In the windbreak fence of the present invention, several sets of upper and lower panels are provided in the vertical direction by shifting the position between front and rear columns, and one panel of each set is raised and lowered by an interlocking mechanism. The feature is that it is possible.

According to the first aspect of the present invention having the above structure, the upper panel of the two vertically arranged panels is used to move up and down, so that the upper panel is used in a strong wind and the upper panel is used in a mild weather condition. If the panel is lowered, only the lower panel will be at the height and visibility will be good.

According to the second aspect of the present invention, since the column expands and contracts when the upper panel is moved up and down, the column is lowered when the upper panel is lowered, and the visibility is further improved.

According to the third aspect of the present invention, since one panel of each set of the upper and lower panels goes up and down, half of the panels are opened in the vertical direction and the columns are set up in the upright direction. The open part of the panel can be continuously formed at the same height,
The visibility becomes better.
