PURPOSE: A coupling apparatus of a power transmission shaft using a permanent magnet is provided to stably transfer power, extend life time, and accurately transfer power by maximizing magnetic flux using isotropy. CONSTITUTION: A coupling apparatus of a power shaft using a permanent magnet comprises a shaft(10), a power transfer shaft(10a), attachment disks(11,11a), a permanent magnet pieces(12,12a), a separation cylinder(20), and a separation plate(21). The separation plate(21) is integrated with the separation cylinder(20). After welding the shaft(10) to the attachment disk(11), the permanent magnet piece(12) that is formed by cones is allocated at one side of the separation plate(21). The cones of the magnet piece(12) are attached to each other to alter NS poles. After welding the power transfer shaft(10a) to the attachment disk(11a), the permanent magnet piece(12a) that is formed by cones is allocated at the other side of the separation plate(21). The cones of the magnet piece(12a) are attached to each other to alter NS poles.
