PROBLEM TO BE SOLVED: To provide a mesh stretching structure of a chair which can be set manually and easily.SOLUTION: A mesh stretching structure comprises: a base frame 11 supported by a leg part; at least a pair of facing subframes 12 for fixing a mesh covering fabric 1; and an extension mechanism (for example, consisting of a fastening screw 13 and a screw hole 28 or a nut part 17) for fixing the mesh covering fabric 1 to the base frame 11 in a state of applying tension to the mesh covering fabric while making the subframes 12 movable in a stretching direction of the mesh covering fabric 1 with respect to the base frame 11. When the subframes 12 are fixed to the base frame 11, an interval between the subframes 12 is extended and tension required as a body support surface is applied to the mesh covering fabric 1.SELECTED DRAWING: Figure 6 |
