もある。However, in this type of battery pack, the battery capacity is 4L.
, it is necessary to ensure the holding structure for the 4R battery storage case 1 (or battery storage case half-closed 100.100). In other words, when a battery pack is being transported or when an electronic device with a punctured battery is used, impact forces and vibrations are applied to the battery pack, so if the holding structure is not secure, the electrodes inside the unit battery may move. Otherwise, the reliability of electronic equipment may be seriously impaired due to short-circuiting where one polarity part contacts the other polarity part, or an internal short-circuit due to deformation of the electrode plate. Because it will be. There is also a risk that the battery may generate heat or catch fire.
なお、後述の本発明者等の実験結果かられかるように、
電極板の移動は、主として縦方向（素電池の長手方向）
に現れ、この方向に衝撃力や振動が発生すると、かかる
移動が顕著に現れる。Furthermore, as can be seen from the experimental results of the present inventors described below,
The movement of the electrode plate is mainly in the vertical direction (longitudinal direction of the unit cell)
When impact force or vibration occurs in this direction, such movement becomes noticeable.

In the case of a holding structure that elastically supports the upper ends of the unit cells 4L, 4R, the narrow ribs 500L, 500R or 501... are integrally extended in a so-called cantilevered state, so that the elastic support is not possible. Since the force is weak and the unit cells 4L and 4R are partially elastically supported, there is a limit to how effectively the battery can be protected against punctures from the above-mentioned impact force and vibration.
また、蓋体２０の構造が複雑になり、製作性が悪くなる
という欠点もある。Another disadvantage is that the structure of the lid body 20 becomes complicated and the manufacturing efficiency becomes poor.
