To provide a device for taking natural wind indoors by receiving the wind by panel boards.

In this device, columns having the panel boards are inserted into holes formed in a pair of upper and lower frames, automatic angle adjusters for easily taking wind indoors are fitted to the upper and lower frames, and the entire part of the device is fitted to supporting fixtures fixed to a window frame. The wind from right and left sides blowing outdoors is received by the panel boards installed at a right angle to the window. Since the panel boards are slid laterally, an angle is automatically given to the panel boards and all the wind hitting the panel boards can be taken indoors.
