Abstract:
A battery-affixing frame member includes a body plate section and duct-forming members. The duct-forming members are affixed to one surface side of the body plate section and are combined with the body plate section to form gas discharge ducts. The gas discharge ducts are used to discharge gas discharged from the inside of battery modules. The battery-affixing frame member is used to form a battery-affixing member for integrally affixing the battery modules together, the battery modules being arranged on the other surface side of the body plate section.
