摘要： A rotor to be used in combination with a wheel speed sensor forming part of an anti-lock brake system. The rotor comprises an annular axial central section formed of a magnetic material. First and second annular axial end sections are coaxial and integral with the central section. The first and second annular axial end sections are formed of the magnetic material and arranged such that the annular axial central section is located between the first and second annular axial end sections. A plurality of holes are formed in the annular axial central section. The holes are arranged at equal intervals in the peripheral direction of the annular axial central section. A plurality of first and second depressions are respectively formed in the first and second axial end sections. A pair of the first and each second depressions are respectively located opposite to each other and connected with each hole.

摘要： A rotor for an ABS wheel speed sensor which is capable of improving the yield of a material and a work effectiveness at assembly. The rotor 1 includes a ring-like rotor body 3 having a number of holes 2 arranged successively at an equal pitch, and an inner ring 4 having a C-shaped cross section and having, at at least one of its axial end portions, a flange section 6 bent and protruding outwardly. The inner ring is fitted in the interior of the rotor body 3. For coupling the inner ring 4 into the rotor body 3, the inner ring 4 is elastically deformed in diameter-reducing directions. In addition, the inner circumferential surface of the inner ring 4 is fitted onto a mating rotary shaft from the flange section side under pressure.
