PROBLEM TO BE SOLVED: To provide a sensor cover which prevents a pulser ring from being damaged by the sensor cover and has high positional accuracy, relative to the pulser ring or the like in an anti-friction bearing system which rotatably supports a wheel in a suspension system of an automobile and has a rotation detecting device for detecting the rotational speed and the rotational direction of the wheel. SOLUTION: In the anti-friction bearing system, an outer peripheral edge of a sensor body 38 of the sensor cover 37 is bent to the inner side of a bearing, while a conical portion 39a, as a fitting portion, is formed at a bent portion 39. A conical portion 40a as a fitted portion for the fitting portion to be fitted is formed at an inner circumferential surface 40 of an outer ring 31. A position, in the axial direction of the sensor cover 37 relative to the pulser ring 15, is set by fitting the two conical portions, thereby providing the anti-friction bearing system which has a sensor cover provided with high positional accuracy relative to the pulser ring or the like.
