Dryer

A laundry machine, comprising:

• a main body having an inner space formed therein;
• a support body arranged in the main body so as to form a frame of the main body;
• a flexible drum having a front opening and a rear opening respectively formed at open front and rear faces thereof, rotatably arranged in the main body so as to have a non-circular cross-section;
• and
• rotation guides arranged between the main body and the flexible drum to guide rotation of the flexible drum, wherein the flexible drum is configured such that a first distance from a center of rotation of an inscribed circle contacting an inner circumferential surface of the flexible drum to at least one random point on the inner circumferential surface of the flexible drum is greater than a second distance from the center of rotation of the inscribed circle to another point on the inscribed circle,
• wherein each rotation guide includes a hooking space into which the front end or the rear end of the flexible drum is received and secured.
