PROBLEM TO BE SOLVED: To provide a highly reliable and inexpensive bearing with a sensor capable of measuring the rotated condition of a rotary ring with high accuracy over a long period by constructing a sensor housing into a non-annular shape. SOLUTION: The bearing with the sensor comprises the rotary ring (an inner ring) 2 and a stationary ring (an outer ring) 4 arranged opposing each other in a relatively rotatable manner, and the sensor 20 for detecting the rotated condition of the rotary ring, the sensor having a detected object 22 to be rotated in a rotated condition being the same as that of the rotary ring, a detector 24 for detecting the rotated condition of the detected object, and the sensor housing 26 storing the detected object. The detected object is fixed to the rotary ring to be rotated together with the rotary ring, while the detector is fixed to the stationary ring in such a state as being stored in the sensor housing so as to be opposed to the detected object at a predetermined space. The sensor housing is constructed into a non-annular shape extending to cover part of a peripheral region of the end face of the bearing. COPYRIGHT: (C)2008,JPO&INPIT
