Beschreibung
Zusammenfassung:	Provided herein is an electrical storage device that can reduce fluctuations in pressing force applied to different portions of an insulating ring member. Eight projections 19c are integrally provided on a surface of a plate-like portion 19b of an insulating ring member 19, which opposes an annular projected portion 15, to contact the annular projected portion 15. The projections 19c are disposed at constant intervals in the circumferential direction of an axial core 11. The projections 19c are each shaped to extend in the radial direction of the axial core 11, and each have a length to project inwardly of a top portion 15a of the annular projected portion 15 in the radial direction of the axial core 11, being in contact with the annular projected portion 15.
