WASHING MACHINE

PROBLEM TO BE SOLVED: To provide a washing machine capable of efficiently feeding washing water spouted from a pump chamber to a circulation water pathway while preventing the washing water from veering. SOLUTION: A pulsator 40 enclosed by a casing 20 is rotatably disposed on the bottom face 12 of a washing tub 10. A moving side water stop groove 51, which is a circular groove, is formed on a lower end face 50c of a rear outer peripheral wall 50 set in the pulsator 40, and a cylindrical fixed side water stop wall 21 which projects upward, is formed along the inner circumference of the casing 20. When the groove 51 intrudes into the wall 21, a labyrinth 1 is formed. A flange 61 which projects outward, is formed at the upper end of a front outer peripheral wall 60 set in the pulsator 40, and a cylindrical moving side water stop wall 62, which projects downward, is formed along the outer circumference of the flange 61. A fixed side water stop groove 23, which is circularly dented downward, is formed along the inner circumference of the casing 20, and a labyrinth 2 is formed when the wall 62 intrudes into the groove 23.
