Abstract
An encodera characteristic of which is changed alternately at an equal interval in a circumferential direction is supported/fixed onto a hubconcentrically with the hub. A sensing portion of a sensorsupported on the outer ringis positioned in close vicinity to a sensed surface of the encoderto face thereto. Width dimensions of first and second sensed portions provided onto the sensed surface are changed continuously in a direction along which a to-be-sensed load is applied. Since a pattern according to which an output signal of the sensoris changed is changed pursuant to a change of the load, the load is derived by observing this pattern. The output signal is also utilized to sense a rotation speed of the hubin ABS or TCS control.
