Abstract
(EN)
An objective of the present disclosure is to provide a gasket and cylindrical battery such that a short-circuit of a lead part can be suppressed and workability at time of assembly can also be improved. A gasket (28) of a cylindrical battery according to an embodiment of the present disclosure comprises a cylindrical part (60), and a ring part (61) which extends from one end part of the cylindrical part (60) in the axial direction toward an inner side thereof in the radial direction. A surface (67) of the ring part (61) which is opposite the cylindrical part (60) side in the axial direction has an approximately flat surface. A protrusion (57) is provided on the side of the ring part (61) which is toward the cylindrical part (60) in the axial direction. Said protrusion (57): is positioned with gaps in the radial direction in relation to both the cylindrical part (60) and an inner end (69) of the ring part (61) in the radial direction; and protrudes in the axial direction.

Un objectif de la présente invention est de réaliser un joint d'étanchéité et une batterie cylindrique de telle sorte qu'un court-circuit d'une pièce en plomb peut être supprimé et l'aptitude au façonnage au moment de l'assemblage peut également être améliorée. Un joint d'étanchéité (28) d'une batterie cylindrique selon un mode de réalisation de la présente invention comprend une partie cylindrique (60) et une partie annulaire (61) qui s'étend depuis une partie d'extrémité de la partie cylindrique (60) dans la direction axiale vers un côté interne de celle-ci dans la direction radiale. Une surface (67) de la partie annulaire (61) qui est opposée au côté de la partie cylindrique (60) dans la direction axiale a une surface approximativement plate. Une partie saillante (57) est disposée sur le côté de la partie annulaire (61) qui est vers la partie cylindrique (60) dans la direction axiale. Ladite partie saillante (57) : est positionnée avec des espaces dans la direction radiale par rapport à la fois à la partie cylindrique (60) et à une extrémité interne (69) de la partie annulaire (61) dans la direction radiale ; et fait saillie dans la direction axiale.
