PROBLEM TO BE SOLVED: To provide an on-vehicle power storage device of which the vibration resistance is improved.SOLUTION: A power storage device includes: power storage elements which are angular power storage elements and aligned in a first direction; and an internal spacer 2A which is disposed between the power storage elements. The internal spacer 2A includes: a base 20A with which the power storage elements are disposed at both sides in the first direction; and a regulation part 21A which is abutted with one end of the power storage elements in a second direction orthogonal with the first direction and suppresses the positional displacement of the power storage elements relative to the base 20A. The regulation part at one end side includes: a first confronting portion 2111 including a confronting surface 2111A that confronts one end face of the power storage element; a pair of second confronting portions 2112 holding one end of the power storage element therebetween in a third direction orthogonal with the first and second directions; and a projection 2114 which protrudes from the confronting surface to the one end face of the power storage element and extends in the third direction.SELECTED DRAWING: Figure 6 |
