PROBLEM TO BE SOLVED: To suppress a battery module from being tilted downward in a vertical direction, the battery module being installed in a member extending in the vertical direction.SOLUTION: One end surface of a weight body 33 in the thickness direction serves as an installation surface 33a where battery modules 60 are installed. The plurality of battery modules 60 are provided on the installation surface 33a. A heat conduction member 70 is provided between each of the battery modules 60 and the weight body 33. When the heat conduction member 70 is divided into two at the center C in a vertical direction before the battery modules 60 are installed on the weight 33, the volume of the lower part 71 in the vertical direction is greater than the volume of the upper part 72 in the vertical direction. |
