PURPOSE: A drain device of a washing machine is provided to realize the use of a D/C motor of low power consumption for indirectly rotating a rotation plate of a larger radius while rotating an impeller with stronger power. CONSTITUTION: A drain device of a washing machine includes a motor case(130), a motor(100) with a rotation shaft(102), a magnet rotator(110) fixed to the rotation shaft to rotate and having branched N and S poles by a predetermined section, a driven magnet(120) branched into polarities corresponding to the respective polarities on the outer periphery of the rotator, a rotation plate(122), where the driven magnet is fixed, having a first central shaft(124) penetrating the motor case, a pumping case(150) coupled with the motor case by a sealing element(160) and having an inlet(152) and an outlet(154), and an impeller(140) axially supported to the pumping case to be incorporated in the pumping case and formed with a second central shaft(142) to be coupled with the first central shaft. |
