Patent ID: 8790813

Claim:
An electric storage apparatus comprising: a plurality of electric storage components; and a holder comprising a holder body and a holder cover, the holder holding each of the electric storage components at both end portions of each of the electric storage components in a longitudinal direction, wherein each of the electric storage components includes electrode terminals at the both end portions, and a section shape of each of the electric storage components within an orthogonal plane orthogonal to the longitudinal direction of the electric storage component is formed in a generally circular shape, wherein the holder body including: a plurality of guide portions provided within the orthogonal plane and configured to move both end portions of each of the electric storage components toward a predetermined holding position; and an opening portion formed within the orthogonal plane at an upper end of each of the guide portions and configured to insert the end portion of the electric storage component into the guide portion, wherein the opening portion of the holder is located above the electric storage components when viewed from the longitudinal direction of the electric storage components, the holder cover is provided over the opening portions to close the upper ends of the guide portions in a direction orthogonal to the longitudinal direction of the electric storage component, wherein the plurality of electric storage components include first and second electric storage components each having a stage for the electrode terminal, the stages having different outer diameters, and wherein the guide portion includes a pair of first guide regions and a pair of second guide regions, the second guide regions located on the side of the first guide regions opposite to the opening portion, wherein the stage having a larger outer diameter is arranged between the pair of the first guide regions and is in contact with the first guide region, wherein the stage having a smaller outer diameter is arranged between the pair of the second guide regions and is in contact with the second guide region.
