Abstract: A transfer apparatus includes a guide rails extending parallel with each other, a vehicle configured to be movable along the guide rails, and a contactless driving module mounted to the vehicle. The contactless driving module includes a pair of running rails extending parallel with the guide rails and comprising a plurality of first permanent magnets and a plurality of second permanent magnets arranged in a extending direction, respectively, a driving wheel disposed between the running rails to be spaced apart from the running rails and comprising a plurality of third permanent magnets arranged in a circumferential direction, and a driving unit for rotating the driving wheel. Particularly, at least one of the third permanent magnets is disposed between the first permanent magnets and the second permanent magnets.
