品とはならなかった。2. Description of the Related Art Conventionally, in a general battery pack in a resin case, if the resin case is formed by fitting each of two divided resin case halves, the shape of each case is different. Therefore, it was necessary to create a mold for each of the resin case halves and use two types of parts. For example, 60-160
As in the case of Japanese Patent Application Laid-Open No. 465/465, even a pair of resin case halves having substantially the same shape are completely identical due to the presence or absence of a through-hole for attaching an external terminal and the difference in a concave and convex portion for fitting. did not become.

It is a box-shaped hollow having an opening surface symmetrical with respect to the center line, and the outer peripheral side wall portion of the opening surface is provided with a pair of fitting concave portions and fitting convex portions at positions symmetrical with respect to the center line. A notch for the terminal is provided, and the bottom portion is shifted from the center line.
Two resin case halves having the same shape, each having a battery holding rib at the position, with their respective opening surfaces facing each other so that the outer peripheral side wall portion of the opening surface fits unevenly, and one or two are formed in the formed space. A battery group consisting of a plurality of batteries, which is mechanically and electrically connected, is housed therein, and the outer peripheral side wall portion of the opening surface is integrated by concave and convex fitting.

Position. Then, the case fitting protrusion 8 of one resin case half and the fitting recess 9 of the other resin case half are fitted together, and the case fitting recess of one resin case half and the other resin case are fitted. By fitting the fitting projections of the case half, the battery pack 5 that houses the battery group using two identical parts is formed.
