Abstract: A sealing body of a cylindrical battery, including: a sealing plate with a through-hole formed at a center of a metallic disk and a thin-walled portion formed into a groove in a planar surface of the disk, the sealing plate mounted to a cylindrical battery can having a closed bottom, so as to seal an opening of the battery can, the battery can doubling as an electrode current collector of either a positive or negative electrode and housing a power generating element; an electrode terminal of another of the positive or negative electrode, the electrode terminal including a shaft portion inserted into the through-hole and fitted to the sealing plate; and a sealing gasket made of resin and interposed between the shaft portion and the through-hole. The thin-walled portion has an arc shape and is not formed along a circle concentric with an outer periphery of the sealing plate.

Abstract: A sealing member 40 to seal an opening of a battery can, the sealing member being used to configure a tube-shaped battery provided with a bottomed tube-shaped battery can and a power generating element that has been arranged inside the battery can, the sealing member 40 includes an electrode terminal that is to be electrically connected to the power generating element, a sealing plate 41, insulating gaskets 42a, 42b, and a washer 44. An inserting part 43b extending from the electrode terminal 43 is inserted through these elements so that the elements are integrally tightened. The insulating gasket 42a is provided with a protruding part 42a1 having an appropriate horizontal section shape, and the sealing plate 41 adjacent to the insulating gasket is provided with a recess part 41a that has been formed in a shape corresponding to the protruding part 42a1.
Abstract translation: 用于密封电池壳体的开口的密封构件40，密封构件用于构造设置有底管状电池罐的管状电池和布置在电池壳内的发电元件，密封件 构件40包括要电连接到发电元件的电极端子，密封板41，绝缘垫圈42a，42b和垫圈44.从电极端子43延伸的插入部分43b通过这些元件插入 元件被整体拉紧。 绝缘垫圈42a设置有具有适当水平截面形状的突出部分42a1，与绝缘垫圈相邻的密封板41设置有形成为与突出部分42a1对应的形状的凹部41a。

Abstract: A sealing body for sealing an upper opening of a battery can having a tube shape with a closed bottom includes an electrode terminal, a sealing plate, and gaskets. The electrode terminal includes a flat plate-shaped stepped portion in an area of a lower surface of a flat plate-shaped terminal portion. The electrode terminal has an inserting portion extending downward in a columnar shape on a lower surface of the stepped portion, and a protrusion in a non-circular planar shape that goes around the inserting portion. The sealing plate has an opening, and has an upper surface and a lower surface on which a non-circular sealing-plate recessed portion and a sealing-plate protruding portion are formed. The gaskets have a shaft portion inserted through the opening of the sealing plate, and a protruding portion that engages the sealing-plate recessed portion and a recessed portion that engages the sealing-plate protruding portion.
