A sensor-equipped wheel support bearing assembly capable of accurately detecting load without affected by hysteresis is provided. The assembly includes a vehicle body fitting flange having bolt holes at respective circumferential portions in the form of projecting pieces. A sensor unit including a strain generating member having contact fixing segments to be fixed to the stationary member and a cutout portion, and a sensor element for detecting strain in a periphery of the cutout portion is provided with the contact fixing segments at positions of the same size in an axial direction relative to the outer diametric surface of the stationary member. The contact fixing segments are spaced each other an angle about an axis of the stationary member, and the angle between the contact fixing segments at respective end portions of the sensor unit is smaller than half the angle between the projecting pieces. |
