Claims

[Scope of utility model registration request]

In a magnetic encoder that has a magnetized magnetic drum that rotates integrally with a rotating shaft and a magnetic sensor that detects changes in magnetic flux from the magnetic drum, the sensor mounting seat has the magnetic sensor adhesively fixed to one surface, and one end a first mounting seat having one through hole, a convex shape, a central protrusion on one of the convex surfaces having a threaded portion that fits into the through hole, and a screw portion that is perpendicular to the convex surface; It consists of a second mounting seat with holes for screws on each of the two sides sandwiching the central protrusion,
The first mounting seat is fixed between the second mounting seat, the latter's screw, and the former's through hole with a nut, etc., and the second mounting seat supports the rotating shaft via the bearing in the screw hole. A magnetic encoder characterized by being screwed into the housing.
