PURPOSE: To improve usability and to enable compact housing of undressed washing by a method wherein an opening and closing door which opens and closes independently is provided on either side and a bottom piece for receiving a divestment bascket is provided connected with the doors on both sides.

CONSTITUTION: A room partitioning housing box 1 is arranged so that a user can easily put in and take out undressed clothes at a position a little upward from a floor surface. Opening and closing doors 3 and 4 are provided opposing to each other, so that the user can open and close from both front and back sides of a divestment wagon 2 of the room partitioning housing box 1, that is, from either side of adjacent rooms thus partitioned by the box 1. An area of bottom pieces 31 and 41 engaged with each other between thus opposing two opening and closing doors 3 and 4 is designed to receive and support a divestment bascket 5 having a necessary largeness. When the divestment wagon 2 is opened from one room side by opening one of the opening and closing doors 3 and 4, the connected bottom piece 31 or 41 inclines and the divestment bascket 5 also inclines and comes out toward the user. Thus the user can easily put and take underessed clothes in and cut of the divestment wagon 2.
