できる大きさとする必要がある。Assuming that all batteries are manufactured with extremely high precision and exactly the same size, a battery case can be manufactured with high dimensional accuracy and the batteries can be set in the correct position. However, for example, in an AA cylindrical battery, an outside diameter error of 1 mm is allowed. For this reason, the battery case for accommodating the cylindrical battery needs to have a size capable of accommodating the thickest cylindrical battery so that the battery case can be accommodated from thin to thick.

って、強度が低下してしまう欠点がある。The battery case shown in this figure supports a cylindrical battery at a predetermined position with positioning ribs and partition walls. However, it is necessary to design the positioning rib and the partition so that the battery case having this structure can also accommodate the thickest cylindrical battery. For this reason, when a thin cylindrical battery is stored, play can occur between the positioning ribs and partition walls and the cylindrical battery,
There is a problem that the cylindrical battery rattles in the case. In order to solve this drawback, when the thickest cylindrical battery is stored, the battery case can be slightly elastically deformed. This battery case can reduce play when a thin cylindrical battery is stored. However, in order to elastically deform the battery case, it is necessary to form the battery case thin, and there is a disadvantage that the strength is reduced.
