Abstract
In the rolling-bearing unit with rpm detecting device of this invention, there are first and two opposing sections where the sensor is faced to the tone wheel, and the magnetic resistance at these two opposing sections changes at the same time as the rotating ring rotates. These two opposing sections are located in series in the magnetic circuit which includes the stator.
