Disclosed is a drum washing machine aiming for simplified manufacture of a planetary gear mechanism in the case where a structure reducing rotational speed of a driving electric motor via the planetary gear mechanism and then transferring to the drum is used. The drum washing machine of the present invention reduces the rotational speed of the driving electric motor via the planetary gear mechanism and transfers same to the drum, thereby enabling the drum and a rotator with a protruding part to rotate at mutually different rotational speeds. The planetary gear mechanism comprises: a sun gear, an inner gear, a plurality of planetary gears (430) and a planetary gear frame (440). The planetary gear frame (440) has: a rear planetary frame (442) and a front planetary frame (441), which clamp the plurality of planetary gears (430) from two sides; and a fulcrum shaft (443) which is erected between the front and rear planetary frames and is able to be mounted with the planetary gears (430) in a rotatable manner. A base end part of the fulcrum shaft (443) is fixed on the rear planetary frame (442), before the fulcrum shaft (443) is mounted with the planetary gears (430). In addition, the front planetary frame (441) is fixed on a front end part (443a) of the fulcrum shaft (443) mounted with the planetary gears (430). |
