Abstract
An electricity storage device according to the present invention includes a battery module having side plates and cover members assembled to both the sides of a case member of the battery module, so that gas discharge spaces are defined into which gas is emitted from the terminals of battery cells that are stored within the case member. Projecting portions are provided to the side plates respectively, and have through-holes communicating with the gas discharge spaces. The lowermost surfaces of the through-holes of the projecting portions are positioned lower than a axe of any of the battery cells. The projecting portions are connected by a tubular rubber members.
