Rolling bearing apparatus

摘要

An inner ring contact member (2) is mounted on a rotation shaft (10) to be disposed at a lower side of an inner ring (3) in a vertical direction such that a larger-diameter end of a conical outer peripheral surface (16) abuts against an axial end surface (11) of the inner ring (3). The conical outer peripheral surface (16) is formed such that the larger-diameter end of the conical outer peripheral surface (16) is disposed radially inwardly of a radially outward edge of the end surface (11) of the inner ring (3). A cage (6) is disposed between the inner ring (3) and an outer ring (4) in such a manner that a first annular portion (13) of the cage (6) close to the conical outer peripheral surface (16) is disposed so as to overlap with the end surface (11) of the inner ring (3) in the radial direction.
