摘要 |
A sensor holder has an encoder and a wheel speed sensor arranged opposite to the encoder, via a predetermined air gap. An annular fitting member is formed by pressing an anti-corrosive steel plate. A holding portion is formed of injection moldable synthetic resin and is integrally formed with the annular fitting member. The wheel speed sensor is embedded in the holding portion.
