There are problems such as soiling, and snowfall on the floor surface during heavy snowfall, requiring snow removal work. On the other hand, when a fence with a certain height is stretched over the handrail wall, there is a risk that snow will blow through the gaps between the fence constituent members.

Further, even in the handrail wall having the above fences standing upright, there is a wide space between the upper end of the fence and the eaves of the building, and snowstorms pass through this space to the veranda or balcony. It is not possible to prevent blowing on the floor surface. Most of these problems can be solved by increasing the fluence, but provision of such a high fluence even in seasons other than winter has the problem of impairing air permeability and daylighting. .

The present invention has been made in view of the above problems, and an object thereof is to shield the upper space of the handrail wall to prevent snow during snowfall in winter.
Another object of the present invention is to provide a snow-removing shutter device which can be opened to open the space above the handrail wall completely in fine weather or the like other than snowfall.
