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