounting groove; and an elastic supporting member contacting the underside of the head part of the screw and an upper side of the coupling member, at least a part of the elastic supporting member being inside the through-hole, the elastic supporting member being in a compressed state and exerting a restoring force against the upper side of the coupling member to bias the coupling member against the surface of the cell.
