Abstract: A power storage module includes at least one power storage device, and a buffer member arranged with the power storage device in a first direction X. The buffer member includes a hard part having a predetermined hardness and a soft part softer than the hard part, the hard part and the soft part receiving a load in first direction X from the power storage device. The hard part changes its shape by receiving a load of a predetermined magnitude or more. The buffer member changes its state, by the hard part changing its shape, from a first state in which the load is received by the hard part to a second state in which the load is received by the soft part.

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.
