PURPOSE:To stabilize and improve airtightness by mounting a metallic sealing plate on a cylindrical part and bending a case opening part inward and sealing this part and pressing/fixing a cylindrical flange-fitted insulation fixed frame 8 by the use of an insulation gasket. CONSTITUTION:A hollow cylindrical part 8a of an insulation fixed frame 8 is formed unitedly with a flange part 8b which is installed under the peripheral part of the part 8a. A metallic sealing plate 2 with an insulation gasket 3 incorporated on its periphery is mounted as a positive electrode terminal on the cylindrical part, and next a cylindrical flange-fitted insulation fixed frame 8 is pressed/fixed by the use of the insulation gasket 3. Then, the hollow cylindrical part 8a functions to push up its part in contact with the insulation gasket 3, and the insulation gasket 3 is sticked fast to the whole peripheral surface of the metallic sealing plate 2, so that the fast sticking region can be remarkably enlarged. |
