PROBLEM TO BE SOLVED: To change a design easily by forming a panel element, in which both ends are bent in an arcuate shape to the inside and which has small width, and a stringer, to which the panel element is fitted, of panel elements, in which both ends having large width are bent in the arcuate shape to the insides. SOLUTION: A panel element 1, in which both ends are bent in an arcuate shape to the inside and which has small width, and a stringer 3, to which the panel element 1 is fitted and which has a plurality of projecting sections 2 corresponding to the width of the panel element 1, are formed. Panel elements 4 having large width in size extending over two of the projecting sections 2 of the stringers 3 are installed, the panel elements 1 having small width are fitted to the projecting sections 2 of the stringers 3, and the panel elements 4 having large width are fitted extending over two or more of the projecting sections 2 of the stringers 3. Accordingly, the panel elements having mutually different width are fitted to the stringers, and a design can be changed variously. |
