A battery tray is fixed onto a front battery cross member lower and a rear battery cross member lower. The battery pack is mounted on the battery tray. The front battery cross member lower and the rear battery cross member lower come into contact with a deformable zone of the battery tray and the end face of each of battery cross member uppers at attachment portions. Space is created between the battery pack and the battery cross member uppers. The battery cross member uppers are welded so that a deformable zone having relatively low rigidity is formed. In this way, the front battery cross member lower and the rear battery cross member lower are fixed to a pair of side members through the battery cross member uppers.

Battery installation structure for electric vehicles

A battery casing for receiving a battery for driving an electric vehicle, including: a tray member made from a resin and supporting the battery; a support member provided under a lower face of the tray member and supporting the tray member from a bottom thereof; a standing wall provided so as to stand in the tray member; and a sheet metal tray member made from a sheet metal and placed on the tray member. The sheet metal tray member includes a plurality of sheet metal recesses that receive the battery and a sheet metal flange placed on an upper face of the standing wall. The standing wall includes a through hole formed through the standing wall in a standing direction of the standing wall. The support member and the sheet metal flange are fastened to the tray member by a sheet metal fastening member provided through the through hole.
