機構。 A thrust bearing is installed between a rotating shaft inserted into a crank chamber to which power is transmitted via an electromagnetic clutch, a non-magnetic movable member connected to the rotating shaft, and a fixed member facing the movable member. In a compressor having a movable side thrust race interposed between a thrust bearing and a movable member,
It is made of a magnetic material and is formed to cover the thrust bearing side end surface of the movable member and the outer peripheral end of the movable member, and the part that covers the outer peripheral end of the movable member is the detected part and forms a crank chamber. A rotation in a compressor characterized in that an electromagnetic sensor with a built-in magnet is provided in a cylindrical casing facing the rotation locus of a detected part, and the rotation speed of a movable member is detected by the electromagnetic sensor. Number detection mechanism.
