PURPOSE: A pulsator having rotation balls is provided to obtain stronger stirring force by attaching rotation ball fixing elements inserted with a plurality of rotation balls between rotation plate wings of a pulsator for increasing the friction between the clothing and the water, thereby effectively removing the dirt from the clothing. CONSTITUTION: In a pulsator(6) having a top surface formed with a plurality of rotation plate wings(6a) protruded upwardly, and a bottom surface formed with a plurality of protruded ribs, rotation balls(20) are inserted between the plurality of rotation plate wings, wherein the rotation balls are mounted on fixing elements coupled on the top surface of the pulsator by a plurality of coupling elements, and the fixing elements are formed with a plurality of ball insertion holes to be inserted by the rotation balls and holding shoulder parts(32) protruded from inner peripheral surfaces of the ball insertion holes for preventing deviation of the inserted rotation balls. |
