による閉塞板４のガタツキ等も防止できる。 In order to maintain the ventilation opening in an open state or a closed state, as shown in FIG.
By attaching a knob 6 from the opposite side through the long holes 5, 5 made in the board 3 and moving the knob 6, the length of the long hole 5, that is, the width of the ventilation port 7 is closed. There is a device that allows the plate 4 to slide.In this case, elastic members 8 are attached to both sides of the center inside the knob 6, and the closing plate 4 is pressed against the base plate 3 by the pressing action of the elastic members 8. , one in which movement of the closing plate 4 is prevented is known. (Refer to Japanese Utility Model Application No. 56-31191.) This device can also prevent rattling of the closing plate 4 due to wind.

[Problem that the invention attempts to solve]
