Patent ID: 6994472

Claim:
A rolling bearing apparatus comprising: an inner ring member comprising a rotating ring having a raceway surface; an outer ring member arranged concentric with the inner ring member, said outer ring member comprising a fixed ring having a raceway surface in correspondence with the inner ring member; a rolling member interposed between the respective raceway surfaces of the inner ring member and the outer ring member; a seal apparatus for sealing a clearance between the inner ring member and the outer ring member; and a rotation detector for detecting a state of rotating the inner ring member, wherein the seal apparatus includes an outer ring side seal ring fixed to the outer ring and an inner ring side seal ring fixed to the inner ring member, and wherein the rotation detector includes a magnetic sensor molded by a resin-made external member to integrate therewith on an outer diameter side of a ring-like core metal of the outer ring side seal ring and a magnetic ring fixed to an inner face of a ring-like core metal of the inner ring side seal ring, said rotation detector detecting a rotational speed and a rotational direction of the inner ring member by the magnetic sensor detecting the magnetic ring.
