Abstract

PURPOSE:To accurately detect a rotary speed and to perform the cost down by separately providing a number of holes in the circumferential direction in a plate-shaped magnetic material annular member while coating it with a synthetic resin made protecting member and providing a sensor rotor, comprising the plate-shaped magnetic material annular member and the synthetic resin made protecting member, in a rotatable ring. CONSTITUTION:A sensor rotor 40, constituted of an annular member 44 consisting of magnetic material and a synthetic resin made protecting member 46 enveloping this annular member 44, is fitted to be fixed to an outer ring 20 comprising a cylindrical part 22 and a flange part 24. This annular member 44 separately provides a number of rectangular holes 48 in the circumferential direction, and a sensor 50 is arranged adjacent to the peripheral surface of the sensor rotor 40. Accordingly, enabling the annular member 44 to relax its machining accuracy, preventing a rust and accurately detecting a rotary speed, the cost of manufacture can be reduced.
