転数が検出される。Next, the function and effect of this embodiment will be described. When the wheel rotates, the hub inner ring 10 rotates by being allowed to rotate by the pair of angular contact bearings 16, 34 and 38; 18, 36 and 40. The nut member 50 rotates together with the hub inner ring 10, and the gear portion 54 thereof passes in front of the sensor 70.

とになる。The sensor 70 is covered with a cover 60 so as to be shielded from the outside world. Therefore, rainwater, muddy water, or the like does not splash on the sensor 70, and peripheral members do not interfere with this, so that there is no risk of the sensor 70 rusting or the position of the sensor 70 shifting. Therefore, the sensor 70 can detect the rotation speed of the wheel satisfactorily and intermittently.
