PROBLEM TO BE SOLVED: To provide a bearing device for a wheel with a rotation speed detector which is improved in reliability, by not only improving workability for assembly but also inhibiting foreign matters from infiltrating the detector. SOLUTION: In the bearing device for the wheel with the rotation speed detector of internal wheel rotation type, a sensor holder 10 is provided with a corrosion-proof steel made cover 11 and a holder part 12 of synthetic resin made in which a rotation speed sensor 14 is embedded and a harness 21 for taking out the output of the same is connected. The cover 11 is formed into an annular shape with a cylindrical fitting part 11a to be fit to the end part of an external member 5, a flange part 11b extending internal direction, and a bottom part 11c extending internally, wherein a fixed part 13 having a notched part 22 on the external direction of the bottom part 11c; and since the holder part 12 is inserted into the notched part 22 and is connected to the fixed part 13, fixing operation of the harness is simplified, and the workability for assembly can be improved.
