The present disclosure reduces sound generated when a driving mode of a drum washing machine having a rotating body on a rear part of a drum is switched between a first mode and a second mode. The first mode is a driving mode in which the drum and the rotating body independently rotate, and the second mode is a driving mode in which the drum and the rotating body integrally rotate. A bearing-side cushioning member (540) is arranged on a clutch carrying plate (530) side. The bearing-side cushioning member (540) firstly touches an object side when a spline (611) of a clutch body (610) is engaged with a spline (534) of the clutch carrying plate (530), so as to reduce an impact force generated between the clutch body (610) and the clutch carrying plate (530).
