PROBLEM TO BE SOLVED: To enable dielectric or conductive radio wave absorbers to be securely and easily attached to the inner wall and ceiling board of a radio wave dark room by a small number of people in a short time without providing a special prolonged fixed scaffold or a stationary stand at a working site. SOLUTION: When a radio wave dark room is constructed, auxiliary attachments are fixed direct or together with ferrite tile panels at regular intervals with machine screws on the inner walls and ceiling board of the radio wave dark room which is electromagnetically shielded by metal plates or the like. Side boards, which are joined to two or more sides of four sides of the base of the auxiliary attachment by a linking means that makes a relative position changeable, are attached to or made to cover the lower end face of the nearly pyramidal or wedge-shaped radio wave absorber so that the radio wave absorber is fixed to the auxiliary attachment with securing pins. The auxiliary attachment is kept in a flat shape in transit and easily assembled at a working site. COPYRIGHT: (C)2005,JPO&NCIPI
