Battery casing

A battery casing for receiving a battery for driving an electric vehicle comprising:

• 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,
• wherein the sheet metal tray member comprises a plurality of sheet metal recesses, including a bottom plate, that receive the battery and a sheet metal flange protruding outwardly in a horizontal direction from an upper end of the front plate and the rear plate, and placed on an upper face of the standing wall, the bottom plate receiving a bottom of the battery,
• the standing wall comprises a through hole formed through the standing wall in a standing direction of the standing wall, and
• the support member and the sheet metal flange are fastened to the tray member by means of a sheet metal fastening member provided through the through hole.
• wherein the battery comprises a battery flange placed on the upper face of the standing wall,
• the support member and the battery flange are fastened to the tray member by means of a battery fastening member provided through the through hole, and
• the sheet metal fastening member and the battery fastening member are arranged side by side, and
• wherein the sheet metal fastening member and the battery fastening member each include a through nut inserted in the through hole and a bolt,
• the support member and the sheet metal flange, and the support member and the battery flange are fastened to the tray member once the bolt is screwed with the through nut from the upper face of the standing wall and the lower face of the tray member,
• the bottom plate of the sheet metal tray member is made of the sheet metal, and
• the sheet metal tray member is made of a single piece member.
