Abstract
A power storage device includes: a power storage stack; paired end plates; paired side covers; an upper constraint member; and a lower constraint member. The power storage stack has: a first stack; a second stack; and an intermediate plate. The paired side covers each have an intermediate engagement portion that engages with the intermediate plate, and paired side end engagement portions that laterally engage with the paired end plates, respectively. The upper constraint member constrains the power storage stack, while permitting the intermediate plate to move relative to the upper constraint member in the one direction, and the lower constraint member constrains the power storage stack, while permitting the intermediate plate to move relative to the lower constraint member in the one direction.
