Provided is 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 cylindrical first magnet row in which a plurality of magnetic pole pairs are arranged at substantially equal intervals in a circumferential direction; a cylindrical second magnet row which is arranged coaxially at an outer side of the first magnet row so as to be opposed to the first magnet row and in which a plurality of magnetic pole pairs are arranged at substantially equal intervals in the circumferential direction at a pitch shorter than that of the first magnet row; and a cylindrical magnetic body row which is disposed between the first magnet row and the second magnet row and in which a plurality of magnetic bodies 22 are arranged at substantially equal intervals along the circumferential direction, wherein a distance between the plurality of magnetic bodies 22 and the second magnet row is shorter than a distance between the plurality of magnetic bodies 22 and the first magnet row, and each magnetic body 22 is configured to be widened in the circumferential direction on the side of the first magnet row compared to the side of the second magnet row. |
