LEAD-ACID BATTERY TERMINAL MEMBER AND LEAD-ACID BATTERY

摘要

A lead-acid battery terminal member includes: a terminal portion which is arranged in a resin-made cover for closing a container; and a cylindrical bushing which is connected to the terminal portion through a conducting portion. The bushing is embedded in the cover; and has a plurality of annular projecting portions formed on an outer periphery thereof. Poles extending from an electrode group arranged in the container are inserted into and are welded to the bushing. Surface roughness of a surface of the annular projecting portion which faces a resin forming the cover in an opposed manner is lower than surface roughness of a surface of a portion other than the annular projecting portion.

1. A lead-acid battery terminal member comprising:
a terminal portion which is arranged in a resin-made cover for closing a container; and a cylindrical bushing which is connected to the terminal portion, is embedded in the cover, and has a plurality of annular projecting portions formed on an outer periphery thereof, and into which poles extending from an electrode group arranged in the container are inserted and to which the poles are welded, wherein surface roughness of at least a portion of the outer periphery of the bushing which faces a resin which forms the cover is lower than surface roughness of the terminal portion.
