2. Description of the Related Art Chairs arranged for visitors in public places, such as government offices, banks, and hotel lobbies, are frequently placed in and out of the outdoors, and are frequently used. In particular, the upholstery covering the seat and the back is the most easily soiled and the dirt is conspicuous, so it is necessary to frequently replace and replace it, and the connection between the core material of the back and the seat and the upholstery is simple. In addition, it is necessary to provide a structure that enables reliable attachment and detachment.

[0003] In such a chair of the prior art, the connection between the core material and the upholstery is made by attaching one of the occlusal tapes of the slide fastener to the side edge of the core of the back or the seat and the other occlusal tape. It is known that the core material and the upholstery are configured to be sewn to the side edges of the upholstery in advance, respectively, and to be engaged with both the bite tapes to connect the core material and the upholstery.

Further, one side of a hook-and-loop fastener to be attached and detached by utilizing the entanglement of an elastic member is sewn in advance to a side edge of a core material of a back or a seat, and the other is sewn to an inner edge of an upholstery. There is also known a configuration in which the core material and the upholstery are connected by attaching the hook-and-loop fastener.

[0005]

However, such a chair has a problem in connection durability and the like.

That is, in the case of the former connection via the slide fastener, the bite tape on the core material side and the bite tape on the upholstery side are not always manufactured at the same time. In addition to the possibility that the engagement cannot be performed, the slide fastener itself is likely to be damaged and the durability is poor.

[0007] In the latter connection through the hook-and-loop fastener, the sticking force of the hook-and-loop fastener is reduced due to deterioration over time, and the sticking force is further reduced due to adhesion of lint or the like. In addition, since positioning is difficult, the appearance and comfort of the back and seat are likely to vary.

An object of the present invention is to effectively solve these problems.

[0009]

In order to achieve the above object, the present invention employs the following configuration.
