One ends 4 of the two outer cylinders 1 are closed, and drain holes 5 are formed. The two outer cylinders 1 are inserted from the left and right of the inner cylinder 2, and the outer cylinder 1 is pushed in from the left and right to constitute a support rod that is compressible against the coil spring 3. However, since the two outer cylinders 1 come off in this state, a projection 6 such as a pin is provided on the inner cylinder 2 by welding or screwing for fixing, and the coil spring 3 expands and contracts. The outer cylinder 1 is configured so as not to come off from the inner cylinder 2 by being combined with the outer cylinder 1 having a long hole 7 corresponding to the operation range. The relationship between the outer cylinder 1 and the inner cylinder 2 may be such that the inner cylinder 2 can be inserted into the outer cylinder 1 or the outer cylinder 1 can be inserted into the inner cylinder 2.

[0010] At least one L-shaped or U-shaped projection 8 is provided on each side end of the outer cylinder. Both sides of the banner, the hanging curtain are sewn into a cylindrical shape, and the upper and lower ends of the tubular shape are subjected to eyelet striking, the banner, the banner of the present invention in the tubular shape of the hanging curtain,
A hanging curtain support rod is inserted, and the L-shaped or U-shaped projection 8 is hung on a horizontal curtain, eyelets provided at upper and lower ends of a cylindrical shape formed at both ends of the hanging curtain, and the horizontal curtain and the hanging curtain are loosened.
