a casing;
a washing tub rotatably disposed in the casing, the washing tub comprising:
a drum having an elongated cylindrical shape, the drum having an opening defined at a front side of the drum and configured to receive laundry, and
a rear cover coupled to a rear end of the drum;
a motor configured to rotate the washing tub; and
a plurality of lifters where each lifter protrudes from an inner circumferential surface of the drum and is configured to lift the laundry from the inner circumferential surface of the drum based on rotation of the drum, the plurality of lifters extending along a longitudinal direction of the drum and being spaced apart from each other in a circumferential direction of the drum,
wherein the plurality of lifters include:
a front lifter that is disposed closer to the opening than to the rear cover, and
a rear lifter that is disposed closer to the rear cover than to the opening, the rear lifter being disposed rearward of the front lifter,
wherein a longitudinal center line of the front lifter and a longitudinal center line of the rear lifter are spaced apart from each other in the circumferential direction of the drum, and
wherein at least a portion of the front lifter overlaps with at least a portion of the rear lifter along the longitudinal direction of the drum such that the front lifter and the rear lifter at least partially overlap each other when viewed from the front side of the drum in a direction of a rotation axis of the drum.
