に設けたことを特徴とする回転センサー。 At least four magnets having alternating magnetic poles are arranged at equal intervals on the same circle concentric with the rotation axis in the shape of a rotating disk, have a shell part and a core part, and at least the shell part is placed in a magnetic field. The pick-up coil is wound around a magnetic wire whose shell part has a sufficiently larger holding force than the core part, and the magnetic wire is separated from the surface of the magnet and parallel to the rotating disk. , and its longitudinal direction coincides with the line connecting adjacent magnets at a predetermined rotational position of the rotating disk, and in this state, one magnet faces approximately the center of the magnetic wire, and the other magnet faces from the end of the magnetic wire. A rotation sensor characterized in that it is installed in a separate position.
