ROLLING BEARING UNIT WITH ROTATING SPEED DETECTING DEVICE

摘要

PROBLEM TO BE SOLVED: To materialize a structure for securing reliability and durability of a cover, and capable of preventing this cover from being pushed into the encoder side. SOLUTION: A sensor holding bracket 25 is fitted around and fixed to an inner end part in the axial direction of an outer ring 4 in a state of covering an outer end opening part of the outer ring 4 covered with the cover 18. A recessed part 31 recessed in the axial direction is formed in a part in the circumferential direction in an outer diameter near part of a holding plate part 27 for constituting this sensor holding bracket 25, An inner surface of this recessed part 31 is allowed to abut on an inner end surface in the axial direction of the outer ring 4, to thereby regulate a position in the axial direction of the sensor holding bracket 25 to this outer ring 4.
