動装置。 In a rotation detection sensor, a magnetoelectric transducer is placed opposite the outer peripheral surface of a magnet that is magnetized with multiple poles in the circumferential direction and rotates together with the shaft, and detects rotation of the shaft by changes in magnetic flux across the magnetoelectric transducer. A rotation detection sensor characterized in that a braking yoke made of a ferromagnetic material is provided facing the outer peripheral surface of the magnet so that when the conversion element and one magnetic pole of the magnet are in opposing positions, it faces the other magnetic pole. Braking device.
