A washing machine comprising: a casing having an entry hole formed in a front surface of the casing; a tub provided in the casing to contain wash water, and having an entrance hole formed in the front surface of the tub; a drum rotatably provided in the tub; a gasket, wherein the gasket comprises a gasket body forming a passage connecting the entry hole and the entrance hole of the tub, and a plurality of nozzles spraying wash water into the drum, and wherein, the gasket body being bilaterally divided into a first area and a second area, the plurality of nozzles comprises a first nozzle and a second nozzle disposed in the first area sequentially in a bottom-to-top direction, and a third nozzle and a fourth nozzle disposed in the second area sequentially in the bottom-to-top direction; a pump configured to pump the wash water discharged from the tub; a circulation pipe for guiding the wash water discharged from the pump; and a distribution pipe for distributing the wash water guided through the circulation pipe to the first, second, third, and fourth nozzles, wherein the distribution pipe comprises: an inlet port connected to the circulation pipe; a first conduit part disposed in the first area on an outer circumferential surface of the gasket body to guide the wash water introduced through the inlet port; a first outlet port and a second outlet port arranged on the first conduit part sequentially in the bottom-to-top direction to supply the wash water, guided along the first conduit part, to the first and second nozzles (65a, 65b), wherein the first and second outlet ports (84a, 84b) extend in parallel from the first conduit part toward the outer circumferential surface of the gasket body; a second conduit part disposed in the second area on the outer circumferential surface of the gasket body to guide the wash water introduced through the inlet port; and a third outlet port and a fourth outlet port arranged on the second conduit part sequentially in the bottom-to-top direction to supply the wash water, guided along the second conduit part, to the third and fourth nozzles (65c, 65d), wherein the third and fourth outlet ports (84c, 84d) extend in parallel from the second conduit part toward the outer circumferential surface of the gasket body. a casing having an entry hole formed in a front surface of the casing;
