PROBLEM TO BE SOLVED: To provide a frame structure capable of securing assembling easiness and flexibility of the frame structure, while suppressing the number of parts and cost, by joining pipes with a simple constitution without requiring a lid member to close an opening of a pipe frame. SOLUTION: In this frame structure, a distal end part (122) opened into a circular shape or an elliptical shape in the pipe frame (120) is fixed to an outer peripheral part (111) of a cylindrical frame (110). By folding the distal end part (122) of the pipe frame (120) to the inside of the opening of the pipe frame (120), a collapsed part (121) to close the circular shaped or elliptical shaped opening is provided. The collapsed part (121) is abutted and fixed to the outer peripheral part (111) of the cylindrical frame (110). COPYRIGHT: (C)2011,JPO&INPIT
