1. A battery pack comprising: a plurality of battery cells, each comprising a cell vent; frames arranged together with the plurality of battery cells in an arrangement direction and coupled together such that frames of each of pairs of adjacent frames face each other with a battery cell of the plurality of battery cells therebetween, each of the frames comprises only a partial guide rib that, together with a partial guide rib of an adjacent frame, surrounds the cell vent of the battery cell between the frames; a top cover arranged above the frames to cover the frames and comprising protruding barrier walls each surrounding a first side and a second side opposite the first side of the guide ribs of a respective pair of adjacent frames along the arrangement direction; and a wiring board between the top cover and the frames, the wiring board having through-holes through which the guide ribs of the respective pair of adjacent frames or the protruding barrier wall corresponding thereto pass, wherein leading ends of the guide ribs of the respective pair of adjacent frames in a protruding direction of the guide ribs are spaced apart, by a clearance gap along the arrangement direction, from a leading end of the protruding barrier wall corresponding thereto in a protruding direction of the protruding barrier wall such that the battery cells are allowed to move along the arrangement direction due to swelling, and wherein the wiring board is above or below the clearance gap in a stacking direction from the frames toward the top cover.
