    Abstract: The present disclosure relates to a washing machine configured to rotate a cylindrical drum formed by processing a metal sheet about a horizontal axis. The drum includes a lifter, formed by processing the metal sheet, respectively provided at a plurality of points spaced along a circumferential direction, when viewed from a front side. The lifter includes a front lifter which is formed by protruding the metal sheet into the drum, and pressurized to be extended in a longitudinal direction of the drum, and a rear lifter disposed in a rear side of the front lifter. The rear lifter is disposed to form a certain phase angle with respect to the front lifter.

    Abstract: A washing machine includes a casing, a tub, a drum, a pump, a gasket that is arranged between a case opening and a tub opening and that includes first nozzles and second nozzles, and a water pipe assembly that includes: first nozzle ports affixed to the first nozzles, second nozzle ports affixed to the second nozzles, a first conduit, and a second conduit. The gasket further includes port insertion pipes into which the first and second nozzle ports are inserted. Each of the first and second nozzle ports includes at least one press-fit protrusion that is formed on an outer circumferential surface of the nozzle supply port and that is configured to, in a state in which the nozzle supply port is inserted into a corresponding port insertion pipe, maintain contact with an inner circumferential surface of the port insertion pipe.
