PROBLEM TO BE SOLVED: To reliably and stiffly connect paper pipes and joints which are bent into L shape and to provide a chair using this connection structure. SOLUTION: Anterior legs 1, hind legs 2, floor contact pipes 9 are formed of paper pipes. Diagonal ends 13 are formed by cutting their ends diagonally. Each of joints 11 which has insertion parts 10 and is bent into L shape is provided with locking protrusions 12 in its bent part. The anterior legs 1, the hind legs 2 and the floor contact pipes 9 are put in the insertion parts 10 of the joints 11 respectively. The diagonal ends 13 are inserted between the locking protrusion 12 and the interior of the insertion part 10 and are fixed. COPYRIGHT: (C)2011,JPO&INPIT
