PROBLEM TO BE SOLVED: To provide a rolling bearing device with a sensor, capable of reducing the number of part items in a sensor as well as improving reliability by preventing a foreign matter from going through a drive shaft to invade a detection region.SOLUTION: A sealing device 8 includes a core metal 8a and a slinger 8b. The slinger comprises a fitting section 8b1 fitted into an inner ring 2b, a sliding section 8b2 extending from the fitting section, a folded section 8b3 folded from the sliding section, a cylindrical section 8b4 which extends from the folded section and is formed with a gap between itself and a drive shaft 5, a discal section 8b5 which extends from the cylindrical section and is formed with a labyrinth between itself and a knuckle 3. The core metal comprises a core metal discal section 8a1 arranged oppositely to the sliding section, a core metal cylindrical section 8a2 which extends from the core metal discal section and is arranged oppositely to the fitting section, a fixed section 8a3 which extends from the core metal discal section and to which the sensor 10 is fixed. A magnetic encoder 9 is formed into a tubular shape to be fixed to an outer periphery of the cylindrical section. |
