Abstract
The sensor holder has an annular portion that holds the sensors. A holding ring that is securely fitted in an inner peripheral surface of a cylinder portion constituting a cover made of metal in terms of a large tight fit is embedded in an intermediate portion of this annular portion in the axial direction. A portion of a folded portion of the holding ring in the axial direction is set in a just center position between axial positions of sensing portions of both sensors. According to this configuration, the above problem is solved by preventing such a situation that the thermal expansion or the thermal contraction yields a phase difference between the output signals of both sensors.
