Provided is a drum washing machine (1) capable of preventing washings from generating cloth damage while detecting load quantity. The drum washing machine (1) includes: an outer tank (20), configured in a shell (10); a drum (22), configured in the outer tank (20) and capable of rotating by using a horizontal shaft or an inclination shaft inclining relative to a horizontal direction as a center; a rotating body (24), configured at a rear part of the drum (22) and having protruding parts (24a) in contact with washings on a surface of the rotating body (24); a driving part (30), capable of operating in a first drying form and a second driving form, wherein the first driving form refers to a driving form which enables the drum (22) and the rotating body (24) to rotate at different rotating speeds, and the second driving form refers to a driving form which enables the drum (22) and the rotating body (24) to rotate integrally at the same rotating speed; and a control part (801). Herein, the control part (801) detects the load quantity of the washings in the drum (22), and enables the driving part (30) to operate in a uniaxial driving form while detecting the load quantity (S13 and S14).
