<P>PROBLEM TO BE SOLVED: To provide a fixing device for stretched material which can be stored/transferred without getting voluminous, and surely presses a stretched material such as an agricultural film to fix it on the surface of soil when used. <P>SOLUTION: The fixing device for a stretched material 1 includes a soil-stabbing part 2 stabbed into the soil through the stretched material downward from above and a head-pressing part 3 mounted on the top end side of the soil-stabbing part to press the stretched material from above, and is provided with saw blade-like retaining teeth 4 which is formed at the side edge of the soil-stabbing part 2 to prevent the soil-stabbing part from getting out of the soil. The fixing device is made of a corrugated board, and is structured as follows: the corrugated board is set with its corrugated lines put in a vertical direction in the soil-stabbing part 2; the soil-stabbing part 2 and the head-pressing part 3 are connectedly set up via a folding line 5 perpendicular to the corrugated lines; and the soil-stabbing part 2 and the head-pressing part 3 are bent along the folding line 5. The fixing device is spread out without being bent so as to entirely become a flat plate state and thereby does not get voluminous, when stored/transferred. The head-pressing part 3 is bent based on the soil-stabbing part 2 along the folding line 5, and the soil-stabbing part 2 is stabbed into the soil when used, so that the head-pressing part 3 surely presses the stretched material. <P>COPYRIGHT: (C)2012,JPO&INPIT |
