Therefore, it is possible to prevent the connecting wall from collapsing when the seal portion is kept airtight from the battery. Therefore, it is possible to more reliably prevent the pair of walls from falling when the seal portion contacts the battery and keeps the space between the battery and the battery airtight. Therefore, the space between the seal portion and the battery can be surely kept airtight, and the gas generated from the battery can be more surely prevented from leaking to the outside of the power supply device other than the discharge path.
