# Electrolytic corrosion prevention member for rolling bearing and electrolytic corrosion prevention rolling bearing unit

## Abstract

An electrolytic corrosion prevention member for a rolling bearing, the electrolytic corrosion prevention member being mounted on a rolling bearing unit including the rolling bearing in which one bearing ring is a fixed ring and the other bearing ring is a rotating ring in order to prevent electrolytic corrosion of the rolling bearing, the electrolytic corrosion prevention member includes: a spring plate including an annular portion and a plurality of elastic portions that extend continuously from the annular portion in a radial shape and being formed of a thin plate of a conductive material; and a soft conductive member mounted on a surface of the elastic portion that faces the rotating ring. The soft conductive member is capable of abutting against a side surface of the rotating ring.
