Abstract:
A sensor unit includes a collector and a sensor housing. The collector faces a stator guiding a magnetic flux, with a void between the collector and the stator, and collectively attracts the magnetic flux guided by the stator. The sensor housing has a wall covering outside of the collector, and holds the collector. A clearance is formed between an opposite surface of the collector to a surface thereof facing the stator, and the wall of the sensor housing.
