PROBLEM TO BE SOLVED: To prevent dust from staying so as to make ease cleaning by bringing a roundness forming piece for a corner that is constituted of right angle abutting parts to be fitted to the corner and a curved surface having a sharp end interposed between both the abutting parts. SOLUTION: This piece comprises right angle abutting parts 2 to be fitted to a corner and a curved surface 3 with a sharp end interposed both the parts 2. In the case of a simple right angle corner, the parts 2 of the piece 1 is brought into contact therewith, and thus the crossing part at right angles is made round. In the case of a corner with a right angle edge, the piece is used that comprises a back abutting part 4 on the top angle of the right angle edge and the right angle abutting parts 2 on both sides thereof and the curved surface 3 with a sharp end. With the use of this piece 1 applied on orthogonal crossing parts of a corner in a room, it is eliminated to prevent dust from staying thereat for making easy cleaning.
