In addition, the suction device B is composed of a disc-shaped ferromagnetic plate 3 similar to the suction device A and a ferromagnetic pusher 3a protruding from the center of one surface on the suction side. One end of the ferromagnetic pusher 3a is a small-diameter scale part 3a', which is inserted into a hole provided at the center of the ferromagnetic plate 3, and the narrow-diameter scale part 3a' is also connected to the non-adsorbing side of the ferromagnetic plate 3. The protruding portion is considered to be a wood screw 5.

In addition, when the wood screw 5 is welded by spot, brazing, or other welding to the non-adhesive surface of the ferromagnetic plate 3 on which the ferromagnetic push part 3a is protruded, the wood screw 5 is formed integrally with the push part 3a by pressing or the like. In some cases, the ferromagnetic plate 3 is pierced through a hole provided in the center of the ferromagnetic plate 3 and crimped, or it is formed integrally with the ferromagnetic plate 3 and the pusher 3a. Incidentally, the protruding portion of the small diameter scale portion 3a' may be a nail 5''.

Further, the other end of the curtain binding band 6, to which the suction device A is attached, is inserted by the wood screw 5 of the suction device B, and is fixed by screwing the wood screw 5 into the window opening C. ing.
