特徴とする磁気式ロータリエンコーダ。 a rotatable rotating body having a magnetization pattern arranged in a circumferential direction; a holding member mounted on a predetermined reference plane portion on the outside of the rotating body; A magnetic rotary encoder is provided with a magnetic sensor facing the rotor, and detects a change in the position of a magnetization pattern due to the rotational movement of the rotating body based on a change in the output of an electric signal from the magnetic sensor, wherein the holding member is made of a metal plate. A member has a pair of legs facing each other with a predetermined interval and having fractured surfaces perpendicular to each other, and a pair of legs that bridges between these legs and is bent in a stepped shape with respect to a plane containing one of the fractured surfaces. and a mounting leg formed near the other fracture surface of both leg pieces and bent at a position away from the fracture surface, and the magnetic sensor is in contact with the fracture surface on one side. The magnetic rotary encoder is characterized in that the holding member is bonded to the fixing piece in a state in which the holding member is in contact with the reference plane part, and the mounting leg part is screwed in a state in which the other side of the holding member is in contact with the reference plane part. .
