Claims

[Scope of utility model registration request]

(1) An ebonite lid with a threaded part on the inside and a recess with a through hole at the bottom, and a lead alloy bushing with multiple disc-shaped uneven parts on the outer circumferential surface, are made of synthetic resin. An adapter is formed by inserting it into the lid and screwed into a threaded part on the inner surface of the recess of the lid, and a lead alloy pole post passes through the center of the lead alloy bushing, and the lead alloy bushing and the lead A lead-acid battery is liquid-tightly fixed to an alloy pole post by welding, and one of the disc-shaped protrusions located between the upper and lower stages of the disc-shaped uneven parts of the lead alloy bushing. 1. A lead-acid battery characterized by having one or more notches in the section.

(2) The lead-acid battery according to claim 1, in which the notch provided in the disc-shaped convex portion is shaped like a half-moon or a U-shape that goes into the inside of the bushing.
