Provided is a drum washing machine, enabling a drum and a rotating body to rotate by a driving part, wherein the driving part includes: a driving motor; a first rotating shaft; a second rotating shaft; drum belt wheels; wing belt wheels; and a clutch mechanism part switching a driving form of the driving part between a biaxial driving form and a uniaxial driving form, wherein the biaxial driving form is a form that enables the drum and the rotating body to rotate at different rotating speeds through connecting the second rotating shaft and the wing belt wheels, and the uniaxial driving form is a form that enables the drum and the rotating body to rotate at a same rotating speed through connecting the second rotating shaft and the drum belt wheels.

Under the condition that the rotation speed of a first rotating shaft is higher than that of a second rotating shaft, supported portions go through right-handed helical flutes to perform an engaging operation. Under the condition that the rotation speed of the first rotating shaft is lower than that of the second rotating shaft, the supported portions go through left-handed helical flutes to perform the engaging operation. In a releasing operation, the supported portions go through the right-handed helical flutes to release a clutch mechanism under the condition that the rotation speed of the first rotating shaft is lower than that of the second rotating shaft, and the supported portions go through the left-handed helical flutes to release the clutch mechanism under the condition that the rotation speed of the first rotating shaft is higher than that of the second rotating shaft.
