BATTERY PACK

To provide a battery pack that can prevent incorrect assembly of storage batteries due to incorrect orientation of the storage batteries or incorrect connection points of connection cables.SOLUTION: In a battery pack 1, the plurality of storage batteries 10 have a plurality of positive electrode terminals 11A, 11B, a plurality of negative electrode terminals 21A, 21B equal in number to the positive electrode terminals 11A, 11B, and a pair of protrusions 31A, 31B protruding between the positive electrode terminals 11A, 11B and the negative electrode terminals 21A, 21B in the direction of the height of the positive electrode terminals 11A, 11B and the negative electrode terminals 21A, 21B and extending in the direction of partition between the positive electrode terminals 11A, 11B and the negative electrode terminals 21A, 21B, and a fixture 5 for positioning the plurality of storage batteries 10 is fitted between the pair of protrusions 31A, 31B. The thickness of one of the pair of protrusions 31A and 31B is different from that of the other.SELECTED DRAWING: Figure 1 【課題】蓄電池の向きの誤りや接続ケーブルの接続先の誤りにより蓄電池を誤組付けしてしまうことを防止できる組電池を提供すること。【解決手段】組電池１において、複数の蓄電池１０は、複数の正極端子１１Ａ、１１Ｂと、正極端子１１Ａ、１１Ｂと同数の複数の負極端子２１Ａ、２１Ｂと、正極端子１１Ａ、１１Ｂと負極端子２１Ａ、２１Ｂとの間で正極端子１１Ａ、１１Ｂおよび負極端子２１Ａ、２１Ｂの高さ方向に突出し、正極端子１１Ａ、１１Ｂと負極端子２１Ａ、２１Ｂとを仕切る方向に延伸する一対の突出部３１Ａ、３１Ｂと、を有し、一対の突出部３１Ａ、３１Ｂの間に、複数の蓄電池１０を位置決めする固定具５が嵌め込まれている。一対の突出部３１Ａ、３１Ｂの一方と他方とで厚みが異なっている。【選択図】図１
