 ハンガー21は、この例では、背凭れ6の左右の両側部に上記のようにして装着した上記の1対の取付部材22、22と、両取付部材22、22から、背凭れ6の背面側において互いに内方に向かって延出する1対の支持フレーム26、26と、両支持フレーム26、26の内端より上方に向かって互いに外側方に拡開するように延出する1対の傾斜起立フレーム27、27と、両傾斜起立フレーム27、27の上端部に各端部が連設された左右方向を向く上部フレーム28とを備えるものとし、少なくとも、上記傾斜起立フレーム27、27と上部フレーム28とを、弾性変形可能な材料により形成してある。 In this example, the hanger 21 includes a pair of mounting members 22, 22 mounted on the left and right sides of the backrest 6 as described above, and the backside of the backrest 6 from the two mounting members 22, 22. A pair of support frames 26, 26 extending inward from each other and a pair of slopes extending so as to expand outward from the inner ends of both support frames 26, 26. The upright frames 27 and 27 and the upper frame 28 facing the left and right direction, each of which is connected to the upper ends of the inclined upright frames 27 and 27, are provided. The frame 28 is formed of an elastically deformable material.
 また、上部フレーム28より下方において、左右方向を向く補助フレーム29の両端部を、左右の傾斜起立フレーム27、27に連設してある。
 この例では、上部フレーム28を、背面視において、上方に円弧状に湾曲させ、また、補助フレーム29を、背面視において、下方に円弧状に湾曲させ、上部フレーム28と補助フレーム29との左右の両端部同士を、左右の傾斜起立フレーム27、27の上端部に、互いに結合するようにして連設してある。
Further, below the upper frame 28, both end portions of the auxiliary frame 29 facing in the left-right direction are connected to the left and right inclined standing frames 27, 27.
In this example, the upper frame 28 is curved upward in an arc shape in the rear view, and the auxiliary frame 29 is curved downward in an arc shape in the rear view, so that the left and right sides of the upper frame 28 and the auxiliary frame 29 are Are connected to the upper ends of the left and right inclined upright frames 27 and 27 so as to be coupled to each other.
 さらに、補助フレーム29の中央部は、上部フレーム28の中央部より前方に位置させてある。 Furthermore, the central portion of the auxiliary frame 29 is positioned in front of the central portion of the upper frame 28.
 ハンガー21は、取付部材22、22における包囲片23、23と、支持フレーム26、26と、傾斜起立フレーム27、27と、上部フレーム28と、補助フレーム29とを、硬質合成樹脂材料により一体成形し、弾性部材25、25だけ別材料により形成して、これをボルト・ナット25dをもって包囲片23、23に取り付けるようにするのが好ましい。 The hanger 21 is formed by integrally molding the surrounding pieces 23 and 23 in the mounting members 22 and 22, the support frames 26 and 26, the inclined standing frames 27 and 27, the upper frame 28, and the auxiliary frame 29 with a hard synthetic resin material. However, it is preferable that only the elastic members 25 and 25 are formed of different materials and are attached to the surrounding pieces 23 and 23 with bolts and nuts 25d.
 このハンガー21は、取付部材22、22を、背凭れ6の左右の両側部に装着してあるので、応力が中央に集中することなく、左右に分散され、ハンガー21自体が左右にぐらつくことなく、衣服等を安定よく支持することができるとともに、左右の取付部材22、22を小型化することができる。 In this hanger 21, the mounting members 22, 22 are mounted on the left and right sides of the backrest 6, so that the stress is not concentrated in the center and distributed to the left and right, and the hanger 21 itself does not wobble from side to side. The clothes and the like can be stably supported, and the left and right attachment members 22, 22 can be reduced in size.
 また、ハンガー21を背凭れ6に装着したときの背面形状が2個のZ字を向き合わせて結合したようなユニークな形状を呈し、体裁がよく、しかもハンガー21を装着しているときだけでなく、ハンガー21を取り外した後にも、ねじ孔等が背凭れ6に残存することがないので体裁がよい。 In addition, when the hanger 21 is attached to the backrest 6, the back shape is unique such that the two Z-shapes are face-to-face joined, and the appearance is good, and only when the hanger 21 is attached.
