Document Type and Number:
Japanese Patent JP5772348
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a battery and the like, in which pressure inside a battery case is properly reduced.SOLUTION: In a battery 100, a possible range of a sufficient pulling yield strength Fa when a rubber plug part 183 is pulled under an atmospheric pressure Pa while an internal pressure of a battery case 110 is the atmospheric pressure Pa is designated as a first yield strength range AFa, and a possible range of a sufficient pulling yield strength Fb when the rubber plug part 183 is pulled under the atmospheric pressure Pa while an internal pressure of the battery case 110 is an initial internal pressure Pb is designated as a second yield strength range AFb, an inside diameter d of a cylindrical part 171 of a through hole 170, an outside diameter D of a maximum compression part 183p of the rubber plug part 183, and hardness H of the rubber plug part 183 are arranged so that the first yield strength range AFa is spaced from the second yield strength range AFb.
