  First, the backrest 3 is inserted into the housing portion 6S of the cover body 6 until the upper end of the backrest 3 contacts the upper end of the housing portion 6S. In this state, an unillustrated attachment line member attached to the lower end portion of the front cover 61 is provided at a position at the boundary between the backrest 3 and the seat 2 that is lower than the upper end surface of the seat 2 and is not visible in front view. It fixes by fitting in a plurality of engaging parts which are not illustrated. Next, a hand is inserted into the accommodating portion 6 </ b> S of the cover main body 6, and the bush 8 is inserted into each of the holes 71 of the plate-like body 7 attached thereto. Then, the head portion 82 of the bush 8 is positioned on the back surface 3 b side of the backrest 3, and the shaft portion 81 is fitted into and engaged with the hole 31 formed in the backrest 3. At this time, since the hole 71 has a long shape in the bending direction of the backrest 3, the shaft portion 81 of the bush 8 can be slightly moved in the bending direction in the hole 71, that is, the position of the shaft portion 81 is adjusted. And can be smoothly engaged with the hole 31.

  As described above in detail, the chair A of the present embodiment is configured such that the back cover C is attached by the attachment structure T, so that the chair A is fixed to the backrest 3 on the cover body 6 that is exposed to the outside in the conventional manner. It is not necessary to form holes or notches, and since the pins and the like are not exposed, the appearance can be improved. In addition, the aesthetic appearance of the chair can be maintained in this respect without causing breakage and fraying due to the holes and cuts. In addition, it is possible to ensure the strength and durability of the cover main body 6 that forms the tension of the backrest 3.

  In addition, since the cover body 6 is backed up by the plate-like body 7 disposed inside the housing portion 6S, the cover main body 6 is backed up even though the backrest 3 is curved backward. Can be attached in a tensioned state to prevent sticking. In particular, in this embodiment, since the plate-like body 7 is set to a size that covers substantially the entire area of the accommodating portion 6S, the effect is great. Furthermore, as shown in FIG. 9, even if it is a case where it attaches to the backrest 3 'which makes the shape recessed only partly, since the plate-shaped body 7 will be arrange | positioned so that the recessed shape may be covered. The appearance can be improved without causing the cover body 6 to bump, bend or wrinkle. This has the same effect even if the backrest has a shape that is continuously uneven. In FIG. 9, the same components as those described above are denoted by the same reference numerals without being specifically described, and the components relating to the backrest 3 ′ are denoted by “′”.

  In addition, the back cover C of the present embodiment is a type that is attached so as to accommodate the upper end portion of the backrest 3 in the accommodating portion 6S, and is inherently prone to lift and bumping. The effect of the mounting structure T is particularly effective.

  Since the plate-like body 7 is made of a flexible material, it can be fixed in correspondence with the backrest 3 having a curved shape as in the present embodiment.

  Since the plate-like body 7 is attached to the cover main body 6 by sewing, compared with the case where it is attached with a pin or an adhesive, the cover main body 6 is in a tensioned state and the wrinkles are more difficult, and also in terms of durability. Are better.

  Further, a hole 71 constituting fixing means F is formed in the plate-like body 7 in the vicinity of the opening 6K so that the plate-like body 7 and the backrest 3 are fixed in the vicinity of the opening 6K, and the plate-like body 7 and the back cover are fixed. Since C is sewn in the vicinity of the opening 6K, the aesthetic appearance can be maintained in the vicinity of the opening 6K, which is a place where bending and bumping are likely to occur.

  Since the fixing means F is configured to be fixed to the backrest 3 by the bush 8 separate from the plate-like body 7, it is only necessary to form the hole 71 in the plate-like body 7, and the production can be simplified.

  In addition, since the bush 8 is thin so that the head 82 is substantially integrated with the plate-like body in the engaged state, the bush 8 is passed through the rear cover on the back surface 3b side of the backrest 3. The shape does not appear and the aesthetics can be maintained.

  The back cover C is fixed to the backrest 3 by using holes 31 formed for the purpose of ventilation and elasticity, or for the purpose of improving the design. The convenience of manufacture can be aimed at by attaching using the hole 31 and combining a function.

  Further, in the chair A provided with the hanger part 5 as in the present embodiment, the back cover C is attached to the upper region of the backrest 3 so as to avoid the part where the hanger part 5 is attached. The cover C does not need to be processed for attaching the hanger part 5, improves the convenience of production, and ensures the durability of the back cover C and the beauty of the chair A. Furthermore, the back cover C can be replaced without removing the hanger part 5 from the chair body A1.
