ABSTRACT:
A closed secondary battery having a sealing structure for preventing electrolyte leak for a long period is presented. An annular packing is chemically bonded in a ring form to the surface of a disk-shaped flange formed inside of a battery of a terminal pole projecting from inside to outside of the battery, by penetrating through a cover member of closed secondary battery. Fitting an annular spring while pulling the terminal to outside of the battery, the terminal pole is fixed in the cover member. At this time, the annular packing is compressed against the cover member, and the passage of electrolyte leak is shut by this compression.
