To efficiently transmit rotation.

Magnets M3 are arranged by alternating the north pole and the south pole on the surface of a movement board 23 which is moved by a drive 22. Rotation bodies 14, 15 supported by bearings 8A, 9A, 10A are arranged closely to the surface of the board 23. Magnets M1, M1 are arranged by alternating the north pole and the south pole on the periphery surfaces of the rotation bodies 14, 15 facing the surface of the movement board 23. A work W is connected to the rotation bodies 14, 15. When the movement board 23 is moved, the rotation bodies 14, 15 are rotated, without contact, by the interaction of the magnet M3 of the movement board 23 with the north pole and the south pole of the magnets M1, M1 of the rotation bodies 14, 15.
