<p>PROBLEM TO BE SOLVED: To layer a plural number of batteries outer peripheral surfaces of which are formed of an electrically conductive material while securing insulation and to uniformly cool each of the batteries. SOLUTION: A battery holding part 36 to match with an outer peripheral part of the battery 20 is formed on outer edge parts 32, 34 of a battery holder 30 formed of resin, an opening space 48 is formed of a plural number of ribs 46 so that a channel of cooling air is formed when it is layered with the battery 20, and communicating outer edge parts 42, 44 are formed so that an opening part communicated to the opening space 48 as this channel of cooling air is formed. It is possible to secure insulation of the battery 20 even when the outer peripheral surface of the battery 20 is formed of the electrically conductive material as the battery 20 is held by the battery holder 30 formed of resin. Additionally, it is possible to cool the battery 20 by supplying cooling air to the channel of cooling air to be formed at the time of layering the battery 20 and the battery holder 30 through the opening part that communicates with the channel.</p> |
