Abstract: An electric power storage module includes an array body in which a plurality of electric power storage devices are arranged in a first direction, a pair of end plates which are disposed at both ends of the array body to interpose the array body, and a first binding member and a second binding member which bind the array body in the first direction. The first binding member includes a first main body extending in the first direction and a pair of first protrusions protruding from both ends of the first main body toward the end plates and fixed to each end plate. The second binding member includes a second main body extending in the first direction and a pair of second protrusions protruding from both ends of the second main body toward the end plates and fixed to each end plate. At least a portion of the first protrusion and at least a portion of the second protrusion overlap each other in the first direction to form an overlapping section.

Abstract: A power storage module includes an array including power storage devices each having first and second surfaces opposite to each other in a first direction, a first restraint member facing the first surface of each power storage device, and a second restraint member facing the second surface of each power storage device. Dimensions of the power storage devices in a second direction perpendicular to the first direction are larger than respective dimensions of the power storage devices. The power storage devices are arranged in a third direction perpendicular to the first and second directions. The first restraint member extends in the third direction and restrains the array in the third direction. The second restraint member extends in the third direction and restrains the array in the third direction. At least one of the first and second restraint members has a hole therein. The hole is a recess falling in the first direction or a through-hole passing through the restraint member in the first direction.
