A pulsator for a washing machine mounted in a washing tub and for generating a waterflow in washing water in the washing tub by a rotation according to a rotation of a shaft housing, comprising:

• a base plate fixed to the shaft housing to be rotated according to a rotation of the shaft housing;
• a plurality of plate-shaped wings radially fixed to the upper surface of the base plate so as to be rotated according to the rotation of the base plate, and for forming a concentric waterflow in the washing water, each of the plurality of plate-shaped wings having a multi-stepped edge;
• a plurality of cover plates fixed on the multi-stepped edges of the plurality of plate-shaped wings, each being a disc-shaped plate having a hole in the center portion;
• a plurality of protrusions radially and in a certain length formed on the upper surface of each of the plurality of cover plates, and for generating a waterflow of the washing water vertically oriented toward the top of the washing tub by being rotated according to the rotation of the base plate.
