The utility model provides a sensor support and a wheel hub unit bearing with the sensor support, wherein the flatness of circumferences of a sensor insertion portion and a Carre nut installing hole portion is guaranteed, and simultaneously, splash is prevented from reaching a sealing portion, the sensor and the Carre nut. The bottom of the sensor support (20) comprises a step portion (26) which is substantially extended lineally. The step portion (26) is designed as a boundary to form a concave portion (22) with a sensor holding portion and a convex portion (23) which is arranged at the rotation axis direction of an inner ring portion and is farther from the center of the wheel hub unit bearing then the concave portion (22). In the ring portion (21) supporting the convex portion (23), a water outlet portion (25) which passes through one part of the ring portion (21) radially is formed at the position father from the center of the wheel hub unit bearing then the concave portion (22). |
