Abstract
A rolling bearing unit for sensing rotational speed has a synthetic resin connector to which a plug is connected to output a signal from a senser, and a metal cover lot supporting and protecting the connector.
Claims6
A rolling bearing unit for sensing rotational speed comprising:
- a rotating ring,
- a stationary ring,
- a plurality of rolling bodies provided between the rotating ring and the stationary ring,
- a pulser ring mounted to the rotating ring,
- a sensor mounted to the stationary ring so as to oppose the pulser ring to detect rotations of the rotating ring,
- a synthetic resin connector integrally connected to the sensor to output a signal from the sensor,
- a metal cover which supports the sensor and the synthetic resin connector, and
- a supplemental metal member for protecting the synthetic resin connector, said supplemental member being connected to the metal cover in a telescopic fitting relationship, said supplemental member extending from the metal cover to substantially enclose the synthetic resin connector.
