To provide a layout structure of a power storage device in which displacement of a restraint plate upon power storage module expansion is suppressed while avoiding an increase in weight.SOLUTION: A layout structure 1A of a power storage device 1 is a layout structure 1A of the power storage device 1 for a vehicle. The power storage device 1 comprises one or a plurality of power storage modules 4 consisting an electrode laminate body 11 in which electrodes are laminated with interposed separator 13, and a pair of constraint plates 8 that sandwich the power storage modules 4 in the lamination direction Z of the laminate body and apply a constraint load to the power storage modules 4 in the lamination direction Z. The power storage device 1 is arranged in the vehicle such that the distance between a vehicle frame member 30 and the constraint plates 8 is lower than the maximum displacement level of the constraint plates 8 in the lamination direction Z upon expansion of the power storage module 4.SELECTED DRAWING: Figure 4

    【課題】重量の増加を回避しつつ、蓄電モジュール膨張時の拘束板の変位を抑制できる蓄電装置の配置構造を提供する。【解決手段】蓄電装置1の配置構造1Aは、車両に対する蓄電装置1の配置構造1Aであって、蓄電装置1は、セパレータ13を介して電極が積層された電極積層体11を含んで構成される一又は複数の蓄電モジュール4と、蓄電モジュール4を積層体の積層方向Zに挟み、蓄電モジュール4に積層方向Zの拘束荷重を付加する一対の拘束板8と、を備え、車両の骨格部材30と拘束板8との間隔が蓄電モジュール4の膨張時における拘束板8の積層方向Zの最大変位量未満となるように、蓄電装置1が車両内に配置されている。【選択図】図4
