MAGNETIC GEAR DEVICE

摘要

The present invention provides a magnetic gear device capable of improving the forces transmitted between a first magnet row and a magnetic body row and between a second magnet row and the magnetic body row. The magnetic gear device is equipped with a first magnet row in which a plurality of magnetic pole pairs are arranged at substantially equal intervals in a specific direction; a second magnet row which is opposed to the first magnet row and in which a plurality of magnetic pole pairs are arranged at substantially equal intervals in the specific direction at a pitch shorter (or longer) than that of the first magnet row; and a magnetic body row which is disposed between the first magnet row and the second magnet row and in which a plurality of magnetic bodies are arranged at substantially equal intervals in the specific direction, wherein a distance between the plurality of magnetic bodies and the second magnet row in the opposing direction is shorter (or longer) than a distance between the plurality of magnetic bodies and the first magnet row.
