Abstract
A sensor ring is coaxially mounted on a free end portion of a rotating element for detecting rotations of the rotating element. The free end portion defines an axially extending cylindrical surface and a radially extending stop surface for mounting of the sensor ring. The sensor ring has a cylindrical portion which defines a cylindrical center opening to be press fitted over the axially extending cylindrical surface of the free end portion of the rotating element. The sensor ring also has a flange portion which extends diagonally radially outward from one end periphery of the cylindrical portion such that the flange portion abuts on the stop surface of the free end portion of the rotating element when the sensor ring is completely mounted on the rotating element. The diagonally extending flange portion can avoid a connection curvature between the axial and radial surfaces of the free end portion of the rotating element during the press fitting operation.
