PROBLEM TO BE SOLVED: To provide a rotary bird damage prevention device that can be attached easily and firmly to an architectural structure, such as a steel tower.SOLUTION: A rotary bird damage prevention device consists of a rotating body 40 for preventing stationing, and a support tool 1 for supporting the stationing prevention rotating body 40. The support tool is constituted by providing rod-like bodies 3a, 3b between annular support members 1a, 1b. The annular support members 1a, 1b consist, respectively, of semicircular members 10, 20 where rails 11, 21 for supporting the stationing prevention rotating body 40 rotatably are formed. A V-shaped receiving section 17 is molded at the inner peripheral edge of one semicircular member 10, and a convex crimp portion 25 is molded in the other semicircular member 20 by providing curved arm-like high elasticity portions 26a, 26b on the opposite sides. An angle 30 is clamped elastically by the V-shaped receiving section 17 and convex crimp portion 25.SELECTED DRAWING: Figure 5 |
