ダ。 A rotatable drum having a magnetization pattern formed in the circumferential direction, and a magnetic sensor disposed outside the drum to face each other via a holding member, the position of the magnetization pattern changing due to rotational movement of the drum. In a magnetic rotary encoder that detects based on a change in the output of an electric signal from the magnetic sensor, a sensor mounting surface for holding the magnetic sensor on the holding member formed by pressing a flat metal plate; A pair of leg pieces bent at both ends of the sensor mounting surface and having a mounting reference surface at the lower end, and a fixing mounting leg portion bent at a position above the mounting reference surface on these leg pieces, The magnetic field is characterized in that the surface is constituted by a fractured surface when a flat metal plate is punched out, and the sensor mounting surface and the leg piece are continuous at a bent part perpendicular to a plane including a mounting reference surface. type rotary encoder.
