PROBLEM TO BE SOLVED: To provide a comfortable chair by preventing a longitudinal deformation of a seat part and a back part of a portable folding chair. SOLUTION: First open passages (150 and 151) are formed on both widthwise ends of the seat part (110) and the back part (120) so as to extend longitudinally to connect the back part (120), a connecting part (130), and (110). Rigid bars (160 and 161) are inserted into the first open passages (150 and 151). COPYRIGHT: (C)2007,JPO&INPIT
