PROBLEM TO BE SOLVED: To provide a washing machine capable of washing the inner surface of a water containing tank. SOLUTION: A plurality of blades 41 is arranged on the lower surface of a pulsator 40, and an annular plate 42 is placed at the lower ends of the blades 41. The blades and the annular plate form substantially truncated pyramid-like acceleration flow paths 43. A circulation water path 50 is vertically formed on the inner surface of a washing tank 30, and a plurality of ejection holes 70 is formed in the area of the circulation water path 50 of a washing circular tube section 33. Except the outlet 52 of the circulation water path 50, the periphery of the pulsator 40 is surrounded by a casing 60, so that washing water discharged by rotation of the pulsator 40 flows into the circulation water path 50 and is ejected toward the water containing tank 20 from the ejection holes 70 in the washing circular tube section 33.
