止構造を有した鉛蓄電池を提供することにある。Problems to be Solved by the Invention Recently, a mold with a concave portion formed on the top surface was prepared, molten lead was placed in the concave portion, and the leading end of the electrode plate was immersed in the molten vessel to form a strap. The so-called cast-on strap method for forming a cast-on strap has come to be widely used, but if the pole has a sharp flange like the conventional method, the cast-on strap mold is must be formed into three parts. In other words, in order to prevent casting burrs from forming at the location where the O-ring of the pole post is installed, the first mold 15 is formed so that the product can pass through upward, and the pole pole is placed in contact with the top surface of the mold 15. A second mold 17 and a third mold 18 that open left and right and are formed so that the protruding flange 16 can be removed upwardly are required. This not only makes the mold and the equipment that operates the mold extremely complex, but also causes molten lead to scatter during manufacturing, resulting in lead ingots frequently getting caught between the split molds. The actual situation is that cast-on strut equipment with a split mold configuration cannot be put to practical use because the work of removing the cast-on struts one by one becomes a major obstacle. SUMMARY OF THE INVENTION An object of the present invention is to provide a lead-acid battery having a sealing structure for the pole column penetration portion of the lid, which can be formed without splitting the mold of the cast-on strap.

挟持されたものである。Means for solving the problem The present invention is! 5, a pole post 7, and an O ring 10,
Said! The pole 5 has a small pole through hole 5 and a major pole through hole 6, and the pole 7 has a major pole 7a, a step 8 on the top of the major pole 7a, and an upper part of the step 8. The O-ring 10 is annularly formed of soft rubber, and the small pole through hole 5 passes through the small pole 9 and the large pole The pole pillar through hole 6 allows a part of the small pole pillar 9 and a part of the big pole pillar 7a to pass through, and the O-ring 10 has an outer diameter larger than the inner diameter of the big pole through hole 6, and an inner diameter of the O ring 10. It is formed smaller than the outer diameter of the small pole pillar 9, and is sandwiched between the small pole pillar 9 above the large pole through hole B and near the top of the step 8.

鉛直方向へ抜ける。The working pole is composed of a cylindrical large pole and a cylindrical small pole that further protrudes above the step provided at the top of the large pole, and the outer diameter of the small pole is equal to the large pole. Since the outer diameter of the pole column is smaller than the outer diameter of the cast-on strap, the pole column can be pulled out in the vertical direction without forming the cast-on strap mold into a split mold.

is formed. The upper end corner 3 of the large pole through hole 6
a is in the form of a circular arc, and the lower end corner 3b is inclined. The small pole through-hole 5 and the large pole through-hole 6 are formed in concentric circles. 7 is a pole, and the pole 7 has a cylindrical major pole 7a. An arcuate step 8 is provided at the top of the pole pillar 7a, and a small pole pillar 9, which is a cylinder having an outer diameter smaller than the large pole pillar 7a, projects above the step 8. The upper end 9a of the small pole pillar 9 is inclined. The large pole pillar 7a and the small pole pillar 9 are formed in concentric circles. The large pole 7a is formed so that it can be inserted into the large pole through hole 6 with a certain gap, and the small pole 9 is also inserted into the small pole through hole 5. Although it is formed in such a way that it is possible to
It is smaller than the gap between the large pole pillar 7a and the large pole through hole 6, and is made as small as possible. Reference numeral 10 denotes an O-ring made of soft rubber, and when installed at a predetermined position (as shown in FIG. That is, the annular outer diameter of the O-ring 10 is larger than the inner diameter of the large pole through hole 6, and the inner diameter is smaller than the outer diameter of the small pole 9.

When a product is formed by the cast-on drag method, the product can be pulled upward as it is, and there is no need to split the cast-on drag mold. In addition, since the upper end of the small pole pillar is sloped, it is possible to easily insert the small pole pillar into the small pole through hole of the lid, and to reduce the gap between the small pole pillar and the small pole pillar through hole. Since it is made as small as possible,
The deflection of the pole pillar can be kept to a minimum, and as a result, the pole pillar penetrating portion of the lid can be sealed well.
