And, as shown in FIGS. 56, 57 and 58, 59 and 60, the horizontal axis 3 (first horizontal axis 31, second horizontal axis 32) is formed by folding back the end portion of the seat surface 5. It may be attached to the bottom of the. Although only one end of the seat surface 5 is shown in FIGS. 43 to 60, the other end of the seat surface 5 is also folded back like the one end of the seat surface 5 although not shown. In this way, it may be attached to the bottom surface of the horizontal axis 3 (first horizontal axis 31, second horizontal axis 32).

The following example describes a folding chair C capable of keeping the seat surface 5 firmly (FIGS. 61 to 66).
That is, the pair of X-shaped leg portions 1 and 2 has the X-shaped first leg portion 1 and the X-shaped second leg portion 2, and the X-shaped first leg portion. Reference numeral 1 denotes a first leg 11 and a first' leg 11', and an X-shaped second leg portion 2 is a second leg 21 and a second' leg 21'.
