Abstract: The washing machine includes a tub containing wash water, a drum, a lifter, and a partition. The drum rotates inside the tub and has at least one inlet to introduce wash water contained in the tub. The lifter forms a chamber holding wash water introduced through the inlet together with the drum and discharges wash water into the drum through a plurality of discharge holes arranged from a front side to a rear side inside the chamber during the rotation of the drum. The partition divides the chamber into a front chamber and a rear chamber along a longitudinal direction of the drum and forms an angle inclined with respect to a circumference of the drum.
