<P>PROBLEM TO BE SOLVED: To improve a protection function for an electrode terminal prepared in a battery pack. <P>SOLUTION: A side-viewed L-shaped case body 10 is formed of a long sideways main case section 21 and a sub-case section 22 projected in the direction orthogonal to the main case section 21. Electrode terminals 50A, 50B mounted on a circuit board 40 are positioned within an imaginary line B between the tip of the main case section 21 and a projecting end of the sub-case section 22, and are arranged at a sub-case section side of the main case section 21. Slits 211A, 211B capable of making a main body side electrode terminal 180 of a driver drill 100 enter into the case body 10 are formed on the main case section 21 in response to respective electrode terminals 50A, 50B. <P>COPYRIGHT: (C)2009,JPO&INPIT |
