Therefore, when fitting the pole 111a and the rear support pole 140 to the clamp part 330, the angle of the clamp part 330 is changed according to the inclination angle of the pole 111a and the inclination angle of the rear support pole 140, respectively. The pole 111a and the rear support pole 140 can be easily fitted to the portion 330. Moreover, since the handrail main body 310 is substantially U-shaped, the suspended state is stabilized.

  Next, a folding chair according to Embodiment 2 of the present invention will be described with reference to FIGS. The folding chair shown in FIGS. 4A and 4B is the folding chair according to the first embodiment in that the leg portion 100 ′ has a reclining mechanism 150 instead of the pair of rear support poles 140. It is different from the chair. Hereinafter, only the differences will be described in detail, and overlapping descriptions will be omitted. Note that 'is attached to the leg to distinguish it from the leg 100 of the first embodiment.

As shown in FIGS. 4 and 5, the reclining mechanism 150 includes a pair of support poles 151 (support portions) and a pair of rotating portions 152. The rotating portion 152 is a pair of elliptical plates, and the lower end portion on the rear side of the pole 111a of the X-shaped leg 110a is rotatably attached between one end portions in the length direction of the plates. A lower end portion of a support pole 151 is rotatably attached between the other end portions in the length direction of the plate. The support pole 151 has the same outer diameter as that of the rear support pole 140 and extends upward through the through hole of the upper connecting portion 130a. The upper end portion of the support pole 151 is fixed to both upper corners of the seat body 210 of the seat 200, and supports the backrest portion 212 of the seat body 210 at a predetermined angle. When the rotation unit 152 is rotated with one end portion of the rotation unit 152 as a fulcrum, the support pole 151 is further inclined from the predetermined angle as shown in FIG. Along with this, the backrest 212 is further tilted.

  The folding chair having such a configuration also rotates the handrail body 310 around the rotation shaft portion 320 as a fulcrum in the unfolded state described above (see FIGS. 4 and 5), and the X-shaped leg at the distal end portion of the clamp portion 330. When the front upper end of the pole 111a of 110a is fitted, the handrail main body 310 is suspended between the support pole 151 and the upper upper end of the X-shaped leg 110a. Thereby, the handrail main body 310 exhibits the original function of a handrail. At this time, the rotation shaft portion 320 is supported in contact with the upper connection portion 130a. The clamp portion 330 is prevented from sliding down below the stopper 113a by a stopper 113a fitted on the front upper end portion of the X-shaped leg 110a. On the other hand, in the above-described folded state (see FIG. 6), the handrail body 310 is rotated with the rotation shaft portion 320 as a fulcrum, and the attachment portion of the rotation shaft portion 320 in the support pole 151 is attached to the distal end portion of the clamp portion 330. When the lower portion is fitted, the handrail main body 310 is suspended from the upper portion and the lower portion of the upper connecting portion 130a in the support pole 151. In this state, the handrail body 310 functions as a handle for carrying the main folding chair. Therefore, the portability of the main folding chair can be improved. Moreover, since the rotation shaft portion 320 is attached to the support pole 151 so as to be movable up and down, the position of the rotation shaft portion 320 can be changed and the clamp portion 330 can be used when the handrail body 310 is used as a handle. By changing the fitting position, the position of the handle can be changed to a position suitable for each user.

  Moreover, since the clamp part 330 is rotatably attached to the other end part of the handrail main body 310, the angle of the clamp part 330 can be changed. Therefore, when the pole 111a and the support pole 151 are fitted to the clamp part 330, the angle of the clamp part 330 is changed according to the inclination angle of the pole 111a and the inclination angle of the support pole 151, respectively. 111a and the support pole 151 can be easily fitted. Moreover, since the handrail main body 310 is substantially U-shaped, the suspended state is stabilized.
