PROBLEM TO BE SOLVED: To provide a highly reliable bearing with a sensor, wherein an electric wire connected to a sensor portion is less broken. SOLUTION: The bearing 1 with the sensor comprises rolling elements 13, 14 arranged between an outer ring 12 and an inner ring 11. A groove 112 is formed in an inner diameter portion of the inner ring 11, and a groove 331 is formed in the outer peripheral face of a cylinder portion 33. A pin member 36 is fitted into the grooves 112, 331 to prevent the rotation of the inner ring 11 with the rotation of the outer ring 12. Thus, there is no torsion in a cable 70 which is connected to the sensor portion 22 mounted on an external seal 18 of the inner ring 11, resulting in no breakage. COPYRIGHT: (C)2006,JPO&NCIPI
