であった。Conventional technology Conventionally, in sealed storage batteries, in order to prevent self-discharge due to oxygen gas flowing into the battery from outside the battery melter and to prevent dilute sulfuric acid, which is an electrolyte, from flowing out of the battery container, other parts other than the safety valve were used. requires complete sealing. For this reason, a method of sealing 4 poles and pillars has been adopted. After making an opening at the bottom of the recess provided in the lid and passing the pole column through this opening, the annular rib that stands above the periphery of the opening is heated and melted, and the molten resin creates a polarity and an opening. There is a method of sealing the pole by sealing the gap between the lid and the recess of the lid, and then filling the recess of the lid with adhesive, or by inserting the pole into the opening made at the bottom of the recess of the lid for 1 m, and then inserting it from a rubber backing, etc. There is a method of fitting a filler material to the pole pillar, covering the gap between the opening and the pole pillar from above, and filling the recess with adhesive to surround the pole pillar to seal the pole pillar. It was representative.

。Problems to be Solved by the Invention Among these conventional methods, the former method is to close the gap between the pole pole and the opening provided in the lid after the synthetic resin battery case and lid are welded together. , the process becomes complicated, and since the annular rib provided in the recess of the lid is heated and melted, the adhesive wraps around and the surface area of the pole changes, resulting in insufficient adhesive elasticity and easy peeling of the adhesive. There was a problem in that the probability of leakage of dilute sulfuric acid, which is an electrolytic solution, was high. On the other hand, in the latter method, a sealing material such as a rubber backing is used, which has the problem of increasing the cost of parts and the number of man-hours.
本発明は、このような問題点を解決するものであって、
作業性よく極柱部分を密封できる信頼性の高い極柱封止

を確保している。In order to seal the pole column 3 connected to the electrode plate group with the lid 1,
First, it is necessary to thermally weld the battery case 6 and the lid 1 together. FIG. 1 shows a hot plate main body 9 and an upper hot plate 10. Lid 1 and battery case 6 with lower heating plate 11 in between
It is a preparation state diagram where the two are arranged to face each other. At this time, the upper hot plate 1o is provided with a protrusion 12 that penetrates the opening 2 of the lid 1 and prevents the opening from being filled with molten resin. Further, the lower heating plate 11 is provided with a recess 13 to prevent the pole pillar 3 from colliding with it. An annular rib 14 extending downward is provided on the inner periphery of the opening 2 of the lid 1 to ensure enough resin to close the gap between the pole and the opening.
