[0013] The first frame portion 2Ap has rearward extending portions 2Apa and 2Apb and an intersection portion 2Apc. The rearward extending portions 2Apa and 2Apb are provided so as to extend further rearward than the backrest portion 2B and the leg portion 2C along the positive direction of the x-axis. The rearward extending portion 2Apa is provided on the negative y-axis side relative to the rearward extending portion 2Apb.

[0014] The intersection 2Apc is provided to connect the rear end of the rear extension 2Apa with the rear end of the rear extension 2Apb. A net member 3a is provided to hang over the rear extensions 2Apa, 2Apb and the intersection 2Apc. The rear extensions 2Apa, 2Apb, the intersection 2Apc, and the net member 3a form the article placement section 3.

[0015] The second frame portion 2Aq has forward extending portions 2Aqa and 2Aqb. A cloth material is draped over the forward extending portions 2Aqa and 2Aqb to form the main portion of the seat portion 2A.

[0016] The forward extending portion 2Aqa is provided so as to be connected to the rear extending portion 2Apa along the x-axis, and the forward extending portion 2Aqb is provided so as to be connected to the rear extending portion 2Apb along the x-axis.

[0017] The backrest 2B is a portion on which a user can rest their back when seated. The backrest 2B is formed by a second frame group 2Bf. A fabric material is draped across the second frame group 2Bf to form the main portion of the backrest 2B. The second frame group 2Bf and the first frame group 2Af are rotatably joined by a rotating portion 2AB.

[0018] The legs 2C support the seat 2A and the backrest 2B. The legs 2C are formed by a third frame group 2Cf. The third frame group 2Cf has a front leg frame portion 2Cfa, a rear leg frame portion 2Cfb, and a connecting frame portion 2Cfc. The front leg frame portion 2Cfa and the rear leg frame portion 2Cfb are rotatably joined at their upper ends at the armrest portion 2D.

[0019] The connecting frame portion 2Cfc is rotatably joined to the rear leg frame portion 2Cfb at the rotating portion 2ACb. The connecting frame portion 2Cfc is rotatably joined to the first frame group 2Af at the rotating portion 2ACa.

[0020] The armrest 2D is joined so as to connect the upper ends of the front leg frame portion 2Cfa and the rear leg frame portion 2Cfb that constitute the third frame group 2C to the second frame group 2Bf.

[0021] 3, when the folding chair 2 is stored, the first frame group 2Af, the second frame group 2Bf, and the third frame group 2Df are folded along one another. The first frame portion 2Ap, which forms the article storage section 3, constitutes the first frame group 2Af together with the second frame portion 2Aq, and is arranged on approximately the same plane, so does not affect the folded state.

[0022] The present embodiment has been described above with reference to specific examples. However, the present disclosure is not limited to these specific examples. Design modifications to these specific examples made by a person skilled in the art as appropriate are also included within the scope of the present disclosure as long as they comprise the features of the present disclosure. The elements of the above-described specific examples, as well as their arrangement, conditions, shape, etc., are not limited to those exemplified and can be modified as appropriate. The elements of the above-described specific examples can be combined in various ways as appropriate, as long as no technical contradictions arise.
