By making the elastic frame 20 bend, the elongation and contraction of the sheet-like display material 2 can be absorbed, and a state without wrinkles or slack can be always maintained. Note that the sheet-like display material 2 may be stretched between the connecting rod 4 and one of the engaging rods 5.

FIG. 5 shows a sheet-like display material extending structure of another embodiment.

A fitting connection frame 24 is formed by fitting two flat V-shaped frame members 23, 23 as inelastic frame members to each other. A separation plate 25 is provided at a portion corresponding to the bottom of each frame member 23, and the screw rod 3 is disposed between the separation plates 25, 25.
3 is inserted, and the frame members 2 are adjusted by adjusting the screw rods 3.
The fitting depth of 3, 23 can be changed.

At the front ends of the frame members 23, 23, the rods 2
6, a sheet-like display material 2 formed in an annular shape is fitted on the outside of the rods 26, 26.

According to this embodiment, an appropriate tension can be applied to the sheet-like display material 2 by adjusting the fitting depth of the frame members 23 by the screw rod 3.

Further, in the portion of the screw rod 3 in the, rather 如shown in FIGS. 1 and 2, by installing a coil spring, give flexibility to the fitting depth of the frame member 23, the sheet-like display It is a structure that absorbs the wood 2 elongation and contraction (Fig.
Not shown) .
