Abstract
A device includes: a first magnet array; a first magnet support body; a second magnet array; a second magnet support body; a gap drive mechanism for performing vertical drive of the magnet support bodies to change a gap; first, second connection beams connected to the magnet support bodies; a mechanism for connecting the connection beams to the gap drive mechanism; a cancellation spring mechanism for cancelling a suction force that acts between magnet arrays; and a spring interlocking mechanism for connecting the cancellation spring mechanism to the magnet support bodies. In the spring interlocking mechanism, first and second spring support frames that are connected to the first and second connection beams via a connecting portion, and a guide mechanism for guiding vertical movements of the first and second spring support frames are mounted, and the cancellation spring mechanism are mounted to both the first and second spring support frames.
