構成したことを特徴とする駆動装置。 The ends of three magnetic rods arranged in parallel at a predetermined interval are connected with a magnetic material to form a Japanese-shaped magnetic path, and permanent magnets are placed inside the magnetic rods on both sides to form lines of magnetic force perpendicular to the central magnetic path. A linear motion guide member is fixedly arranged so that the flow of water flows in, and has a track formed on the outside of the magnetic rods on both sides. The movable coil has orbits on both sides corresponding to the orbits on both sides of the linear motion guide member, and is wound around the central magnetic path of the linear motion guide member with a predetermined gap so as to be perpendicular to the lines of magnetic force. The movable table is fixed to the movable table, and the steel balls for supporting the rolling guide of the movable table are held by a retainer and are interposed in a sandwiched state with a predetermined preload between the linear motion guide member and the raceways on both sides of the movable table. A drive device characterized by comprising:
