Claims

[Claims for Utility Model Registration] 1. A rotating drum fixed to the rotating shaft of a motor,
a sensor provided opposite to the rotating drum;
An encoder sensor positioning device comprising a sensor base that holds the sensor and a bracket for the motor that fixes the sensor base, wherein the bracket is provided with a spigot part that is concentric with the outer diameter of the rotating drum, and the sensor base 1. A sensor positioning device for an encoder, characterized in that an arc-shaped contact portion is provided on the outer periphery of the spigot portion, the contact portion being in close contact with the spigot portion. 2. The encoder sensor positioning device according to claim 1, wherein the rotating drum is composed of a magnetic drum, and the sensor is composed of a magnetic sensor. 3. The encoder sensor positioning device according to claim 1, wherein the rotating drum is constituted by a slit disk of an optical encoder, and the sensor is constituted by a photodetector having a fixed slit.
