PROBLEM TO BE SOLVED: To attain a reduction in size, avoidance of complicated wiring around a bearing, and improvement in sealing property of the bearing while retaining rotating speed detecting function, and to dispense with the connecting work of a generator stator to a transmitting means to reduce the manpower of assembling. SOLUTION: This bearing device comprises an outer member 1 having double row rolling faces 6 and 7 on the inside surface, an inner member 2 having rolling faces 8 and 9 opposed to the rolling faces 6 and 7, and a double row rolling body 3. The outer member 1 integrally has a body mounting flange 1a on the circumference, and the inner member 2 has a wheel mounting flange 2a at one end. This device further comprises a generator 4 formed of the stator 17 mounted on the bore part of the outer member 1 and a rotor 18 mounted on the inner member 2 and used also as a rotation sensor; the transmitting means 5 for wirelessly transmitting the electric signal from the generator provided on the outer surface of the outer member 1; and a connector 30 for connecting the transmitting means 5 to the stator 17 in a single operation. |
