An electric motor receives electric power from an electricity storage module. A drive target is driven by the electric motor. The electricity storage module has a plurality of protection plates, which are stacked up in a stacked direction, and a plate-shaped electricity storage cell, which is interposed between the protection plates adjacent to each other. The protection plates have a positional restriction shape for restricting a relative position with respect to a positional restriction direction which is perpendicular to the stacked direction. |
