Abstract
Official abstract text for this publication.
A nut is used with being fixed to a sensor cap. The sensor cap is attached to an outer ring of a bearing in a wheel bearing device of an automobile. The sensor cap includes a sensor holder for holding a magnetic sensor. The nut is made of steel, and has a screw portion in which a bolt is screwed to attach the magnetic sensor to the sensor cap. A surface of the nut is coated with a zinc-nickel alloy plating layer with a nickel eutectic ratio of 8 to 18%.
