PROBLEM TO BE SOLVED: To provide aroma dispersion equipment capable of dispersing aroma in a wide range using a rotary ventilator that rotates by natural wind, and a harmful animal repelling method using the aroma dispersion equipment.SOLUTION: Aroma dispersion equipment includes container means with a circular bottom face, in which a repellent a harmful animal avoids or liquid that emits an aroma is arranged, cylindrical body means attached to the upper part of the container means, ventilator means rotatably held by the body means, and columnar support means for supporting the body means. The ventilator means is roughly of a cylindrical shape having a plurality of window parts. The central part of the ventilator means is rotatably held by a center shaft member of the body means, and the ventilator means rotates by the wind force generated when the wind hits the plurality of window parts. When the ventilator means rotates, the container means causes the vaporized repellent or the aroma to pass through the cylindrical inside of the body means, and be dispersed to the surroundings.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】自然風で回転する回転式ベンチレーターを用いて広範囲に拡散することができる香気拡散装置及びその香気拡散装置を用いた害獣忌避方法を提供すること。【解決手段】底面が円形の容器で、前記害獣が避ける忌避剤または香りを発する液体を配置する容器手段と、円筒形で、前記容器手段の上部に取り付ける本体手段と、前記本体手段に回転可能に保持されるベンチレーター手段と、前記本体手段を支持する円柱形の支柱手段とを有し、前記ベンチレーター手段は、複数の窓部を備える略円筒形であり、該ベンチレーター手段の中心部を前記本体手段の中心軸部材で回転可能に保持されて、風が前記複数の窓部に当たったときの風力で回転し、前記容器手段は、前記ベンチレーター手段が回転したときに、気化した前記忌避剤または前記香りを前記本体手段の円筒形の内部を通過させて、周囲に拡散する、ことを特徴とする。【選択図】図1
