PROBLEM TO BE SOLVED: To improve a wind reducing effect without widening an installation space of a windbreaking installation that reduces wind speed against deposited materials or the like.SOLUTION: A windbreaking installation 1 against deposited materials or the like comprises: a windbreaking member 2 which reduces wind speed and a plurality of attaching members 3 to which the windbreaking member 2 is attached, in which the windbreaking member 2 attached between attaching members 3, 3 has different opening ratio in an upper part 2a and a lower part 2b of the windbreaking member 2, and the opening ratio of the lower part 2b of the windbreaking member 2 is smaller than opening ratio of the upper part 2a of the windbreaking member 2.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】堆積物等に対する風速を低減させる防風設備の設置スペースを広くすることなく、減風効果を向上させる。【解決手段】堆積物等に対する防風設備1であって、風速を低減させる防風部材2と、前記防風部材2が取り付けられる複数の取付部材3とを備え、各取付部材間3,3に取り付けられた前記防風部材2は、当該防風部材2の上部2aと下部2bで開口率が異なり、前記防風部材2の下部2bの開口率は、前記防風部材2の上部2aの開口率よりも小さい。【選択図】図2
