Claims

[Scope of utility model registration request]

In a magnetic encoder that has a magnetized magnetic drum that rotates together with the rotating shaft and a magnetic sensor that detects changes in magnetic flux from the magnetic drum, the sensor mounting seat has an insulator on one surface of the magnetic sensor. a first mounting seat fixed with adhesive between the two, and having a plurality of holes for screws on a protruding surface perpendicular to the sensor mounting surface; and a screw hole for mounting the first mounting seat on one surface; One cylindrical projection on a surface perpendicular to this, two projections whose one surface is the same plane as the surface from which the cylindrical projection comes out from two surfaces perpendicular to the above two surfaces, and each of these projections has an ellipse. It consists of a second mounting seat provided with a hole, the first mounting seat is screwed to the second mounting seat through the plurality of screw holes, and the second mounting seat is configured to shrink-fit the drum, etc. 1 provided on a protrusion provided on a part of the outer periphery of the housing that supports the rotating shaft fixed via a bearing.
The cylindrical protrusion of the second mounting seat is inserted into the two circular holes, and the screw hole provided on the same surface as the circular hole of the housing protrusion connects the oval hole of the second mounting seat with the screw. A magnetic encoder characterized by being fixed in place.
