があった。[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sealed lead-acid battery equipped with a battery case whose side walls in the direction of lamination of electrode plates are reinforced. Storage battery cases are usually made of polypropylene resin. Insert the electrode plate group into this with a large insertion load,
When an electrolyte is injected after the battery is completed, the electrode plates swell and the internal pressure of the battery increases. Due to this combined effect, the side wall of the battery case located in the direction in which the electrode plates are stacked bulges outward. In order to prevent this, for example,
As shown in Publication No. 2, on the outside of the container wall parallel to the electrode plate,
It has been proposed to integrally embed or fix a reinforcing material made of metal or the like. However, in the case of metal, the most suitable material is mild steel plate, which is cheap and easy to obtain, but since it is not acid resistant, it will corrode early if exposed. To prevent this, it is necessary to The reinforcing material made of the above-mentioned mild steel plate must be buried so that its entirety is not exposed, but in order to form it in this way, it is necessary to support the reinforcing material with a mold for forming the battery case. However, it is extremely difficult to support it without exposing it, and there is a drawback that it is virtually impossible to industrialize it.

に、作業を容易に行うことが出来る。The reason why mild steel plate is used is that it is the most suitable material because it has a tensile strength about 10 times that of polypropylene resin and is available at a low cost. Further, the width of the mild steel plate 18 is formed to be approximately the same as the width of the electrode plate (FIG. 4). In order to double mold the mild steel plate 18, as shown in FIG.
A mild steel plate 18 is attached to the bottom wall surface 15d of the concave portion 15c of b, and then an injector Vg7 blade 19.19' is applied and pressed so as to sandwich the V-side wall 15b as shown in the figure.
Next, polypropylene resin is injected from the sprue liner 19a. When the same resin as the battery case prepared in advance is injected in V-sealing mode, the injected resin (the part indicated by the many dots) melts and bonds at the point where it contacts the battery case 11 and covers the entire mild steel plate 18. It will be completely covered. In other words, the mild steel plate 18 is integrally buried within the side wall 15a. Effects of the Invention As described above, the present invention is capable of injecting reinforcing material into the inside of the battery case@wall by the Vw:/mode method. Since the reinforcing material is buried, there is no need to support the reinforcing material with a battery case molding die, and the work can be performed easily.
