Claims

[Scope of utility model registration request]

A magnetic drum having a magnetization pattern, a magnetic sensor having a magnetoresistive element on a glass substrate,
In a magnetic rotary encoder comprising a magnetic drum and a frame holding a magnetic sensor, the magnetic sensor detects a change in the position of the magnetization pattern as the magnetic drum rotates,
A holding hole with one side as a reference surface and a shaft hole facing the reference surface are each drilled in the same plane of the frame, a bearing for supporting the magnetic drum is press-fitted into the shaft hole, and the holding hole is press-fitted into the shaft hole to support the magnetic drum. A magnetic rotary encoder characterized in that the glass substrate is adhesively fixed to the hole with its magnetoresistive element forming surface in contact with the reference surface.
