In particular, the first component 4, the second component 7, and the third component 10 are bridged between the two first strut members 2, the second strut member 5, and the third strut member 8 and between them. Since it is composed of the member 3, the second bridging member 6, and the third bridging member 9, each part becomes a flat flat surface when disassembled, and even if three of them are placed on top of each other, it does not take up space. Therefore, it can be stored in a bag or the like and carried around, and can be easily loaded into a car, and can be used both outdoors and indoors.

Further, when assembling the assembly type chair 1, the two third strut members 8 are formed into the first load receiving portion 13 by simply inserting the third component 10 into the place where the first component 4 and the second component 7 are temporarily tightened. , The angle between the first component 4 and the second component 7, that is, the posture as a chair is determined by being supported by the three points of the second load receiving portion 17 and the third load receiving portion 22. That is, the third component 10 has not only a seating function having a surface on which the user sits, but also an angle determining function and an angle holding function for determining the angle and height of the chair by inserting the chair. According to such a structure, the stability of the assembled chair 1 is improved, and the posture of the chair is not maintained only by the fastening force of the fastener 15, so that the fastener 15 is tightened more than necessary. There is no need. Therefore, no tools are required for assembly and disassembly, and handling is easy.

The assembly-type chair 1 can determine and hold the angle of the chair by supporting the third component 10 only at two points, the first load receiving portion 13 and the second load receiving portion 17. When the chair is supported by three points including the third load receiving portion 22, the stability as a chair is further improved.
