Abstract
A battery pack includes a single cell having a cylindrical shape, the single cell having a positive electrode at one end of the single cell and a negative electrode at the other end of the single cell, a plurality of the single cells being arranged in a radial direction of the single cell; a fuse; a first bus bar connected via the fuse to one electrode, from among the positive electrode and the negative electrode; a second bus bar directly connected to the other electrode, from among the positive electrode and the negative electrode; and a retaining member configured to retain the plurality of single cells from the radial direction of the single cell, in a manner such that when the fuse is disconnected, retaining force with which the single cell is retained by the retaining member decreases and the single cell moves in a direction away from the fuse.
