Disclosed is a bearing assembly with a sensor, in which a sensor holder that is formed of a synthetic resin and is the annular member having ends is supported on an outer race using a circumferential groove of the outer race of a rolling bearing, and the sensor holder is adapted to be strongly fixed in position by a spring member having circumferential half-split elastic recovery portions. Because spring forces by which the sensor holder is strongly fixed in position as described above can be increased, the sensor holder can be more strongly fixed in position. A spring member (15) is a formed-wire spring formed of a square sectional wire, which includes a main portion (16) fitted in an annular groove (14) of a sensor holder (7), and opposite end portions (17) that circumferentially protrude from the annular groove (14) and are located inside an open recess (18) of the sensor holder (7). The opposite end portions (17) of the spring member (15) overlap in an axial direction when the main portion (16) is fitted in the annular groove (14), and are portions that abut and are deflected when one of the end portions (17) is shifted to remove the overlapping. The forces (F) caused by elastic recovery of the deflected end portions (17) increase the force of the main portion (16) pushing the sensor holder (7) in a radially outward direction. As a result, the spring forces by which the sensor holder (7) is strongly fixed in position are increased. |
