Abstract: A pressure regulating valve is attached to each of a plurality of power storage modules. The pressure regulating valve allows internal spaces of the power storage modules to be open, respectively, and has a short-circuit preventing structure for preventing an electrolytic solution coming outside of the power storage modules from causing a short circuit with another power storage module or a short circuit between other power storage modules.
