However, as is clear, since the side wall 19E on the base side is inward from the base end surface of the case body by, for example, about 5 mm, the width of the storage case is widened accordingly, resulting in a large mold and cost. There are problems such as a large burden and a large bulk as a whole, which makes the packaging bulky and the burden of transportation becomes large. For example, the cost of the mold varies depending on the area, and the cost of the mold is allocated to the cost of the product and bears it. Therefore, it is desirable that the cost of the mold is low. In addition, the fact that it is bulky requires more storage space and exhibition space, and the fact that it is bulky means that there is less loading on a truck of the same area, which is reflected in the unit price of the product. However, eliminating the side wall 19E on the base end side of the case body has a problem in terms of strength.
