Abstract:
A body part of a rotation detecting sensor of a rotation number detector which is provided on a bearing apparatus for an axle has a large diameter part formed in its upper part and a small diameter part formed in its lower part, and at the same time, a sensor fitting hole part which is formed in an outer ring of a bearing part and into which the body part of the rotation detecting sensor is inserted is so formed that an radially outer part thereof has an inner diameter substantially equal to an outer diameter of the large diameter part of the body part, and a lower part thereof has an inner diameter slightly larger than an outer diameter of the small diameter part of the body part.
