Abstract

A shaft grounding member for a rolling bearing, the shaft grounding 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, the shaft grounding member includes: a spring plate including an annular portion, a coupling portion extending continuously from the annular portion in a radial direction, and an elastic portion bending from the coupling portion in an axial direction of the rotating ring, the spring plate being made of a thin plate of a conductive material; and a soft conductive member mounted on a surface of the elastic portion that faces a rotating member to which the rotating ring is fitted. The soft conductive member is capable of abutting against at least a part of a peripheral surface of the rotating member.
