The planetary gear mechanism includes an input axis, a planetary gear outer periphery portion fixed to the outer rotary axis, and a planetary gears coupled to the inner rotary axis and engaging with the outer periphery of the input axis and the inner surface of the planetary gear outer periphery portion. The washing machine further includes an electric motor and power transmission mechanism, and a brake arranged near the planetary gear outer periphery portion, releasing the planetary gear outer periphery portion at least during washing, and clamping the planetary gear outer periphery portion during dehydration. Preferably, the agitator has a liquid passing hole formed at the bottom. More preferably, the electric washing machine further includes convex portions provided on the bottom surface of the container type agitator.
