There is a concern that this gap (: electrolyte and other impurities may accumulate and corrode the metal sealing plate or reduce the degree of sealing of the battery). If an annular recess is formed in the lower part to absorb the deformation of the insulating packing during tightening, the peeling phenomenon of the rising part of the insulating packing can be prevented and the above-mentioned disadvantages can be eliminated, which is an additional effect.
