<p>PROBLEM TO BE SOLVED: To provide a rolling bearing with a sensor capable of highly accurately positioning a magnetic sensitive sensor, and to provide an automobile, a railway vehicle, iron-making facility, and a machine tool.SOLUTION: A rolling bearing 1 with a sensor includes: a rotation side wheel 2; a fixed side wheel 3; a rolling element 4 interposed between the rotation side wheel 2 and the fixed side wheel 3; a ring magnet 11; and a magnetic sensitive sensor 15 opposed to the ring magnet 11 in an axial direction. A locking concave groove 7 is formed on a fixing part of a sensor housing 16 on the inside of an axial end face in the fixed side wheel 3 and a grip part 16d for grasping between the axial end face and the locking concave groove is formed on the fixing part to be fixed on the fixed side wheel 3 in the sensor housing 16. The grip part 16d includes at least a plurality of abutting pieces 16e projected in a radius direction of the fixed side wheel 2 so as to abut on the axial end face and a locking piece 16g having a locking part 16f allowed to be locked on the locking concave groove 7 while maintaining an abutting state of the abutting pieces 16e on the axial end face.</p> |
