<p>PROBLEM TO BE SOLVED: To provide a roll-up preventing device for kudzu-vine or the like which facilitates carriage and makes a roll-up preventing effect high and satisfactory. SOLUTION: A main body 4 of device is made into right hexagonal cylinder by bonding a pair of half divided bodies 1 and 2 in the direction of axial line, the respective divided bodies 1 and 2 are injection-molded by light shielding synthetic resins, and one terminal part in peripheral direction is integrally formed while being linked through a hinge part 3. The respective divided bodies 1 and 2 are mounted on a branch while being closed by engaging the other terminal part in peripheral direction through an engage means in the state of sandwiching the branch. Since the outer form of viny plant vertical to the axial line is hexagonal, contact with the main body 4 of device is reduced, the plant is easily dropped downward and hardly rolled up. Besides, its peripheral length is shortened in comparison with the cylindrical main body of device, materials for forming the main body 4 of device are reduced, and the main body 4 of device is made light in weight as well.</p> |
