ことが多い。2. Description of the Related Art This type of chair usually has a seat having a structure in which a net material is stretched inside a frame. In the case of such a structure, since the net material has to be stretched uniformly, the frame portion often has a planar shape.

【発明が解決しようとする課題】ところが、座の枠部を
平面的なものにすると、その枠部の存在により着座者に
ごつごつ感を与えてしまうことが少なくない。However, when the frame portion of the seat is made flat, the presence of the frame portion often gives the seated person a feeling of stiffness.

うという問題もある。For this reason, in the case where the frame portion made of synthetic resin is provided, the lower layer portion of the frame portion is made of a hard resin supporting the net material, and the upper layer portion is made of a soft resin. However, such a device has a problem in that the equipment and process for molding the frame part are more complicated than usual. Further, in such a structure, it is usual to insert the peripheral edge of the net material into the frame portion, but when insert molding is performed, heat is applied to the net material. Therefore, there is also a problem that the material of the net material is limited to a material that does not deteriorate or deform due to heat.

However, in the case of such a configuration, for example, when the frame portion is curved at the front edge portion along the lower limb of the seated person, it is difficult to allow the net material to follow the curved shape. In order to solve such a problem, a device such as a backup member is provided at a required position of the net material. However, unless the design is done properly, the structure becomes complicated and the manufacturing becomes difficult.
