PURPOSE:To produce an enclosed type storage battery in which low-viscosity sealing resin can be used by inserting and welding a terminal electrode pole having a large diameter into a through hole formed in the recess of a battery jar cover while generating ultrasonic vibrations, welding a battery jar and the battery jar cover with ultrasonic waves, then filling the recess with sealing resin. CONSTITUTION:A terminal electrode pole 4 made of a lead alloy and having an outer diameter D2 larger than the inner diameter D1 of a through hole 3 is inserted into the through hole 3 formed in the recess 2 of a cover 1 while a battery jar made of synthetic resin is vibrated by ultrasonic waves, thereby the terminal electrode pole 4 is welded to a flange 5 forming the through hole 3. At the same time, a battery jar 6 and a battery jar cover 1 made of synthetic resin are welded by ultrasonic waves. Next, after an extracting terminal 7 is welded to the upper section of the terminal electrode pole 4, the recess 2 is filled with sealing resin 8. Silicon rubber or the like having low viscosity can be used as the resin 8. |
