Abstract
The battery apparatus according to the present invention has the structure in which a lid is engaged with a battery storage to cover a storage portion storing a battery unit via a first fixing means employing a simple structure. Further, the battery storage is formed of the frame and a closing unit engaged via a second fixing means only employing a simple structure. Furthermore, since the battery storage, or the lid, or the closing unit is formed of metal; and the thickness thereof is made thinner, the capacity of the storage portion can be increased to the extent of the reduction in the thickness, whereby the amount of electricity can be increased.
