Abstract: The present application relates to a clothing processing apparatus comprising: a cabinet provided with a first housing and a second housing which provide an accommodation space; an outlet passing through the upper surface of the cabinet and communicating with the second housing; a first support part that can rotate from one surface of the cabinet toward the upper surface of the cabinet, and provides a space in which clothing is supported; a processing part which can be withdrawn from the first housing and provided so as to supply at least one of heat or moisture to the clothing; a body which can be withdrawn from the second housing via the outlet; and a second support part which is provided in the body and located above the first support part, provides a space in which the clothing is supported, and has a smaller area than the first support part. The second support part includes: a first board which is fixed to the body so as to be capable of rotating from the body toward the upper surface of the first support part; and a second board which is rotatably fixed to the first board so as to be capable of rotating on a plane parallel to the upper surface of the first support part, and which provides a space in which the clothing is supported.
