DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on embodiments shown in the drawings. FIG. 1 is a diagram showing a fastener 1 of a greenhouse greenhouse band according to an embodiment of the present invention.

The fastener 1 is formed by bending an elastic wire, and as shown in FIG. 1 (c), is bent in a mountain shape with a flat top near the top as viewed from the front and a widened skirt. More specifically, the vicinity of the top of the front mountain-shaped fastener 1 is shown in FIG.
As shown in (b), when viewed from above, the band mooring portion 11 bent in a substantially M shape is formed. Further, both ends of the substantially M-shaped band mooring portion 11 are bent at substantially right angles, respectively, and have two relay portions 12 and 13 formed so as to expand in a skirt (FIG. 1A,
(D)). In addition, linear hem portions 14 and 15 are provided so as to expand outward from the respective ends of the relay portions 12 and 13. And the other straight hem 1
As shown in FIG. 1, the end portion 5 is slightly bent in the direction of the band anchoring portion 11, then bent in the direction opposite to the bending direction of the band anchoring portion 11, and further bent inward in a substantially U-shape. A mounting knob 16 is formed. The shape of the mounting knob 16 is not limited to this, but may be, for example, bent into a circle or the like.

The band mooring portion 11 is formed so as to abut one side surface of a plastic film stopper 2 to be described later, and is formed so that the linear hem portions 14 and 15 abut the other side surface. One side and the other side of the stopper 2 are urged to spread by the elastic force of the fastener 1. Therefore, the relay units 12 and 13 are connected to the band mooring unit 11.
The length is adjusted so that the straight hem portions 14 and 15 can exhibit such a function.

The reason why the band mooring portion 11 is formed in a substantially M-shape as described above is that the band mooring portion 11 is formed on one side surface of the plastic film stopper 2 by processing as described above. When trying to abut, the four wire portions 11a to 11d constituting the band mooring portion 11 abut on one side surface of the plastic film stopper 2. Therefore, if processed in this way, the wire portion 11
The house band 3 is alternately wrapped around at least two of the line portions a to 11d, so that the house band 3
Is pressed against one side surface of the plastic film stopper 2, so that the house band 3 can be fixed without being bound. A specific method of fixing the house band 3 will be described later.

The fastener 1 according to the present embodiment can be applied, for example, to the following plastic film stopper 2. A description will be given based on FIGS. 4 and 5.
