Summary:A rotor unit includes a plurality of rotating bodies arranged along a central axis. Each of the plurality of rotating bodies includes an annular rotor core surrounding the central axis, a plurality of magnets arranged in the circumferential direction around the rotor core, and a holder arranged to hold the magnets. Further, the holder includes a plurality of partitioning portions each axially extending between respective ones of the plurality of magnets. The axial dimension of the plurality of partitioning portions is longer than the axial dimension of the respective ones of the plurality of magnets which are held by the plurality of partitioning portions. Further, the plurality of rotating bodies is disposed in a state where the circumferential positions of the plurality of magnets are out of alignment.
