PURPOSE:To obtain a magnetic levitation carrying device which can perform contactless and slideless guidance of a carrying vehicle through a branch section and a linear section by carrying out branch control at the branch section through selection of right and left magnetic forces. CONSTITUTION:Under normal running, a carrying vehicle 10 is controlled by electromagnets 12, 12' such that a gap with respect to the inner wall 16' of a rail 15 is constant. When the carrying vehicle 10 is required to run straight, a rail mark sensor 13 detects a rail mark 17a and controls such that a gap with respect to the outside inner wall 16 is constant. Consequently, the carrying vehicle 10 enters branch side. With such arrangement, rails need not be cut thus simplifying the shape of the rail. Furthermore, since the right and left gaps are controlled actively when the carrying vehicle runs or enters a branch, stability is ensured during high speed straight running.
