雑になり、生産コストも高くなるという欠点があつた。Conventionally, as a method of exhausting a closed type storage battery containing a monoblock battery without a free electrolyte solution, the gas generated in each cell is collected in an exhaust chamber and then exhausted to the outside of the storage battery through an exhaust hole. In this method, however, a recess is formed in the upper surface of the lid to ensure liquid-tightness between the cells, and the inner lid for forming the exhaust chamber is heat-welded or adhered to the recess with an adhesive. However, the manufacturing process is complicated and the production cost is high.

11 ″ is inserted to connect the poles between cells of the electrode plates of adjacent cells 12
After welding and connecting the upper part of the above, the upper part of the inter-cell connecting pole 12 is double injection-molded by the synthetic resin molding machine to prepare the double injection part 22, and as shown in FIG. Inclined notch 6 of part 7
After fitting the fitting groove 13 of the exhaust gas collecting wall 14 into the above, the exhaust gas collecting wall 14 and the exhaust gas collecting wall joint portion 5 are ultrasonically welded to each other to form the exhaust gas collecting chamber 15, and after that. Battery case 2
The heat-sealing of the upper part of 5 and the lower part of the lid 9 completes the manufacture of the sealed storage battery 1 according to the present invention. Reference numeral 23 is an ultrasonic welding portion, and 24 is a heat welding portion. The battery case 25

自己放電は防止できる。Further, in the above ultrasonic welding, welding of the slanted cut portion 6 and the fitting groove 13 cannot be expected so much, but the sealed storage battery according to the present invention allows free electrolysis by absorbing the electrolytic solution in the glass mat and the separator. Since the liquid is eliminated, even if there is some gap in the cell-to-cell connection portion, self-discharge due to leakage at the portion can be prevented.

Further, by providing a fitting groove on the exhaust gas collecting wall and fitting it into the partition wall portion of the lid, the side surface of the partition wall portion that cannot be ultrasonically welded can be brought into close contact, and the leak cell between adjacent cells of the portion can be closely contacted. Since the bread is long, self-discharge due to leakage can be prevented.
