Title: POWER STORAGE DEVICE
Abstract:
A power storage device is provided with a case having a wall part, an electrode assembly accommodated within the case, an electrode terminal, a first insulation member, a second insulation member, and an annular seal member. The electrode terminal has a base part and a pole post part. The first insulation member is interposed between the inner surface of the wall part and the seating surface of the base part. The second insulation member is interposed between the inner circumferential surface of an insertion hole and the outer circumferential surface of the pole post part. The seal member is interposed between the inner surface of the wall part and the seating surface of the base part, and is disposed inside a through hole in the first insulation member. The second insulation member has a tip section inserted between the inner circumferential surface of the seal member and the outer circumferential surface of the pole post part. The tip section is configured so as to make contact under pressure with the inner circumferential surface of the seal member and to cause the seal member to make contact under pressure with the inner circumferential surface of the through hole in the first insulation member.
