A drum washing machine capable of sufficiently obtaining a washing effect brought by a rotating body is provided. The drum washing machine (1) includes: an outer tank (20) arranged in a housing (10); a drum (22), which is arranged in the outer tank (20) and capable of rotating about a horizontal shaft H; a rotating body (24), which is arranged at a rear part of the drum (22), and a surface of the rotating body (24) being provided with a projection (24a) for contacting washings; and a driving part (30), configured to drive the drum (22) and the rotating body (24) to coaxially rotate at different rotating speeds. The drum has a baffle (23) arranged on an inner circumferential surface of the drum (22), which is used as a moving unit configured to move the washings in the drum (22) towards the rotating body (24). The baffle (23) has gathering surfaces (23R, 23L) for gathering the washings through a rotation of the drum (22). The gathering surfaces are inclined so that the side of the rotating body (24) is lagged
