A conveyor apparatus in which magnetic liquid is provided between a transfer track and a transfer object and a permanent magnet is fitted on the bottom of the transfer object to attract the magnetic liquid to move together with the transfer object thereby serving as a lubricant and permits the transfer object to move on the track afloat or buoyed-up by the magnetic liquid. An edge of a magnetic pole is shaped to have a loft angle in contact with the magnetic liquid to produce an upward component during its movement thereby increasing buoyancy and stability of the transfer object. Dust stir-up is precluded by virtue of the use of a magnetic liquid, as opposed to a conventional pressurized air support method.
