ABSTRACT:
A sealed secondary cell maintaining enclosed property and battery performance for a long period in a wide range of environments of use including high temperature, high humidity, and vibration is presented. A terminal pole is composed of a current collector, a flange with a flat top surface, and a pole formed on the flange upper surface projecting at right angle, a rotation arresting portion of the terminal pole is formed by the flange and lower side of a lid, an annular packing is disposed between the flange upper surface and lid lower side so as to surround the pole, an annular pressing spring is pressed in from above the pole, the annular packing interposed between the flange upper surface and lid lower side is compressed in the vertical direction by the elastic force of the annular pressing spring, the annular pressing spring is stopped on the outer circumferential edge of the pole at a position for sealing and fixing the terminal pole in the lid, and thereby the battery jar is enclosed.
