<p><P>PROBLEM TO BE SOLVED: To provide a sensor-equipped bearing apparatus for a wheel capable of miniaturization. <P>SOLUTION: The sensor-equipped bearing apparatus for wheel is equipped with a fixed side outside member 1 formed with two rows of track surfaces 3 on an inner circumference, a rotating side inside member 2 having two inner rings 9A, 9B formed with track surfaces 4 facing each track surface 3, and two rows of rolling elements 5 interposed between the opposing track surfaces 3, 4. A pulser ring 20 is fit on one inner ring 9A of two inner rings 9A, 9B between the two rows of rolling elements 5, 5. A sensor 21 facing the pulser ring 20 and detecting rotation of the inside member 2 by targeting on the pulser ring 20 is attached to the outside member 1. The pulser ring 20 is cross-sectionally L-shaped comprising a fitting part 20a fitting on the one inner ring 9A of the two inner rings 9A, 9B, and a detection part 20b crossing the two rows of inner rings 9A, 9B and extending in an axial direction from an outer circumference end of the fitting part 20a to be detected by the sensor 21. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
