を閉蓋する上ぶた８を有している。The specific structure is that a flat valve seat 4 is provided on the bottom of the upper recess 3 of the inner lid 2 that covers the upper opening of the battery case 1, and an exhaust port 6 that communicates with the cell chamber is provided on this valve seat. A rubber sheet-like valve 6 that blocks this exhaust port and a cushion material 7 that elastically pressurizes this sheet-like valve are held from above, and the recessed portion 3
It has an upper lid 8 for closing.
通常蓄電池が完成した状態で密閉形蓄電池の気密性を確
認する手段としては排気口を覆っている弁の電槽内部が
減圧によって生じる弁体の凹球面の発生状態を検視して
いた。Normally, a means of checking the airtightness of a sealed storage battery when the battery is completed is to inspect the concave spherical surface of the valve body, which is caused by depressurization inside the battery case of the valve that covers the exhaust port.
発明が解決しようとする問題点
しかしシート状弁６がクッション材７及び上ぶた８で覆

あった。Problems to be Solved by the Invention However, since the sheet-like valve 6 is covered with the cushion material 7 and the upper lid 8, the occurrence of the concave spherical surface cannot be confirmed. This had to be done at the product stage. As a result, it was impossible to discover any problems that might occur during the post-mortem process, and great care had to be taken to ensure that the airtightness would not be compromised even when the cushioning material was placed and the top lid was ultrasonically welded.

し、これらを案内する構成である。Reference numeral 6 designates an exhaust port provided at the center of the top of each cell chamber 9 of the lead-acid battery (the partitions between the cell chambers are not shown) of the planar valve seat 4. Reference numeral 6 denotes a rubber sheet-like valve that is in close contact with the valve seat 4 and has the exhaust port 4 hermetically closed. Reference numeral 7 denotes a cushioning material that elastically and uniformly presses the sheet-like valve 6 from above. This cushioning material 7 is further covered with a transparent top lid 8 from above, and both sides of the transparent top lid 8 are covered with an inner lid 2. It is welded and fixed to the stepped portions 1o provided on both sides of the recessed portion 3. Reference numeral 11 denotes a plurality of guide ribs provided on the inner wall of the recess 3, and each guide rib 11 includes:
The upper part has a tapered part, which is provided facing each other from both sides, and the inner side thereof faces the outer surfaces of the seat valve 6 and the cushion material 7 described above, and is configured to guide them.
１２は、前記クッション材７に貫通させた検視窓で排気
口６の上方にこれと園心円状でや５太き目に形成する。Reference numeral 12 denotes an inspection window penetrated through the cushion material 7, and is formed above the exhaust port 6 in the shape of a circle with a diameter of 5 mm.
