PROBLEM TO BE SOLVED: To properly arrange batteries and a compensating circuit in a battery pack, to set the batteries at prescribed positions and to arrange a battery holder at the prescribed position by providing step sections on walls perpendicularly crossing the other walls of a battery pack body. SOLUTION: The inside of a battery pack body 1 is set in size and length to have a space accommodating batteries and a compensating circuit 3. A battery holder 4 is arranged between the compensating circuit 3 and the batteries. The battery holder 4 has abut sections 5, 6 abutting on inner walls in the width direction of the battery pack body 1 and a battery pad section 8. Step sections 11, 12 are provided face to face on inner walls in the longitudinal direction of the battery pack body 1, and vacant sections 13, 14 are provided on the side where the battery holder 4 is arranged. The battery holder 4 is fixed in the battery pack body 1 in a half-fixed state while a space, where the compensating circuit 3 is arranged, is formed by the steps 11, 12. |
