In addition, since the screw holes and the like do not remain on the backrest 6 even after the hanger 21 is removed, the appearance is good.

  Further, since at least the inclined standing frames 27 and 27 and the upper frame 28 are formed of an elastically deformable material, when the upper frame 28 is loaded with clothes or the like, the inclined standing frames 27 and 27 and the upper frame 28 are The frame 28 is elastically deformed, and the left and right support frames 26, 26 use the mounting members 22, 22 as fulcrums, specifically, the tip of the contact piece 25 c of the elastic member 25 contacts the rear surface of the side rod 12. The moment which tries to rotate downward is used as a fulcrum, and the mounting members 22 and 22 are strongly engaged with both sides of the backrest 6 by the moment, and the mounting members 22 and 22 and the backrest 6 There is also an advantage that the bonding strength of is increased.

  Since the upper frame 28 is curved upward in an arc shape when viewed from the back, the upper frame 28 is easily bent with respect to a load from above, and the stress can be dispersed.

  In addition, since the auxiliary frame 29 is curved downward in an arc shape in the rear view, accessories such as a tie, a muffler, and a stall can be hung on the auxiliary frame 29, which is convenient. In addition to the increase, accessories such as clothes hung on the auxiliary frame 29 are close to the center of the auxiliary frame 29, so that even when the upper frame 28 is covered with a jacket, it is easy to take them out.

  In addition, since the center portion of the auxiliary frame 29 is positioned in front of the center portion of the upper frame 28, clothes can be attached to the auxiliary frame 29 even when the upper frame 28 is covered with a jacket. Goods can be easily hung and taken out.

  Since the left and right mounting members 22 are mounted on both sides of the backrest 6 so that the vertical mounting position can be adjusted, the upper frame 28 is level with the upper end of the backrest 6 when the hanger 21 is not used. Alternatively, the hanger 21 does not get in the way by being positioned at a lower position below it, and when the hanger 21 is used, the upper frame 28 is located above the upper end of the backrest 6. By positioning the garment etc. on the hanger 21, it is easy to hang the garment etc. on the hanger 21, and the lower end of the garment etc. can be prevented from sticking to the floor.
