を持つものが殆んどになってきている。Conventional configurations and their problems Recently, the number of maintenance-free lead-acid batteries that do not require fluid replacement has been increasing, and with this, most of the liquid plugs have an explosion-proof function.
以下従来の鉛蓄電池について第１図、第２図。Figures 1 and 2 of conventional lead-acid batteries are shown below.

薄肉部８を押し破りセンサーを取り付けていた。FIG. 2 is a sectional view taken along the line AA in FIG. 1, and is an enlarged sectional view of the sensor mounting portion 4. FIG. Reference numeral 5 denotes a threaded tube portion provided through the lid 2, and reference numeral 6 denotes a temporary liquid port plug attached via a rubber gasket 7 to close the screw tube portion 5. With this configuration,
When attaching the sensor to this lead-acid battery, the temporary liquid port plug 6 was removed and installed. However, in this case, the temporary liquid port plug 6 and the rubber gasket 7 must be provided separately, which significantly increases the material and cost. However, this is extremely wasteful in terms of productivity and cost, and if the temporary liquid port plug 6 is accidentally reattached to the threaded tube portion 6 after the sensor has been installed, the battery may explode. FIG. 3 is a cross-sectional view taken along the line AA of the sensor mounting portion 4 shown in FIG. 1, which is another conventional example that has been made to solve the above-mentioned problems. The same numbers as those in FIG. 1 are given to the same sections. Reference numeral 5 denotes a threaded cylindrical portion provided on the lid 2, and the bottom surface is provided with a thin wall portion 8 that is thinner than the wall thickness of the lid 2. When installing the sensor, this thin wall portion 8 was broken and the sensor was installed. .

いかない等、信頼性の面で多くの問題があった。According to this configuration, there is no need for temporary liquid spout plugs or rubber seals, and the number of assembly steps can be reduced. However, since the thin wall portion 8 is provided at the bottom of the threaded cylinder portion 6, four portions are formed on the surface of the lid 2. Impurities such as dirt and moisture may enter the battery before the sensor is installed, adversely affecting battery performance, and impurities may accumulate in the threaded tube 5 when the sensor is installed. There were many problems in terms of reliability, such as poor fitting.

Surface, specific gravity sensor, etc. can be easily installed. Since the sensor mounting part 4 has a flat surface and no unevenness, impurities such as dust and water do not accumulate, and the appearance is improved. Furthermore, a shallow groove is provided around the back side of the lid opening 9.
Fig. 6 shows a second embodiment of the present invention, in which a recess 11 is provided on the surface and periphery of the lid 2 corresponding to the threaded cylinder portion 5 provided on the lid. According to this structure, when attaching a liquid level sensor, a specific gravity sensor, etc., the lid opening 10 can be easily removed by simply applying the lid opening 10 in the direction of the arrow a. It can be opened to reduce the amount of dirt, water, etc. that accumulates. Furthermore, the lid sealing sound 5
Since the wall thickness around the opening 10 is made thinner to accommodate the provision of the recessed part 11, there is no possibility that the opening will be caused by a large amount of deformation force when the opening is opened.
