PROBLEM TO BE SOLVED: To reduce wind receiving pressure of a net, and to also improve the wind reduction effect, without expanding an installation space of a windbreak facility.SOLUTION: A windbreak facility 1 comprises a plurality of installation parts 3 for installing a net 2, and a plurality of nets 2 are installed along the vertical direction between the respective installation members, and among the mutual nets adjacent along the vertical direction, a width D of a lower net 2b relatively positioned in a lower part, is longer than a width (d) of an upper net 2a relatively positioned in an upper part. Thus, a clearance (a slit) is formed between the upper net and the lower net, and a part of wind received by the lower net flows so as to rise in its clearance. As a result of it, wind receiving pressure of the net can be reduced, and the wind reduction effect can also be improved. |
