Abstract
The present invention inhibits an inductance of each winding of a conveyance device from varying with position. The conveyance device for conveying a conveyance target object having a magnetic material includes a plurality of teeth 20a, 20b, and 20c formed by a magnetic material, a plurality of windings 30 wound around each of the teeth 20a, 20b, and 20c, a yoke 40 in a shape of a lattice formed by a magnetic material that is magnetically connected to the teeth 20a, 20b, and 20c in order to support the teeth 20a, 20b, and 20c, and an additional yoke 45 formed by a magnetic material that is magnetically connected to an outer end of the yoke 40.
