<p>PROBLEM TO BE SOLVED: To prevent the collision of built-in batteries against a main body during use and the generation of collision sounds by making mold structures for the main body and cap simpler and advantageous for the manufacturing cost and life of molds. SOLUTION: The outer flank of a cap side peripheral wall part is provided with a cap side engaging part consisting of a plurality of rugged lines. The cap side peripheral wall part is provided with a pair of elastic bodies 116 for elastically energizing two pieces of the batteries 12 to a central side with each other and either of a pair of cap side terminal members 130 is extended and provided with a contactor 142 parted and positioned on another lower side surface. The brush is provided with a switch body 156 having an arm part 164 which is actuated to an on position and off position beyond a nodal projection of a changeover rib cooperatively to a lever part 160 actuated to the on position and the off position to bring the contactor into contact with the other cap side terminal member and to part the same therefrom.</p> |
