PROBLEM TO BE SOLVED: To provide a pulser ring 10 that is used for a rotation detector which detects the rotating state of a wheel, etc., of an automobile, can prevent the detection accuracy of the detector from declining by preventing the deterioration of the flatness of an elastic magnetic layer 21, and can smoothly perform single- pole magnetization with superior accumulative pitch accuracy. SOLUTION: This pulser ring 10 consists of a first member 11 composed of a fit section 13 fit to the outer peripheral surface of an outer ring 2 and a bent section 14 bent inwardly in the radial direction from the fit section 13 and having a fixed section 15 at its front end and a second member 12 composed of a fixed section 16 fixed to the fixing section 15 and a flange section 17 which is outwardly extended in the radial direction from the fixed section 16 and the end face 18 of which is faced to a magnetic sensor 20. The second member 12 is provided with the annular elastic magnetic layer 21 on the end face 18 of the flange section 17. |
