<p><P>PROBLEM TO BE SOLVED: To provide a battery pack capable of reducing noises leaked to the outside. <P>SOLUTION: The battery pack 10 is formed by arranging a plurality of chargeable and dischargeable single batteries 20 at a designated direction. A spacer 40 having a contact section 42 brought into contact with at least one of the single batteries and a noncontact section 44 extended in a planar state without bringing into contact with any batteries is arranged between the adjacent single batteries. A plurality of through-holes 46 are arranged on the noncontact section 44, and air gaps 47 and 49 connecting with the through-holes 46 are respectively formed on both sides of the noncontact section 44. Thus, the noises, if any, generated from the single batteries, are absorbed by making use of the through-hole 46 of the noncontact section 44 and the air gap 47 arranged on its back surface disposed at a right side of the single battery 20, and the noises leaked to the outside of the battery pack 10 can be restrained. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
