PROBLEM TO BE SOLVED: To provide a low wind pressure bird injury prevention device having low air resistance and receiving low wind pressure even in a strong wind.SOLUTION: In a rotary bird injury prevention device to which a pair of plastic molded bodies 1a, 1b can be rotatably attached in a coupling state, each of the plastic molded bodies 1a, 1b is provided with semi-arcuate rims 2, 3 at both ends and three parallel rod parts 4, 5, 6 integrally molded between the both semi-arcuate rims. The two rod parts 4, 6 of the rod parts are extended from outer edges of both ends of the semi-arcuate rims and formed in an approximately semicircle shape in a cross section, and the other rod part 5 is extended from the outer edge of the intermediate part of the semi-arcuate rims and formed in an approximately circle shape in a cross section. The rod parts 4, 6 are mutually superimposed in an approximately circle shape in a cross section by making the plastic molded bodies 1a, 1b couple each other.COPYRIGHT: (C)2012,JPO&INPIT【課題】空気抵抗が少なく、強風時であっても受ける風圧が小さい低風圧鳥害防止器を提供する。【解決手段】一対のプラスチック成形体1a,1bが合着状態にて回転自在に取り付けられる回転式鳥害防止器であって、該各プラスチック成形体1a,1bは、両端部の半円弧状リム2,3と、該両円弧状リムの間に一体に成形された3本の平行な棒状部4,5,6とを備え、該棒状部のうちの2本の棒状部4,6は半円弧状リムの両端部の外縁から延設された横断面略半円形のものであり、他の1本の棒状部5は半円弧状リムの中間部の外縁から延設された横断面略円形のものであり、プラスチック成形体1a,1bを合着状態とすることにより該棒状部4,6が横断面略円形に重ね合わされた状態となる。【選択図】図2
