Claims

[Scope of utility model registration request]

A battery pack consisting of a plurality of batteries arranged side by side with their anodes and cathodes positioned in the same direction, and each battery's outer periphery covered with an insulating case, is a part of the main body of an electrical device, etc. In a battery storage case that can be loaded into a battery pack storage part provided with an opening, approximately the center in the width direction of one of the flat surfaces formed on each of the upper and lower sides of the battery pack. In addition, a concave portion is formed in the opening formed at one end of the battery pack, extending from the mouth portion to the middle portion of the battery pack, and an incorrect loading prevention portion is formed from the middle portion to the other end of the battery pack. , the inner circumferential surface of the battery pack housing has a length that is approximately the same as the entire length of the groove from the position of the anode terminal and the cathode terminal located on the opposite side of the opening of the housing. 5. A device for preventing reverse loading of a battery, characterized in that it comprises a projecting protrusion having a shape that matches the concave strip.
