A pulser ring is fixed to a ring shaped core metal of the inner ring side seal ring. On an outer diameter side of the ring shaped core metal of the outer ring side seal ring, a magnetic sensor is molded with resin by an external member to be integrated therewith. A connector connected to the magnetic sensor is successively formed with the external member. A reinforcing member which reinforces the sensor side connector is provided on at least either of the external member or the sensor side connector.
