The present invention relates to a magnetic gear and, more specifically, to a salient pole-type magnetic gear, which : replaces a magnet of any one pole of magnet dipoles of the inner rotor and/or the outer rotor with a salient pole having an iron core stacked thereon such that a rare-earth permanent magnet can be used less; and improves the form of a pole piece so as to concentrate magnetic flux on a pore such that transfer torque can be improved and a reduction in torque ripple can be implemented.
